Major repairs in the toilet and bathroom, residents of city apartments or country houses, in most cases begin with the purchase of pipes, followed by their replacement. This article will talk about the complete replacement of water supply risers in Moscow apartments.

Why is it so important to change risers on time?

If you do not take care of the water supply elements, they can eventually become unusable and cause a lot of trouble to the owners of the living space. We also cannot exclude a situation in which the pipes look normal on the outside, but corrosion and lime have accumulated inside them. It is worth saying that if lime accumulates in large quantities, the diameter of the pipe becomes noticeably smaller. Consequently, normal water permeability suffers from this.

In most cases, old Moscow buildings are equipped exclusively with pipes and risers made of cast iron. Not everyone knows that cast iron is an unreliable material, unlike, for example, PVC. Plus, constant water pressure leads to corrosion and, as a result, leakage. But this is not the most critical situation. Rust in large quantities contributes to the deposition of lime on the walls of pipes, which leads to their complete blockage.

Guarantees:

• All work performed is guaranteed 24 months.
• The materials used have certificates of conformity GOST RF .
• Available all necessary documents for plumbing work.

It is worth saying that it is much cheaper to replace hot and cold water supply risers than to pay for the consequences of a broken pipe. It is necessary to remember that pipes can be replaced not only after they have become completely unusable, but also at the end of the service life of each individual element.

One thing is for sure - if the risers and pipes are not replaced with plastic ones in time, then the owner of the apartment will hardly be able to avoid troubles. Moreover, the problem may arise at the most unexpected moment for the property owner and bring him unplanned financial expenses.

How does the installation of water supply risers begin?

The first thing that needs to be done is to dismantle the old water supply elements. In this case, you need to start with the sun loungers that are located in the basement of the house. But it is possible that in some cases it is simply impossible to do this. In this case, partial removal of old and installation of new water supply pipes is carried out.

Separately, it is necessary to highlight the point that before starting to replace cold and hot water supply pipes in a bathroom or toilet, it is necessary to coordinate the work with the responsible organization. It would also be a good idea to notify your neighbors about the replacement of pipes.

Most people who replace pipes change them exclusively in their apartment. It doesn’t even occur to them that the pipes located in the ceiling may also become unusable. It is for this reason that it is best to make the replacement together with your neighbors.

Who can you trust to carry out plumbing work?

During the complex installation of new risers, one should not forget about replacing related parts. This type of work, performed poorly and by unprofessional specialists, can lead to more than disastrous consequences and additional expenses. Therefore, you need to trust plumbing work to an experienced specialist. Accurate calculations, a highly qualified craftsman, professional equipment and, of course, masterful execution of the task will help you forever forget what pipe leaks and poor water pressure are.

In an apartment building and private building, it has long been common practice for everyone to be equipped with water supply and sewer risers. Already from them there are branching pipes throughout the apartment, which, like vessels in a living organism, supply it with everything necessary and remove the results of vital activity. And if you treat the problems of boners in a businesslike manner, as if they were an organism, then there will be no problems in the house. Given the degree of wear and tear of materials, it is periodically necessary to replace the risers in the apartment.

It is a vertical pipeline passing through all floors in an apartment building. It is necessary for the collection and disposal of waste and used water inside the building. Most often, the material for the sewer riser is cast iron or galvanized steel. In houses whose service life is more than 25 - 30 years, replacing the sewer riser is a prerequisite. Cast iron, like other materials, wears out and rusts over time. And its repair is no longer practical. And the plastic riser has increased fragility. In case of problems, the best solution is to replace the structure.

It is usually installed in the bathroom next to the sewer. The distance between the wall and the riser must be at least three centimeters; there is a system of pipes for water intake and valves.

The water riser, which provides the delivery of cold and hot water in the house, can also be made of galvanized steel and cast iron. Due to corrosion, it is not very practical. In addition to the fact that traces of destruction could appear on the surface, you cannot turn a blind eye to this, since this situation can lead to a leak. In addition, the water passage channel narrows due to dirt and rust getting inside. And here a major overhaul is inevitable.

A problem in cold water supply can lead to interruptions in drinking water throughout the house. And the lack of hot water supply (DHW) will negatively affect hygiene. Unfortunately, hot water risers deteriorate and rust much earlier than cold water. Under all these conditions, urgent replacement of water supply risers is necessary.

Reasons for replacing risers

• emergency condition;
• when it is impossible to repair the sewer riser;
• dissatisfaction with the quality of the material;
• expiration of use;
• renovation and remodeling of the bathroom;
• decreased quality of cold water;
• risk of leaks in hot water supply;
• reduction in water supply capacity.

For those who like redevelopment, there are some problems with moving the sewer riser in an apartment building. Here, it is advisable to coordinate even the replacement with your neighbors.

It would be advisable to carry out renovations on all floors. And if replacing the sewer riser (cast iron with metal plastic or propylene) is in one apartment, then only residents of the top floor can do this without any problems.

In addition, they should carry out the replacement without disrupting the operation of the ventilation pipe water seals. So that in all apartments in the house there is no harmful ventilation. When it is necessary to replace water supply risers, there are subtleties of this action.

It is impossible to change only the problematic fragment of the cold water pipe; in this case, the section from the floor to the ceiling at least within one apartment must be replaced.

To extend the service life of the water supply system, if you need to replace water supply risers, you can use modifications to the hot water pipes when installing a cold water riser. You should not add an insert from another to a pipe made of one material, especially if this is planned to be done before the valves. A combined pipe for both cold and hot water may fail during use. And lead to an emergency. It’s better to immediately change the riser in the bathroom using the same polypropylene pipes.

• Metal-plastic. Good heat dissipation, with the ability to maintain temperature and pressure. As a disadvantage of such pipes, when using cold water, they fog up a lot and require periodic tightening of the collets (due to the narrowing at the junction of fittings and valves), so you should not rush to close the pipes, as they need constant maintenance.
• Cross-linked polyethylene. It is wiser to use for hot water. You can hide it in the wall.
• Polyvinyl chloride. PVC pipes are ideal, if the sewer riser needs to be replaced. Long service life without corrosion. Light weight, easy to install. Connection reliability (tightness).
• Polypropylene. These pipes have the same cross-section in all elements and installation of valves is not a problem; they are well held together by welding. Such pipes are not subject to rotting and corrosion. It is better to choose polypropylene pipes made in European countries rather than Chinese ones.

Replacing all the risers in the house at once is a smart decision. If the time has come to do a major renovation, then changing the riser in the bathroom only for cold water, and leaving the hot water for later, means extending the repair time for an indefinitely long period.

1. Therefore, it is better to do everything in one period. First you need to start dismantling the unusable cast iron riser.
2. The next stage will be the installation of new pipes for cold and hot water. Sewage system connection.
3. Connecting wiring and checking operation.

An important point when replacing a sewer riser is to ask neighbors so that no one in the house temporarily uses the sewer. And he didn’t open the water valves.

Replacing a sewer riser

First of all, this issue should be discussed with the management organization. Professional plumbers will do this job faster and better. But if you decide to do everything yourself, you need to close the door to doubt and start taking action.

• Dismantling.
• Inserting a new riser.

When dismantling, it is worth taking into account the weight of the cast iron pipe, so that when breaking through the ceilings, it does not fall to the floor below, under the weight of its own weight. When installing a new riser pipe, you should start by inserting the lower end of the new riser pipe into the upper end of the downstairs pipe. A rubber gasket must be used in the connection. Do the same by inserting the upper end of the new pipe into the pipe of the next floor.

Replacing the water supply riser

Major repairs of risers begin with drawing up a diagram of the distribution of cold water pipes in all necessary places (bathroom, kitchen, toilet) and preparing the necessary materials.

When replacing cast iron pipes with those made of polypropylene, you can count on an environmentally friendly and durable water supply design. The plastic version will also be a little inferior here. When installing cold water, polypropylene pipes are chosen due to their resistance to corrosion and the smoothness of the inner surface (limescale does not accumulate).

When replacing hot water pipes, it is better to use pipes made of cross-linked polyethylene; it is more resistant to high temperatures. Then there will be a chance to close the issue of re-repairing the water supply for a long time.

What do we have to do:

1. Resolve the issue with the management company and neighbors that the apartment will undergo a major water supply repair.
2. Be sure to close the taps before dismantling. Shutting off the valves is necessary so that there is no interference during work. Dismantle the old cold water system.
3. Plan the layout of a new section of cold water. Attach pipe holders to the wall.
4. Cut the pipes, cleaning the areas of intended soldering with alcohol.
5. Solder the cut pipes using a Teflon nozzle, heating the device to 250 degrees. The pipe and fitting must be put on the device at the same time, then after heating they are easily connected.
6. When connecting to a cold water riser coming from neighbors, use a coupling. If the risers are made of different materials, you need a coupling - an adapter.
7. After assembling the entire system, open the tap and check the tightness. If there is a leak, close the valve again and correct the problem.
8. Just in case, you shouldn’t hide the new riser, completely blocking access to it. There are situations where this may prevent problems from being fixed quickly.

Repairs in an apartment, especially in old houses, often begin with the replacement of such parts of plumbing communications as: heating pipes, sewer risers. The homeowner will not ignore the water supply risers. After all, you want everything in your apartment to be sparkling clean after renovation, but rusty old pipes can ruin the whole appearance. However, replacing water supply risers in an apartment is not such a simple matter. And most of the problems in carrying out this work are far from technical.

Who should carry out this work?

To answer this question, one should turn to the legislation of the Russian Federation and, first of all, to the Housing Code, which regulates all issues related to living in apartment buildings and their renovation. So, according to Article 161 of the Housing Code of the Russian Federation, all work on replacing and repairing water supply risers in any apartment must be carried out by the management company to which the residential building is assigned and which receives the same payments transferred monthly for utility bills. By the way, in the payment document there is a column called “Maintenance and routine repairs.” This is exactly what the replacement of water supply risers in apartments is suitable for (even despite the fact that the housing is registered as a property).

And if the issue of replacing the water supply inside the apartment is decided (as they say, “to the valve”), then all the costs are borne by the homeowner. And this aspect is very important in such controversial issues as, for example, flooding of neighbors. If the water supply breaks, the owner is to blame, and if the flood occurred due to the destruction of the riser, then the management company is to blame. In the latter case, she is obliged to compensate for all damage to the victims.

Note! When the management company refuses to change the risers, citing the fact that “there is no money,” and invites residents to decide the issue of financing themselves, you should not fall for this trick. You need to file a complaint with the housing inspectorate and under no circumstances seek money on your own.

Moreover, if the building has apartments with persistent defaulters, then the management company has no right to rely on this and abandon its responsibilities. You can even force her to carry out the required work through the courts.

It is worth remembering that all of the above information applies specifically to apartment buildings. In a private house, only the owner should change the risers.

When do you need to change risers?

Risers can be replaced in two cases.

1. Planned replacement, which must be carried out as soon as the service life of the plumbing equipment has expired. The guarantee of trouble-free service of a metal water pipeline is 25 years, and after 40 years of use, the pipes are recognized as emergency.
2. Unscheduled emergency replacement, which is carried out if an emergency (leak) occurs in the house regarding water supply risers.

Even if the pipes look intact, strong, and reliable, after their service life has expired, you should not use them and rely on their apparent reliability. A water pipeline that is in this condition can easily leak and destroy all repairs for both neighbors and apartment owners. , You can read in our article.

It is also recommended to change the risers at a time when a major renovation of the apartment is underway. The fact is that in this case, water conduits are often hidden behind decorative panels or in walls, and this greatly complicates access to them. Therefore, it is better to be sure that the risers are in excellent condition.

Where does work begin?

Work to replace water supply risers does not begin with the purchase of new pipes, but with coordination of the work with the management company and other residents. The first step is to contact the housing and communal services department and submit an official application there demanding that the water pipelines be replaced. In this case, the document must indicate valid and not far-fetched reasons (for example, an emergency condition, wear and tear of equipment). The application should also be supported by evidence - for example, photographs or the results of an officially conducted examination. The application must be submitted in two copies, one of which will remain in the applicant’s hands and (necessarily!) with a note that it has been accepted. If a replacement is truly necessary, the management company must respond quickly. If anything, the applicant will receive a document explaining all the reasons for refusing to carry out the work.

Step 1. In the basement, the water supply to both hot and cold water supplies is shut off. The pipe water comes down from the pipes. This is done by the employees of the management company.

Step 2. The space for work is being prepared - if necessary, the toilet is removed, all kinds of bedside tables are moved away, decorative walls are dismantled. After this, the old pipes are dismantled - they are cut with a grinder approximately 20-30 cm from the level of the ceiling and floor.

Step 3. Now the neighbors below and above the floor are also cutting off the riser pipes - this will make it possible to pull the pipe sections through the ceilings.

Step 4. The cut edges of the pipes are cleaned of burrs.

Step 5. At the junction of old pipes with new ones, special coupling connectors and clips are put on to hold them. All elastic bands are tightly fixed at the desired level.

Advice! A gas wrench will help tighten the connectors.

Step 6. A pipe of the required length (enough to connect the riser into a single system again) is lowered through a hole in the floor to the downstairs neighbors.

Step 7 Using a special nozzle and a heater, the polymer pipe and connector are heated and connected at the junction. The pipes of the neighbors on the higher floor are also connected.

Step 8 Two pipes coming from the neighbors below and above are connected in the owner’s apartment using the same heater.

Step 9 Marks are made on the pipe in the place where it is necessary to make a branch to supply water to the bathroom or kitchen. The pipe is cut at this point.

Step 10 The branch is also connected to the riser. The work has been completed. Before the riser is put into operation, the tightness of the connections should be checked.

It is worth remembering that replacing risers is a very responsible undertaking, and all work must be carried out carefully and carefully. It is also undesirable to move the risers to another location or change their shape without permission, that is, without the permission of the management company. After completing the work, you should make sure that there is still access to the pipes, despite the decorative decoration of the room - you can make beautiful doors or special hatches. But you cannot cover the water pipes with tiles - in the event of an accident it will come out sideways.

Major renovation of an apartment is another reason to replace the water supply riser

Let's start with what are hot water supply and cold water risers? These are hot and cold water pipes that run vertically through a plumbing cabinet in a bathroom or kitchen.

Replacement of water supply risers is carried out in cases where:

• pipes have exhausted their service life or are in disrepair. Most often, water risers are made of steel, and their main enemy is corrosion, which leads to the formation of fistulas. In addition, rust and dirt clog the pipes from the inside, which makes it difficult for water to pass through;
• A major renovation of the bathroom is being carried out, since after the “finishing” finishing, access to them will be limited. In the future, if there is a need to replace or repair pipes, dismantling the plumbing cabinet will not be avoided;
• the location of the heated towel rail changes, for example, moving it from under the washbasin to the opposite wall of the bathroom. To maintain its efficiency, a bypass device or re-connection of the hot water riser is required;
• I want to increase the area of ​​the bathroom. Re-cutting the hot water and cold water risers, pressing them against the back wall, will reduce the size of the plumbing cabinet and increase its functionality (see article).

Attention! The risers are common property, so any redevelopment must be agreed upon with the Management Company.

Who should change the hot water and cold water risers?

In cases where the pipes are in disrepair, the replacement of hot and cold water risers in apartment buildings should be handled by the Management Company, since the risers are the common property of the building. Here it is worth clarifying the boundaries of operational responsibility. In a privatized apartment, the Management Company is responsible for communications to the shut-off valve, and then the owner of the apartment.

But in practice, utility workers only make minor repairs, and there is no hope of completely replacing the risers. If you decide to do a major overhaul and there is a need to replace the risers so that they do not disturb you in the future, the answer is clear: the replacement will be made at your expense. The same applies to sewer pipes.

It is better to invite qualified craftsmen to replace the risers. This will reduce time and effort, and will more likely guarantee the quality of the work done.

Which pipes to choose: steel or polypropylene?

Steel pipes for water supply have been used for a long time. Now, with the abundance of much more modern materials, it seems that the material has outlived its usefulness. But many people still choose this traditional option. The advantages of such pipes include:

• the mechanical strength of the product and pipes can withstand both external and internal loads equally well;
• price;
• low ability to deform when heated;
• large selection of any compatible fittings.

Flaws:

• susceptibility to corrosion if the pipes are not galvanized;
• decrease in pipe lumen over time;
• condensation formation contributes to premature wear;
• complex installation;
• a steel pipe changes the taste of water.

Polypropylene pipes are the exact opposite of their metal counterparts. This option has many advantages:

• pipes are resistant to corrosion;
• material strength - pipes last for several decades without requiring replacement;
• the smooth inner surface does not contribute to the accumulation of deposits;
• plastic has good noise-absorbing properties, which is important for indoor wiring;
• weight is significantly less compared to metal pipes;
• simple installation process;
• polypropylene pipe does not change the taste and composition of water.

As with steel pipes, polypropylene pipes have their drawbacks:

• temperature regime - intolerance over 95°C;
• low resistance to deformation under mechanical load.

When choosing pipes for future risers, you need to start from the source material. If the material is heterogeneous, unnecessary stress may arise, because they have different physical properties. Important! The installed pipes must be the same diameter as the previous ones. Otherwise, the operation of the general house water supply system will be disrupted.

Joint connection methods: threaded or welded?

The main method of detachable connection of steel pipes is the threaded method. If installation rules are followed, it provides good strength and tightness. This method is used if it is necessary to switch to a different diameter, for connecting at turns, for lengthening and branching. Convenient to assemble and operate, as well as for repair or modernization. If it is necessary to replace plumbing fixtures, it does not require special equipment.

Welding is a method of permanently connecting pipes. Most often, a butt welded connection is used due to its increased strength. Effective performance of welding work guarantees the absence of fistulas and other defects.

Features of preparatory work.

When replacing hot water and hot water risers, you will need to turn off the water supply. The shutdown is carried out by utility workers. It is better to plan a shutdown for the middle of a weekday in order to cause as little inconvenience as possible to other residents of the house.

Also, before starting work, it is worth agreeing with the neighbors living in the apartments above and below about the possibility of performing work on their territory. This is necessary so that new pipes pass through the ceilings. If the neighbors do not agree, then the riser needs to be changed only within the boundaries of your apartment - from ceiling to floor.

Sewerage. Reasons for replacement. What happens (Cast iron, PVC, HDPE).

It is better to combine the replacement of the sewer riser with the replacement of water pipes, so as not to re-dissolve dirt in the apartment. In addition, this will allow you to save money, because all the work will be done at the same time and you will not have to pay for turning off the water again.

Reasons for replacing a sewer riser:

• emergency condition of the pipe (cracks, blockages);
• redevelopment. Relocating a toilet or bathtub, at a minimum, requires replacing the crosspiece or tee;
• installation of plumbing fixtures at standard heights. Replacing the sewer riser with lowering the level of the outlets will eliminate the need to install various podiums for the shower stall and toilet;
• lowering the floor level. In many standard plumbing cabins, it is possible to lower the floor level below the general apartment level. To install plumbing fixtures at a standard height, you will need to lower the sewer outlet.

The question remains which pipes are best for sewerage, because their range is wide, and the sewerage system should serve reliably and for a long time. Cast iron pipes. Such pipes have been used for quite a long time. They are characterized by durability, strength and good sound insulation. Disadvantages include cost, heavy weight and, as a result, difficult installation. In addition, over time, a build-up forms on the inside, which complicates the drainage of liquid. Plastic pipes provide good sewage functionality. The advantages of such pipes include a long service life, low cost, and light weight. The smooth surface of the pipes ensures that there is no build-up. PVC pipes (polyvinyl chloride) are used to a greater extent for gravity-type sewers. They are characterized by high strength and good resistance to mechanical damage, and can also withstand temperatures of 70°C. But the fact of exposure to chemicals, aggressive detergents and high-temperature liquids negatively affects the condition of the pipes, the walls are damaged and plaque appears, which then turns into a blockage. As opposed to PVC pipes there are HDPE pipes (low pressure polyethylene). They have high chemical resistance, but low impact resistance. They are allowed to operate at temperatures not exceeding 50°C. They are not subject to internal fouling by microorganisms, and their throughput does not decrease during operation. To summarize, it is worth noting that PVC sewer pipes are gradually replacing their analogues from our homes, because they have high performance characteristics and provide a high-quality wastewater disposal system for many years.

If you have been living in your apartment or house for quite some time, you must have encountered the problem of leaky pipes. When replacing the water supply riser in an apartment becomes an urgent problem, you must try to solve it as quickly as possible, because otherwise you may encounter a leak.

Theoretically, the consumer should not carry out such work on his own if he uses housing and communal services, but in reality everything is different. Therefore, it is better to do it yourself when replacing pipes.

Pipe selection

By visiting the market, you can find pipes made of different materials, namely:

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

It is best to avoid steel and copper ones. This is due to the fact that copper, although it is quite strong and durable, is not suitable for plumbing, because the quality of the water in such pipes may become too low for drinking. As for steel products, they are inferior to modern polymer options in price, performance characteristics and ease of installation.

There is another factor that forces you to abandon steel pipes, which is that it is almost impossible to install them yourself. The result of all this is that you have to choose between polypropylene and metal-plastic pipes. These options are great for DIY installation.

Replacing the water supply riser in an apartment may involve the use of metal-plastic structures, which are reliable and allow connection without the use of additional tools. Such pipes are quite flexible, but the cost of construction can be quite impressive. The connection points must be checked over time, as they are the weak links of utility lines.

It is better if the riser is mounted from pipes of the same type, this will reduce the risk of damage and leaks. If you want to save money, it is better to choose polypropylene pipes, but to connect them you need to master certain skills. You will have to use a special soldering unit. This method allows you to achieve a reliable and durable connection. If an error is made during installation, the situation can be corrected by connecting a new section. Polypropylene pipes can be foil-lined. The last option is designed for hot water.

Where to start

If it is planned to replace the riser in a multi-storey building, then work must begin with obtaining permission to dismantle the water supply system. It can be obtained from the housing maintenance service. Residents of the entrance should be warned that the risers are to be replaced. It is important to communicate the date and time the water supply is turned off.

Events are held on weekdays. The disconnection is carried out by a plumber, who is sent by the housing maintenance service at the agreed time. Replacing the water supply risers in an apartment with your own hands is best timed to coincide with the corresponding work throughout the entire entrance. This will reduce labor costs and reduce the cost of work. If you fail to reach an agreement with your neighbors, you will have to install steel pipes, which not everyone is happy with, or install adapters from metal to plastic by installing polypropylene.

Work order

Before you start replacing the water supply riser in your apartment, you need to draw up a diagram of the location of the new water supply. At the next stage, the water supply is turned off, the old pipes are dismantled, and then a new riser is assembled and installed. The water supply is connected to the general system, only then can you begin installing accessories such as filters and taps.

The water supply is turned off by a utility service specialist. All plumbing is disconnected, and old communications are cut off from the riser and removed from the ceiling. Using a pipe cutter, it is necessary to cut the pipes to obtain sections of the required length in accordance with the drawn up diagram. When cutting, it is important to consider the depth of the fitting. To the final value you need to add 1.5 cm at the ends. This suggests that the estimated length of the workpiece should be 3 cm longer.

Replacing the water supply riser in an apartment may involve the installation of polypropylene pipes, which are connected with a special soldering iron. To begin with, the technician will have to select and screw a suitable attachment to the device. It is heated to 250 °C. The end of the pipe and the fitting are heated using a nozzle. The heat exposure must continue for 10 seconds.

The pipe is connected to the fitting, after which it remains to wait for it to cool. Afterwards, you can connect the riser to the water supply system and check for leaks at the connection points. it is attached to the wall using clips, while a corner is used to mount the mixer.

Instructions for carrying out work

The instructions for replacing the water supply riser in an apartment require the installation of shut-off valves at the entrance to the system. It's practical and convenient. If the structure has a tap, it can be cut off to prevent water leakage. The new tap is installed closer to the riser. Replacement work must begin with an inspection of the pipe from the neighbors where the joint will have to be made.

If the connection is planned to be made with a plastic pipe, then this should not cause difficulties. For this you need to use a polypropylene solder joint. When it is necessary to make a joint with a steel pipe, you need to cut a thread on it to attach the adapter. The structure is inspected for strength.

If the pipe is old or damaged, then it is better to use the services of a specialist who will weld the threads, otherwise you may encounter cracks on the surface from the load. Experts recommend cutting or welding about 6 turns. You can also consider the option of connecting using a collet coupling.

Sealing joints

When a major overhaul is carried out to replace water supply risers in an apartment, the work may involve a transition from metal to plastic. For this purpose, a transition coupling with internal thread is used. To seal the joint, you need to use flax or fum tape. The coupling is screwed onto a steel pipe. Using a soldering iron, the plastic section is connected to the pipe and joined using an adapter. As soon as you overcome the ceiling, you need to solder a tee, from which the wiring will go to the apartment.

Replacement of risers according to the law

If you are interested in the law on replacing water supply risers in an apartment, then you should know that, according to Article 161 of the Housing Code of the Russian Federation, all work is carried out by the management company to which the residential building is assigned. But if the issue of replacing the water supply inside the apartment is decided, then all costs are borne by the owner of the property. This aspect is extremely important in case of controversial issues such as flooding of neighbors.

If the water supply fails, then the owner is to blame, whereas if the flood was caused by the destruction of the riser, then the management company will deal with the problem. The management company should not replace the water supply risers in the apartment. However, if its specialists refuse to change the risers of the house, citing insufficient funds, then the issue must be resolved by filing a complaint with the housing inspectorate.

Cost of work in Saratov

If you do not plan to replace the risers yourself, then you can use the services of specialists. Using polypropylene pipes, the diameter of which varies from ½ to 1¼, the work will cost from 2,500 rubles. If you have just moved into a new apartment and steel risers are installed there, then after two years of their use there is a risk of them becoming overgrown. Experts advise replacing water supply risers in an apartment; in Saratov, experts offer their services at an affordable cost.

Finally

Such work may also be necessary if the apartment has low water pressure. As the flow intensity decreases over time, you may notice that a thin stream begins to flow from the tap. This pressure will not be enough to start the washing machine. In this case, a decision should be made to replace the pipes.
