Hello, friends! Let's talk today about communal affairs. Imagine a situation (it's better to imagine than to experience it in reality) that a riser of cold or hot water has flowed in your apartment. Or we will slightly change the conditions, for example, the water supply risers flowed into apartment building... Question: who and at whose expense should repair or change them?

As it was before

In recent Soviet times the question of who owned the apartment was rather an idle one. Apartments were provided by the state, and such systems as risers - heating, sewerage, water supply - were also repaired at the expense of the state. But times have changed. Most of us have privatized our homes and become owners. And this both gives rights and imposes obligations.

From water intake to apartment

We will come back to the question of who should replace the pipes. To begin with, let's determine how the water supply scheme for an apartment building is arranged, according to what principles it operates. Simply put, this is an engineering system, which includes pipes, diluted in a certain way, devices that allow you to regulate water pressure, meters, filters, etc.

Before entering the house, water goes through several stages. From the water intake unit, it goes to the water treatment station, to the water tank, to the water pumping station, to the water supply network, and only then is it supplied to the consumer. The apartment building also has a special system so that the water gets to the consumer. She does this along the risers - vertically arranged pipes.

Code of practice

The arrangement of the system that provides the consumer with water is carried out in accordance with the construction rules reflected in the SNiP adopted in 1997. The name of SNiP is internal water supply and sewerage of buildings. The document clearly states which pipes, fittings, equipment, materials should be used. It reflects all technological processes, which must be followed rigorously.

Cast iron, steel or propylene?

What materials are most often used in the water supply system. More recently, in Soviet times, these were metal - cast iron, copper or steel - pipes. Their main disadvantage is their susceptibility to corrosion. Despite the fact that the shelf life of such pipes is quite high - according to the norms, it is 25 years, in fact it is much longer, up to 40 years. However, everything has its end, these pipes also need to be replaced.

New generation pipes have appeared on the modern market of equipment and materials. Most often, cast iron, copper and zinc are replaced with polypropylene pipes. They are durable pipes with a good shelf life, smooth inside, which prevents the formation of limescale, and therefore increases this period. They also comply with environmental requirements, and most importantly, they are resistant to corrosion.

Controversial issue

And yet, returning to the question at the beginning of the article, let's find out who should change the water risers in an apartment building. To have a clear understanding of the situation, you need to refer to the documents. The main one is government decree number 491, as well as one of the articles of the Housing Code. These documents establish the area of ​​responsibility between the owner and the company chosen by the residents.

According to the documents, the water risers are common property. Who should renovate this property? If residents have entered into an agreement with the management company, then it must definitely do this. Risers of cold and hot water supply and branches from them to the first valve are her area of ​​responsibility.

The owner of the apartment is obliged to change the plumbing at his own expense, until recently, install meters (now this should be done for free), repair pipes after the place of stop valves. Otherwise, he does not have to pay money. But what about the common property? - someone will ask. The Criminal Code will repair, but pay?

Owners also pay for these services, only they do it not at the time of replacement of pipes, but, so to speak, in advance. In the receipts that each of us receives every month, there is a line “maintenance and repair”. The price of these services is quite high in the context of all payments for housing and communal services. It is from these funds that the management company must pay for the repair and replacement of risers and water supply pipes.

Algorithm of actions

Let's briefly walk through the scheme of your actions, if you suddenly need to replace the riser and you want to do it yourself. First, you need to get permission to do this from the management company. Only this organization can disconnect the riser, which is used not only by you, but also by other residents.

Then, if you are going to cut new pipes not only in your room - from floor to ceiling, but also in ceilings, affecting the premises of neighbors, you must obtain their consent. With a positive decision, purchase pipes of the required diameter, draw up a water supply scheme and get to work.

There are many companies operating in the market for these services today. If you are not ready for independent work, you can use the services of the one whose prices and professionalism suit you. Replacing a water supply riser is, of course, troublesome, but often necessary. Observance of the algorithm specified in this article, we hope, will help you cope with the task.

No need to wait for an accident

If an accident occurs, then the riser will have to be changed in any case. Although management companies often postpone this work in every possible way, limiting themselves to the elimination of fistulas. But it is advisable to replace the risers without leading to an accident. This is best done during a major overhaul.

Today, by the way, there are such water supply schemes when pipes are removed from the field of view, hidden in various ways. It looks much more aesthetically pleasing than when they are in plain sight. The main thing is that the materials and work are of proper quality.

In this article, you will learn:

• Which is better: replacing the water supply riser in the apartment with your own hands or with the help of a team
• How to choose the right pipes
• What are the stages of the independent replacement of the water supply riser in the apartment
• What is the cost of replacing a water riser in an apartment

In old buildings, sewerage and water supply systems are constantly failing. At the same time, the installation of new pipes in the apartment (even with the use of advanced materials) or the purchase of new plumbing are not able to solve the problem. In such a situation, only a complete change of all risers that provide housing with water will save. What requirements should be followed when replacing the water supply riser in an apartment, how to connect a new riser step by step - you will learn about all this from our article.

When it is necessary to replace the water supply riser in the apartment

Water supply pipes, located vertically in the house, need to be changed when 2 situations arise: when the service life ends, and also during the complete reconstruction of the bathroom.

Replacement of such equipment depends on certain conditions and is subdivided into:

1. planned (there is a high wear of the metal structures from which the risers are made);
2. emergency (pipes are leaking or contain other defects).

In old houses there are water supply risers, which are made of cast iron or galvanized metal. The metal corrodes in any case, so after a while the pipes still need to be replaced.

The maximum wear of water supply pipes occurs in the ceilings between floors. For this reason, the connections of old pipes with new ones must be performed outside the floors: these are mainly neighboring bathrooms located above or below the floor where the replacement is being made. Metal pipes, as a rule, should last about 25 years, in fact, this period is much shorter. And after 40 years of operation, such products become truly emergency equipment.

If, at the end of the assigned service life, the water supply pipes look perfect on the outside, they still need to be replaced, since the main wear occurs from the inside. As a result, such a product can simply burst, which will entail a strong leak and, as a result, significant damage to those who live in the apartment (and, most likely, to the neighbors below too). It happens that the replacement of water supply risers in the apartment and major repairs are carried out in parallel. Pipes are currently being laid in the wall, for this reason, in the event of an emergency situation, access to the pipes will be very difficult.

Who should replace the risers

Apartment owners are often puzzled by this question. Nevertheless, it is not so easy to get a definite answer to it.

Replacing water supply structures falls on the shoulders of the housing office. After all, water supply, sewerage system, power grid - all these are public facilities.

What does the law say about replacing a water supply riser in an apartment? He confirms the above provisions with the relevant acts of the Land and Housing Codes. Moreover, for such a replacement, the owners of apartments are calculated as follows: The housing office in payment for the apartment includes the required amount, which takes into account the use of risers and pipes.

In the event of an emergency, it often breaks through the risers. The question is logical: in this case, the replacement of the water supply riser in the apartment is carried out at whose expense?

In such circumstances, the ZhEK is obliged to take all measures to eliminate the leak as soon as possible, and he is not entitled to take an additional fee from the tenants. If the apartment owners refuse to carry out repair work, their decision must be confirmed with a written statement, which may serve as a reason for legal proceedings. In this case, the court will certainly side with the service organization.

So, if you need to replace the water supply pipe, you must write an application to the appropriate management company. It is made out in the name of its head.

Before that, it will be useful to call a plumber to the apartment, who will draw up an equipment inspection report, indicate information about its damage and confirm that replacement is really necessary.

The application itself is drawn up in a free form. It is important not to forget to justify your requirement, according to which the riser should be replaced.

The application must be completed with a specific requirement to repair or replace the riser in the apartment. Please indicate the date and sign below. The paper is compiled in 2 copies. One remains with the applicant, the other is transferred to the management company.

The owner of the apartment, who draws up the application, must pay all utility bills in good faith - this is necessary so that his request can be read quickly.

If the letter is reviewed, the management company agrees with the owner on the date and time of repair work or replacement of the riser in the apartment. The specialists of the Management Company or its contractor are involved in these works.

The owner of the apartment will need an unobstructed passage from the place where the riser is located. But how much will it cost to replace the riser in the room?

Everything is very simple - when changing water supply equipment or its branches before the first docking connection, the owner of the apartment does not have to pay a dime.

But that's in theory. In practice, everything may look a little different: the apartment owner's application will be read, taken into consideration and determined to await his fate in the queue where he can spend years.

There are several possible ways of developing the situation.

1. Expect the onset of an emergency with the water supply, which may result in complete flooding of the entrance. Only in this case, the housing office will carry out repairs (in practice, the water supply riser in the apartment is often replaced only during overhaul). Sometimes it happened that even in such a situation, the restoration was done partially, and the so-called new equipment worked for a year at most.
2. Gather the apartment owners and discuss with them the issue of replacing the riser at their own expense (the cost of such a procedure is approximately 3-5 thousand rubles).

So, let's summarize how you can replace the risers in the apartment through the housing office.

You need to send an application to the management company (it was discussed above). The tenant should describe a compelling reason for the replacement. In addition, you must attach proof (photographic evidence or the results of an examination).

If the application is executed without errors, and the facts described in it do not contradict the law, the housing office must make the specified replacement or repair as soon as possible. Otherwise, the owner has the right to demand a written refusal from him, where the ZhEK will explain on what basis these works will not be performed.

If a citizen disagrees with such a refusal, it is necessary to draw up an application to the prosecutor's office, and a full package of documents that the applicant possesses is attached to it. In addition, the law provides for the possibility of replacing the riser without the necessary permission. In this case, the initiator of such work may be the owner of the apartment.

Replacing a water riser in an apartment: with your own hands or with the help of a team

Hiring professionals to replace the water supply riser in the apartment is:

• saving energy, nerves and time;
• almost always a guarantee of an excellent result;
• a considerable price for this kind of service.

An attempt to replace the water supply riser with your own hand:

• significantly cheaper than the work of a contractor;
• will require more time and labor;
• there is no guarantee of a quality result.

In other words, when the water supply risers in the apartment are replaced, the price for it can play a significant role in choosing a repair method.

To perform such a replacement, you will need to take into account the cost of not only materials, but also tools. For example, cutting polypropylene pipes will require the use of a special device. But even if we take into account such expenses, replacing the riser with your own hand may be more profitable than with the involvement of a team of workers, the savings will be especially great if you have to perform a solid amount of work.

What to do if the neighbors are not in the mood for renovation

Before starting work, you will need to enlist the support of neighbors from apartments located above and below. It is best when replacing the water supply risers in the building is performed throughout the entire entrance. In this case, the reliability of the equipment along the entire height will be the greatest.

In reality, not all the owners of neighboring apartments are ready to meet halfway and agree to the necessity to repair something from nowhere. In such a situation, you just have to connect some segment of your own riser to the existing one. Right before starting work, you need to turn off the water, which will also need to notify the neighbors. In order for residents of other apartments in the entrance to experience a minimum of inconvenience from your replacement, it is better to carry out the planned operation in the midst of a weekday - so you probably will not spoil relations with the residents.

When the replacement is carried out by the Criminal Code, difficulties of the following kind often arise: a number of neighbors simply do not let the repair team into their apartments. In such a situation, you can sue in order to obtain the necessary prescription. Or connect pipes to an existing riser segment. The first option, of course, will require a rather long wait (often more than one month), the second is somewhat worse in terms of reliability. But the pipe segment in the overlap will still need to be replaced.

How to choose the right pipes

Polypropylene products

Rusty metal pipes are usually replaced with polypropylene pipes. This choice is quite literate, since polypropylene products have a number of advantages.

Among them is the cost. When replacing pipes with polypropylene, you will immediately notice that the price-quality ratio for polymers is very favorable; this is currently the best option. In addition, these pipes have outstanding performance properties. In general, it is a very practical material with high functionality.

Polypropylene should not be confused with polyvinyl chloride or polyethylene - the latter are much more dependent on temperature changes, especially they do not like cold weather. Polypropylene treats hot water calmly, if the temperature limits are not exceeded.

Polypropylene is outwardly smooth, very resistant to physical stress. The thickness of such pipes reaches 0.8 cm, the inner part often contains fiberglass or aluminum reinforcement.

By replacing old water supply pipes with polypropylene products, you will get a pipeline with a very long service life - such pipes are not afraid of moisture and function calmly in adverse conditions.

So, the advantages of polypropylene products:

• great strength;
• lack of special skills for installation;
• the greatest tightness of the joints;
• poor susceptibility to mechanical stress;
• low price.

Reinforced-plastic pipes

Such products are of a 4-layer construction. In layers, it contains sewn polyethylene, aluminum (by the way, its thickness is 0.4 mm and it serves only for reinforcement), an adhesive layer and durable plastic (outer layer).

This is a truly universal type of communication. The name itself suggests that the product is both plastic and durable. In other words, outwardly it is immune to rust and has a long service life. And the layer from the inside gives reliability without sacrificing strength. The creators of such structures have successfully coped with the disadvantage inherent in conventional plastic pipes - the poor ability to withstand severe pressure during the water supply and excessive dependence on temperature extremes.

Advantages of metal-plastic pipes:

• resistance to rust;
• ease of connection;
• lack of an external conductive layer;
• a large number of fittings produced for these products.

Among the disadvantages is the need for regular tightening of these pipes.

So, to create a pipeline in an apartment through which cold water will flow, you can use traditional products of the corresponding diameter made of polypropylene or metal-plastic. Hot water is supplied through communications that are responsible for heating. Such pipes have increased strength and are immune to deformation loads. Manufacturers of polypropylene products say that their pipes can easily withstand 50 years of work, and if they are used for cold water this period doubles.

Stages of self-replacement of a water supply riser in an apartment

1. Organizational preparation

If your apartment is located in a multi-storey building, then you:

• using the building's water supply. She is responsible for providing water to all residents;
• must be aware that the replacement of the riser will certainly affect the residents nearest to you;
• without the participation of the housing office or the management organization, you are not able to create the conditions required to replace the water supply riser.

Therefore, you need to fill out an application in advance with the HOA or the housing office, where you need to ask to turn off the water at the entrance. This is possible, but there is a charge for this procedure. The neighbors will be warned that the water supply system will be disconnected.

In addition, when replacing, it is necessary:

• coordinate your actions with the owners of apartments on the floors below and above, since when dismantling old water supply structures, you will definitely break the floors;
• try to identify the problem of a collective change of all access risers, which will require the participation of everyone living in the entrance.

2. Materials and equipment used to replace the water riser in the bathroom

After all the issues with the housing office, management company and neighboring apartments are resolved, it is necessary to start creating a scheme for replacing water supply elements. This will help plan indoor piping and calculate exact material costs.

To perform the operation, you need to stock up on the following:

• pipes with a diameter of 32 mm (polypropylene);
• similar sized fittings;
• sealing material (silicone is better);
• metal clamps.

Water supply pipes for vertical installation are selected of the width that corresponds to the diameter of the structures to be dismantled.

To connect the riser segments, couplings with a diameter of 25 or 32 mm (depending on the selected pipe size) are used, as well as expansion joints of the same width. Polymer pipes with the steel part of the vertical water supply are connected with cuffs.

In parallel, it will be necessary to determine how the final finishing of the water supply riser will be carried out, to think over the issues of heat and noise insulation, options for the structural part of the box and its appearance.

Required tools:

• Bulgarian;
• cutting discs with a diameter of 125 mm (from 3 to 4 pcs.);
• equipment for threading;
• wrenches (adjustable and gas);
• level;
• scrap (used as a lever);
• pencil;
• chisel;
• roulette;
• different screwdrivers;
• hammer.

You also need to take care of protective equipment in advance - respirator; special glasses that do not allow dust to enter the eyes; gloves that protect against exposure to different temperatures; a hat - from dust.

3. Analysis of old water supply structures

The work carried out on the dismantling of the old steel vertical pipe, which served for water supply, is related to plumbing activities of a high level of complexity. This requires that you have the necessary qualifications and know how to handle the power tool, as well as strictly adhere to safety standards.

The first thing that is necessary is to shut off the entire water supply system, drain the remaining water from it. Such an operation is performed by a responsible person from the housing office. Otherwise, there is a chance to run into an administrative fine.

Using a grinder or a special device (pipe cutter), they cut old rusty pipes. To do this, you need to make 2 horizontal cuts (the gap between them should be equal to 10 to 15 cm). The cuts should converge at the edge of the pipe (the one closest to the wall). To prevent subsidence of the top of the pipe, such cuts are initially not made completely.

The upper pipe segment is cut according to the design height, which must be the same as the length of the press-on piece. The purpose of this operation is to make the direct axis of the pipe perpendicular to the plane of the notch.

Manipulation can be simplified by using masking tape as a guide. Its strip is glued around the circumference - the end of the tape must exactly match the beginning.

To get rid of the lower segment of the water supply riser, carefully wobble the pipe - it is important not to deform the socket itself. The butt mortar is hammered along the perimeter, and the pipe cuttings are removed with a crowbar or wedge.

Previously, cast iron pipes were connected by 2 methods:

1. suture embossing using a mortar of sand and cement;
2. sulfur filling of joints.

Cured cement is removed with a screwdriver. The simplest way to burn off sulfur is to heat the communications with a blowtorch.

The cut pieces are caught with a screwdriver and carefully removed from the floors. Stuck elements will need to be knocked out with a hammer. Then the required area is cleaned, points are marked on it for fixing the clips - they are the ones that are attached to the walls of the pipe at the wiring points.

4. Connecting a new water supply

Using a hacksaw, the pipes are cut into segments of the desired length. The connected sections are provided with marks that will tell you where the connection limit point is.

If there are old metal water supply pipes in the apartments nearby, you will need to assess their condition. Thanks to this, you can find out whether to cut the thread at the end of the metal structure. To make this easier to accomplish, machine oil is applied to the end of such a pipe.

If the metal structure is very dilapidated and there is a danger that it may not be able to withstand when threading, it is better to simply weld the pre-fitted thread to it (from 5 to 7 turns). Alternatively, the connection can be made using a collet coupling.

The connection of metal and plastic is also carried out through the thread using a coupling, while the screwing should not be excessively strong. For this, the pipe connection points are filled with tow and a special paste is applied. Before attaching the connecting adapter to the cast iron pipe, you will need to treat this place with a sealant.

Plastic parts are much easier to dock together. The joints are cleaned, then wiped with alcohol. Next, the end of the pipe and the fitting element are immediately put on the preheated apparatus, then both of them are screwed to the full depth of the nozzles. The fitting and the end of the pipe should warm up well, then the workpieces are removed and locked together.

5. The nuances of connecting to the wiring

At the attachment point of the apartment wiring and the vertical pipeline, a tee is placed, the dimensions of which should be 32 * 20 * 32 mm. To facilitate its installation, liquid soap is applied to the end of the tee. All elements are sealed.

Attention: it is advisable to install tees not with the help of couplings, but with soldering.

After installing the shut-off valve, you will need to find out if there is a leak. In its absence, the structure is attached to the wall; a level is used for its correct location. Before starting the fastening, they outline the places for the holes, into which the clips will then stand. The distance between the fasteners should be between 100 and 150 cm.

After all the fastening work has been completed, the water supply can be carried out after about 60 minutes. To ensure a sufficient degree of waterproofing and soundproofing where pipes pass through the ceilings, these places are covered with concrete to the full thickness. Finishing and other work is carried out only when the entire structure is comprehensively tested.

The cost of replacing a water riser in an apartment

Prices for replacing a riser in an apartment include the cost of materials and specialist services. In the event that you intend to do everything on your own without a certain experience, the losses can be much larger. For example, it can be fines for damage to property, both of the neighbors living downstairs and of the common house. It is not so easy to replace water stands, and the cost of even a small mistake for your (and not only) apartment in Moscow can turn out to be very expensive.

The approximate cost of replacing the water supply riser in the apartment:

Name of works	units rev.	price, rub.
Installation of a water supply riser
PVC sewer pipe laying (bath, sink, toilet, Washer)
Installation of a fan lounger pipe
Installation of the fan tee pipe
Installation of a sewer drain
Layout of pipes x / g water supply
Fastening of pipes during installation (drilling a hole, dowel, fastening)
Installation of a distributing manifold (comb type)
Installation of a valve (ball, valve)
Installation of tee, coupling, angle, adapter, American connection
Installation of water pressure regulators
Installing a plug on the pipeline
Installation of a non-return valve (plumbing, heating)

Tips for those who, together with the water supply riser, want to change the sewer riser

Change of pipes sewerage system in an apartment is performed with calculations that are somewhat more complicated. Note that dismantling in this case is not easy. However, the assembly of new structures is still faster than cold / hot water pipes. After all, the drain pipes are connected through a socket with a sealing ring, so there are no special difficulties in this operation - unless the work itself will be somewhat dirtier than when replacing water pipes or heating systems.

Replacing sewer pipes in an apartment consists of three steps:

1. Initially, the siphon elements that are located under the sinks will need to be updated. Next, calculations are performed to determine the slope of the pipes that connect the riser and the siphon. Slope refers to the difference in height above the floor between the pipe inlet and outlet. The inlet is located under the siphon itself, the outlet is on the tee of the fan riser. This height difference is directly determined by the length of the pipe.

As a rule, a pipe with a diameter of 5 cm is laid with a slope of 2.5–3.5 cm for each running meter. After determining this value, it will be necessary to carry out a projection of the dimensions onto the surface, which will be the support for the planned sewer pipe. To do this, draw the position of the branch directly on the wall. Then you can start dismantling the old drain pipes.

2. You will need to remove the fan riser, after blocking it. When removing, the pneumatic plug is inserted into the collapsible end of the riser revision, it will be a plug from neighboring drains. After that, it is required to be extremely careful to emboss the central tee - it is responsible for connecting all drain pipes in the apartment. After that, they get rid of old pipes; this operation does not require any special actions. If these are cast iron products, they are simply hit with a hammer, and the broken parts are thrown away.
3. Then it is necessary to carry out the assembly. First, a PVC pipe is placed. She is responsible for connecting the toilet bowl drain and a tee with a diameter of 10 cm (cast iron). Next, drain pipes leading from sinks and bathtubs are connected to the tee. Their diameter is 5 cm. The operation is simple - the smooth end of the pipe is connected to the socket.

After that, the revision is freed from the plug, and the riser itself is hermetically closed by simply screwing the lids. This completes the replacement of sewer pipes, and the new drainage system is ready for operation.

In this article, you will learn:

• Is the water riser in the apartment the property of the management company
• At whose expense should the water supply riser be replaced in the apartment
• What tools will be needed to replace the water riser in the apartment
• Is it possible to replace the water supply riser at the same time as the sewer riser in the apartment

Unfortunately, in the old housing stock, breakdowns of the water supply system occur quite often. A similar problem requires a solution, but the usual methods (for example, installing a pipeline from modern materials inside an apartment or buying new plumbing fixtures) are not suitable. Only replacing the water supply riser in the apartment will help in such a situation. Our article will show you where to start if you are faced with such a problem.

There are two cases when you should change the water pipes located vertically in the house. We are talking about the end of the service life and the complete reconstruction of the bathroom.

A combination of external circumstances affects the replacement of a water supply riser in an apartment. This process is of several types:

• planned (occurs with severe wear of the riser);
• emergency (there is pipe leakage or other damage).

The water supply pipes installed in the old fund are made of cast iron or galvanized metal. These materials are known to corrode over time, which means that after some time the structure will need to be replaced.

The wear of the water supply riser is most pronounced in the interfloor ceilings. As a result, the joining of old and new pipes must be carried out not in the ceilings, but in adjacent bathrooms above or below the floor where the replacement is being made. The service life of metal structures should be about 25 years, but in practice this period is much shorter. If such pipes are used for 40 years, then their condition will become truly emergency.

Sometimes it is found that the service life has expired, but visually it seems that the pipes of the water supply system are still in excellent condition. However, even in this case, the pipes must be replaced, since the main operational load falls on their inner part. If you continue to use the structure, then at some point it can simply burst, as a result of which a leak is formed, which will cause serious damage to both you and your neighbors. In some cases, the water supply riser in the apartment is replaced during overhaul. Today, pipes are placed inside walls, which makes it difficult to get to them in the event of an accident.

Is the management company obliged to replace the water supply riser in the apartment

The Housing Code of the Russian Federation obliges management companies to regularly replace common house equipment and repair the house. Funds for these activities are taken from the monthly contributions of the tenants.

The management company, in accordance with the norms for servicing the MKD, must pay for such works as:

• maintenance and repair of common household property intended to ensure the full functioning of the house;
• maintenance of communications;
• planned repairs;
• repair in emergency cases caused by the fault of the management company.

Summarizing the above, we get that the Criminal Code must pay for all repairs and maintenance of common household property (provided that it is owned by this house).

The Criminal Code must independently pay for the replacement of such elements of communication systems as:

• gas supply pipes;
• water supply pipes (up to pipes intended for distributing water inside the apartment);
• heating system (unless the residents themselves repaired or changed batteries / pipes);
• pipes for drainage (before connecting to the pipes of the apartment);
• ventilation;
• power supply.

The homeowner makes contributions to the account of the management company every month, thereby forming a fund of funds intended for repair work and maintenance of common house equipment. Homeowners do not have to pay for the replacement of the sewerage on their own and have the right to demand compensation for all costs incurred in connection with the replacement of the water riser in the apartment.

What is a plumbing riser? This is a vertical section of the pipeline, at the base of which a shut-off valve is located. The water supply system belongs to the common house property, therefore, its replacement must be paid exclusively by the Criminal Code (Housing Department or Housing Office), without charging any additional payment from the tenants.

The owner of the apartment is only required to submit an application addressed to the head of the HOA, describing the essence of the problem that has arisen. However, if the house is not on the balance sheet of the housing office, the repair of the common property must be paid for by the residents.

Everything that is located on the riser section up to the first shut-off valve also belongs to the common property. If there is no shut-off device up to the mixer itself, then this area should also be considered as part of the common property.

The water supply stands are equipped with taps, which are necessary in order to be able to shut off the water. Reinstallation of these valves is carried out simultaneously with the replacement of the pipeline.

In cases where the tenant has started a major overhaul, plans to make redevelopment with hidden pipeline laying, or is going to move the water supply riser to another place, the owner of the apartment pays all costs himself.

The owner of the home must obtain permission to carry out redevelopment in the UK if the common property is involved in the process of work. You should invite specialists and start work only after obtaining such permission.

At whose expense is the replacement of the water supply riser in the apartment made?

In cases where it is necessary to replace the water supply riser in the apartment, you should first submit an application to the Criminal Code addressed to its director.

However, even before that, it is recommended to call a plumber to the house, who will inspect the equipment and draw up an appropriate act, indicating in it the degree of wear, the existing damage, and also give a conclusion that replacing the water supply riser in the apartment is an objective necessity.

There is no generally accepted form of such a statement, the main thing is to indicate the reason for replacing the water supply pipes in the apartment.

At the end of the application, it is necessary to clearly formulate the requirement to carry out repairs or to replace the water supply riser in the apartment. Also, the current date and signature should be put under the text. The application must be made in two copies, one of which is submitted to the Criminal Code, and the other remains with the tenant.

In order for your application to be reviewed as soon as possible, you must regularly pay all utilities.

After the Criminal Code positively resolves the issue on your application, its employees should discuss with you the date and time of the repair or replacement of the water riser in the apartment. Employees of the management company or a contractor hired by it take part in the repair work.

The owner of the apartment must provide free access for specialists to the elements of the water supply system.

Another important question: what is the cost of replacing a water riser in an apartment?

In theory, everything looks simple: the tenant does not have to pay for the replacement of elements of the water supply system up to the first docking connections.

However, in reality, the situation may develop somewhat differently: the Criminal Code, having received your application and having studied it, will put you in the queue of those pending a decision. It is worth noting that the waiting period can drag on for years.

There are two main options for the further development of events:

1. Wait until an accident occurs in the water supply system of the house, which is fraught with flooding of the entire entrance. This will prompt the housing department to carry out repairs (usually the management company replaces the water supply riser only when overhaul). It happens that under such circumstances, repairs are carried out partially, and the newly installed equipment fails after a year.
2. Conduct a meeting of residents to discuss the organization of replacing a water supply riser at their own expense ( total cost work is about 3-5 thousand rubles).

Summarizing the above, we find that to replace the water supply riser in an apartment, it is necessary to adhere to a certain algorithm of actions. First, you should submit an application (see above) to the Criminal Code. Secondly, it is important to indicate a serious reason for replacing the equipment, as well as to attach to the application visual evidence of the situation that has arisen (photographs, expert opinion).

How is the water supply riser in the apartment replaced?

Water risers are located in the bathrooms a short distance from the wall. A shut-off valve must be placed on the riser to shut off the water supply.

When repairing water supply pipes, it is recommended to change the entire span at once, but this is not always possible to do. In this case, at least the section of the riser between the floor and the ceiling must be replaced. It is impossible to replace only a rusted small section of the pipe.

When replacing water supply structures in an apartment building, it is necessary to notify the rest of the residents about the time of work. You also need to contact neighbors living directly above and below you for permission to work on their territory if necessary, since new structures will pass through the floors.

Neighbors have the right to refuse, in this case, you will have to work only within the framework of your apartment - on the floor-to-ceiling section in the bathroom. It is very important that free access to the pipe joints is organized. This will quickly seal the leak if it does occur.

The housing department is obliged to replace the water supply riser in the apartment as requested in your application, if you have drawn up the document correctly and brought serious facts as evidence that comply with the norms of the law. Otherwise, you have the right to request a written refusal from the Criminal Code, which will contain the reasons for such a decision.

If you do not agree with the decision made, then you should write another statement - to the prosecutor's office. It is worth adding to the paper all the documents related to this problem and available in your hands. Also, according to the legislation, it is possible to replace the water supply riser in the apartment without the appropriate permission, while the work on replacing the equipment must be authorized by the owner of the home.

Stage 1 - selection of materials.

After agreeing on all the nuances with the management company and neighbors, you can start drawing up a diagram. This is necessary in order to find out the features of the piping in the bathroom, as well as find out how much materials you need.

To replace a water supply riser in an apartment, you will need:

• polypropylene pipes D 25 mm (or 32 mm);
• fittings of the appropriate diameter;
• metal clamps;
• silicone sealant.

To install a vertical pipeline, you should choose pipes of the same diameter as those of the elements to be replaced.

For joining parts of the structure, compensators D 25 mm (or 32 mm) and couplings are used, and transition cuffs are used to connect plastic and steel pipes to each other.

In the old housing stock, steel pipes VGP are used to conduct gas, water and heat in apartments, therefore it is easier and more expedient to choose structural elements from the same material to replace equipment.

You also need to plan the final design of the riser - decide whether you will make heat and sound insulation, how the box will look like.

In addition, it is worth preparing protective equipment: thermal protective gloves, construction goggles, a respirator and a hat.

You may also find it useful to have several plastic elbows with a diameter of 10 cm and an angle of 45 ° C. They are used in cases of displacement or alignment of a vertical pipeline. Another necessary tool is a soldering iron with different-sized Teflon nozzles - it is needed for welding polypropylene pipes.

As a rule, the replacement of the water supply riser by the management company is carried out on weekdays from 10 to 15 hours. At this time, most people are at work, and therefore they will not experience discomfort in connection with the work.

You cannot overlap the riser on your own, for this you should contact a specialist. Usually, the whole process of replacing a water supply riser in an apartment takes from half an hour to an hour. However, too much haste can lead to the fact that you miss any significant nuances.

It is possible to facilitate the replacement of cast iron pipes by using a pipe cutter. This tool is equipped with cutting pins / rollers, which gives a smooth edge at the cut.

Stage 2 - dismantling of old pipes.

The work related to the dismantling of a vertical pipeline from a water-gas supply steel pipe is one of the most difficult in the plumbing industry. These operations can only be performed correctly by experienced professionals who know how to handle power tools. Also, when working, it is worth strictly adhering to the labor protection requirements.

The quality of the installation of a new one depends on whether the old pipeline was disassembled correctly.

First of all, you should block the riser and drain the water. This should be done by an employee of the ZhEK. If you try to do it yourself, you will receive an administrative fine.

Next, using a grinder or pipe cutter, you should dismantle the old structures. For this purpose, 2 horizontal cuts (10-15 cm long) are made, which converge at the edge of the pipe adjacent to the wall. In order to avoid subsidence of the upper part of the pipe, the initial cuts are not made completely.

To extract the cut area, you can make additional vertical cuts or drive in wedges. A section of the pipe is cut from above to the calculated height, which is equal to the length of the shaped part intended for pressing during installation. The technician must ensure that the plane of the notch is perpendicular to the inner axis of the pipe.

To facilitate this operation, it is recommended to use masking tape: it should be glued in an even ring (the beginning and the end must match exactly).

To remove the bottom of the pipe, gently loosen it. The main thing is that the bell remains intact. Then the mortar should be hollowed out around the perimeter. Armed with a wedge or crowbar, they take out the cut parts.

Previously, the joining of cast iron pipes was carried out using one of the following methods:

• by using sand-cement mortar for embossing seams;
• using sulfur for pouring.

You can clear the pipe from the hardened cement mortar by digging out the surface of the seam with a screwdriver. The easiest way to remove sulfur is by burning it out: to do this, you need to warm up the structural parts of the water supply riser with a soldering iron. In order to control the draft in the riser, a metal or asbestos-cement shield should be placed on top of the pipe. After warming up the riser, you can easily disassemble it at the docking points.

You can get the parts obtained after cutting the pipe with a screwdriver. If any elements are stuck, they are knocked out with a hammer. On the received free space make markings for clips intended for fixing pipes in the wall at wiring points.

Stage 3 - installation of a new pipeline.

At this stage, they are engaged in cutting pipes to the desired length. To do this, use a hacksaw for metal or scissors for cutting polypropylene. Marks are made at the joints of the structural parts to indicate the connection point.

You should pay attention to what material the neighbors' water supply risers are made of. If they are metal, then it should be analyzed whether their condition allows threading from the end side. You can make cutting easier by lubricating the end of the pipe with machine oil.

Taking a grinder with a grinding disc, you should trim and remove the tapered chamfer from the pipe cut along the entire perimeter. Sometimes, a metal pipe that is present can seem unreliable. In this case, in order to avoid the risk of damage to it, you should simply take the finished thread (5–7 threads) and weld it. An alternative solution can be the joining of parts by means of a collet coupling, to which, in turn, an adapter coupling with a thread suitable for installing plastic pipes is attached.

When installing the pipes, little effort should be made when tightening. This effect is created artificially by placing a linen roll at the joints and coating them with investment paste. Before placing the adapter on the cast iron pipe, sealant is applied to the joint.

It is much easier to connect two plastic elements - the joints are pre-cleaned and degreased with an alcohol compound.

To weld polypropylene pipes to each other, a welding iron with a Teflon nozzle is required. Welding takes place at a temperature of approximately 250 ° C. On the heated device, the nozzle and the fitting and the end of the pipe should be put on the full depth at the same time. After that, the parts of the structure should be properly heated, and only after that they are removed and joined to each other.

Where the joint of the vertical water supply riser with the apartment wiring will be located, a tee with parameters 32/20/32 or 25/20/25 is mounted (depending on the pipe diameters used). To make it easier to install this tee, liquid soap is applied to its end. Parts of the structure are soldered. If you want to install a heated towel rail in the bathroom, then 2 more tees are installed on the riser.

Keep in mind that the best way to connect tees is by soldering rather than using couplings.

After the shut-off valve is installed, it is worth checking for leaks. If everything is fine, then the connected elements are attached to the wall. For this purpose, marks should already be made on the wall for drilling holes for clips. The distance between the fasteners should be approximately 1–1.5 m.

You can run water through the riser at least an hour after the end of the pipe joining. It is also worth remembering the need to ensure proper waterproofing and sound insulation. For this purpose, the places in which the pipes cross the ceilings must be concreted throughout the entire thickness. However, finishing work (including this one) should be carried out only after you have checked the strength of the structure.

Replacing the water riser in the apartment, if the neighbors are against

We have already said that before starting work on replacing the water supply riser in an apartment, it is worth negotiating with the neighbors living below and above you. The best option if the riser will be changed all over the entrance at once. This approach will allow you to do everything as efficiently as possible.

However, in life, it is far from always possible to find mutual understanding with neighbors. Many are not ready to start unplanned repairs. If you find yourself in such a situation, then you just have to connect some part of your apartment building to the common riser.

Immediately before you start replacing the water supply riser in the apartment, you should shut off the water and notify the neighbors about this. To keep the discomfort and frustration of other residents to a minimum, try to arrange for replacement work in the middle of the working day, when most of your neighbors will be at work.

Specialists of the management company, if it is they who are engaged in the replacement of equipment, are often faced with a problem of a different kind - many neighbors refuse to let workers into their apartment. Finding yourself in such a situation, you can go to court or change the section of the common riser only in your apartment. If you choose the first path, then the resolution of the issue may take up to several months. The second method does not guarantee 100% quality. However, you still have to choose some way to solve the problem.

Tips for those who replace water supply risers and sewer pipes in an apartment on their own

Replacing a water supply riser in an apartment is somewhat easier than a sewer one. For the latter, some calculations still need to be performed. And you will have to tinker with dismantling the sewer riser. But you will be able to assemble new structures much faster than connecting pipes for hot and cold water. This is due to the fact that the connection of the drain pipes takes place through the socket by means of a sealing ring. The only caveat is that during this operation you will most likely get dirty much more than when performing other work.

When replacing a sewer riser in an apartment, you should adhere to the following algorithm of actions:

1. First of all, it is necessary to install new siphon elements that are located under the sink. After that, you need to calculate the slope of the pipes connecting the riser and the siphon itself. The slope is the difference in heights at which the inlet and outlet of the pipe are located above the floor. Typically, the outlet is located on the tee of the fan riser, and the inlet is directly above the siphon. The slope depends on the length of the pipe.

   So, to install a pipe with a diameter of 5 cm, the slope will be 2.5–3.5 cm per linear meter. Having calculated this parameter, you should create a projection of dimensions on the surface, which you will use as a support for the sewer pipe. For this purpose, the drawing is drawn up directly on the wall. After that, you can begin to disassemble the old drain pipes.

2. It is necessary to close and dismantle the fan riser. At the same time, a pneumatic plug should be inserted into the collapsible end of the riser revision, which will fence off your drain from the neighboring ones. Next, you should very carefully emboss the central tee, into which all the drain pipes in your apartment converge. After that, it is the turn of a rather simple operation to dismantle the old pipes. If the old pipes in your apartment are made of cast iron, they should simply be knocked out with a hammer and thrown away.
3. Then you should proceed to the assembly of the structure. First of all, a polyvinyl chloride pipe is installed, which is responsible for joining the toilet drain and a cast-iron tee with a diameter of 10 cm.Further, drains from sinks and a bath with a diameter of 5 cm are brought to the tee.

At the end of the installation, the plug is removed from the revision, and the riser is sealed by screwing the cover. Thus, the replacement of the water supply riser and sewer pipes in the apartment is over, you can begin to operate the systems.

Replacing a water supply riser in an apartment: do it yourself or call a team

Pros and cons of contacting specialists to replace the water supply riser in the apartment:

• you will save energy, time and nerves;
• almost 100% guarantee of excellent results;
• hiring a foreman or a team is not cheap.

Advantages and disadvantages of replacing a water supply riser with your own hands:

• saving money;
• significant investment of time and effort;
• a quality result is not guaranteed.

Thus, it is obvious that when choosing a method for replacing a water supply riser in an apartment, the price factor can play a decisive role.

Before replacing equipment, you should calculate the cost of consumables, as well as the tools necessary for operation. For example, special devices will be required for cutting polypropylene pipes. Taking into account the purchase of a set of tools, changing the water supply riser on your own will not be cheaper than doing it by hiring specialists.

The cost of replacing a water riser in an apartment

The cost of replacing a water riser in an apartment is the sum of the costs of purchasing materials and paying for the services of workers. If you are going to replace the equipment yourself, but do not have the necessary experience, your costs can increase significantly. So, you can accidentally spoil the neighbour's or common house property and will be obliged to compensate for the damage. As already mentioned, replacing a water riser in an apartment is a time consuming and difficult process, so the slightest inaccuracy can have costly consequences for your pocket.

Below is the approximate cost of all operations carried out when replacing a water supply riser in an apartment:

Name of works		price, rub.
Installation of a water supply riser
Laying PVC sewer pipes (bath, sink, toilet, washing machine)	set
Installing a fan pipe lounger
Installing the fan tee pipe
Installation of a sewer drain
Piping for hot and cold water supply
Fixation of pipes during installation (drilling a hole, dowel, fixing)
Installing a distributor manifold (comb type)
Installation of a valve (ball, valve)
Installation of a tee, coupling, angle, adapter, American connection
Installation of water pressure regulators
Installing the plug on the pipeline
Installation of a non-return valve (plumbing, heating)

Each apartment building has vertical pipelines called risers. As a rule, they are installed in bathrooms.

The distance from the wall is about 5 cm. One riser is used for several water-folding devices, in the lower part there is a shut-off valve.

1 What kinds of riser materials?

The water supply riser in the apartment can be made of various materials:

• steel;
• metal-plastic;
• polypropylene;
• copper.

The first and the last option for self-implementation of the system are very inconvenient. Pipes made of steel are quite problematic to interconnect, and will not allow the use of water for drinking or cooking.

• A polypropylene riser in an apartment building will be inexpensive. Although the installation will require some preparation. A soldering iron is used for the connection. However, the end result is a fast and reliable connection.
• To connect metal-plastic products, special fittings are used. No additional tools needed. And thanks to the flexibility of the material, installation is greatly simplified. True, you need to be prepared for a higher cost than when using polypropylene.

If you need to organize a riser of cold water supply, standard polypropylene is suitable, for hot one you need foil.

Recommendation: if the replacement of hot or cold water supply is carried out, products from the same material should be used. If there are transitions between materials, during operation they can become "weak points".

In the apartments of the old building, there are pipes made of galvanized steel and cast iron. This is not a good option as these materials are prone to leakage, rusting.... Clogging of the material with dirt narrows the inner lumen. This can cause a permanent shutdown of the water supply.

More hot water supply products are susceptible to such clogging.

2 Service life

Basically, these are two cases:

• The pipes have reached the end of their service life. If metal products are used in the system, they are designed to last about 25 years. Of course, in reality, their service life turns out to be much longer, which means that there are risks of complications. When the service life comes to an end, the operation of the pipeline is considered emergency.
• Apartment renovation. Despite the long service life of metal pipes, when a complete renovation is carried out, apartment owners tend to either replace them or move them to another place.

When replacing risers, you should not just cut out the damaged piece of the pipeline, but change it completely, even in ceilings. After all, it is in these places that the greatest wear occurs.

• you must first obtain an official permit to dismantle the old pipeline, for which you need to contact the housing maintenance organization;
• repairs should be coordinated with neighbors, especially during a period when there will be a long cutoff of water;
• disconnection of the existing riser can only be carried out by the master;
• since there are fewer people at home on weekdays than on weekends, work should be done on weekdays. Then the shutdown of the pipeline will be less painful for the neighbors.

2.1 List of required tools for installation

Installation of water supply risers (hot or cold) can be carried out using the following tools and materials:

• Bulgarian;
• puncher;
• keys: gas and adjustable;
• ratchets for threading;
• dye.

If polypropylene pipes are used, you will need a soldering iron, connecting elements.

3 Features of installation

To perform an operation to equip or replace a riser for hot or cold water supply in an apartment building, several stages should be followed:

• drawing up a scheme for finding a water supply system;
• turning off the water supply;
• dismantling of old pipes (if any);
• assemble, install a new rack;
• connecting the water supply to the system of an apartment building;
• installation of accessories: filters, taps and others.

Note that the shutdown of the water supply must be entrusted to the employees of public utilities.

The material must be used as high quality as possible. For hot water supply, it is recommended to use a polypropylene pipe intended for use in the heating system.

For cold water supply, you can use products designed for use as a hot pipeline.

The stages of the work are as follows:

1. After shutting off the water supply, it is necessary to turn off the plumbing fixtures.
2. A grinder is used to cut pipelines. Leave a distance of about 10 cm above the floor and under the ceiling.
3. On the remaining pieces of the pipeline, it is necessary to cut a thread, onto which the FUM tape is then wound, and after them - couplings. These products are selected with a metal inner sleeve and a union nut. The assembly is carried out from below.
4. The pipes should be cut using a special pipe cutter, taking into account the developed installation scheme. The cuts must be at right angles. In this case, the depth of the fitting must be taken into account. Therefore, the length of a piece of pipe should be 3 cm longer.
5. Using a soldering iron, the pipes should be connected.
6. Ball valves should be placed as close to the riser as possible.
7. At the end, piping is done. To fix them on the walls, special plastic clips are used.
8. The holes should be made using a hammer drill.
9. Clips are fastened with plastic dowels and screws.

Replacing risers in an apartment building is a process familiar to most homeowners. When deciding on the installation of new equipment, the property owner should know whose responsibilities include the installation of pipes and at whose expense the procedure is carried out.

Obligations of the owner and the managing organization

The authority to maintain and repair any equipment located in an apartment building is vested in both the owner of the living space and the management company to which the building belongs. It all depends on the place of installation of the elements and devices necessary for the optimal functioning of the building and apartments in it, as well as whether the equipment is common or personal property.

Responsibilities of the managing organization

The service organization is obliged to replace the equipment related to the common property free of charge, since the tenants make a monthly contribution to repair and maintain it in good condition. According to the norms established by the MDK (Methodological manual for the maintenance and repair housing stock), the list of works included in the rent contains:

• maintenance of various common property in the appropriate order;
• maintenance of communication systems;
• emergency work;
• Maintenance.

In other words, any elements of communications used in order to ensure the optimal life of the residents of the whole house must be repaired at the expense of the management office. Moreover, some of them can be located within the apartment.

At the expense of the operating organization, the following equipment is repaired and replaced:

• gas supply pipes to the supply to the stove or heating devices;
• water supply risers before connecting to the piping inside the apartment;
• heating risers up to the junction with the outlet pipes;
• drainage system up to connection with intra-apartment pipes;
• ventilation system;
• power supply system.

In fact, the owner of a privatized apartment pays in advance for the repair and maintenance of all life support systems in the house in advance, paying the set amount prescribed in the monthly receipt. For this reason, employees have no right to demand any additional funds for replacing faulty equipment.

The owner of the privatized real estate is obliged to carry out work to eliminate malfunctions in devices and equipment located within the boundaries of his property. At the same time, there are a number of nuances as to at whose expense the equipment will be replaced. It all depends on whether the device is part of the common property or is in the use of only the residents of the apartment.

Personal property, the troubleshooting of which lies on the shoulders of the property owner, includes:

• gas and electric stoves;
• heating system, in particular, batteries and pipes leading to them;
• electrical equipment such as indoor cable;
• plumbing equipment;
• counters.

In the event of any malfunctions in the equipment related to the common house, the owner of the privatized apartment is obliged to report the violations to the management company in time in order to eliminate them as soon as possible. In a different situation, one or another life support system may fail, which will negatively affect all residents of an apartment building and cause a lot of trouble to a specific owner. In such cases, the owner of faulty equipment often has to pay for the damage caused to other residents as a result of their own negligence in life support systems.

Replacement of risers in a privatized apartment

As for replacing risers in a privatized apartment, everything is quite simple here. The riser is a pipe that runs vertically through all apartments, from the first floor to the last. Serves to provide residents with hot and cold water, gas.

Risers, undoubtedly, belong to the common property, therefore replacement and repair of those are the responsibility of the management company and do not require any expenses from the pocket of the owner of the privatized housing. It should be remembered that on a free basis, only the repair of the riser itself is carried out to the point of its connection with the piping system inside the apartment. This equipment is already considered the property of the tenant, and its replacement occurs at the expense of the latter.

In some cases, employees of operating organizations claim that the repair of risers is the responsibility of the owner and requires additional payment from the owner. This is illegal because the tenants privatized apartments they pay a monthly set fee for repairs and maintenance, respectively, residents of apartments do not have to pay any additional amounts for replacing risers.

Riser replacement procedure

An important point is the appeal of the owner regarding the replacement of a failed operational element. Noticing that the riser is in an unusable condition, the owner should contact the management company as soon as possible and write a corresponding statement. The form will need to indicate information about the observed problems in the equipment, as well as formulate a request for a thorough survey.

During the examination, the company's employees establish the degree of unsuitability of the riser and the need for repair. During the inspection, an appropriate act must be drawn up, including the conclusion of a specialist on the need for repair work, the composition and sequence of such. It also contains information regarding the moment at whose expense the process will be carried out.

The process of replacing the risers is carried out by a company that has entered into an appropriate agreement with the management company. If the equipment belongs to personal property and troubleshooting is paid for by the landlord, the latter has the right to decide on his own who exactly will carry out the repair work in his apartment.

Replacing risers in privatized housing is the responsibility of the management company, since each owner pays a monthly amount to cover the costs of maintaining and repairing all common house operational equipment. When demanding to make additional funds for replacing the riser, the owner of the apartment has the right to apply to law enforcement agencies with a statement, since this is illegal.
