If you've been living in your apartment or house for a long time, you must have experienced the problem of leaky pipes. When replacing a water riser in an apartment becomes an urgent problem, it must be solved as quickly as possible, otherwise you may encounter a leak.
Theoretically, the consumer should not independently carry out such work if he uses the utilities, but in reality everything is different. Therefore, it is better to do it yourself by replacing pipes.
Pipe selection
By visiting the market, you can find pipes made of different materials, namely:
- polypropylene;
- steel;
- copper;
- metal plastic.
It is best to refuse steel and copper. This is due to the fact that copper, although quite strong and durable, is not suitable for plumbing, because the quality of the water in such pipes can become too low for drinking. WhatAs for steel products, they lose to modern polymer options in terms of price, performance and ease of installation.
There is another factor that makes steel pipes to be abandoned, which is expressed in the fact 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 a water riser in an apartment may involve the use of metal-plastic structures that 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. Connection points need to be checked over time, as they are weak links in engineering communications.
It is better if the riser is made 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, however, 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, then the situation can be corrected by attaching a new section. Polypropylene pipes can be foil-coated. The last option is for hot water piping.
Getting Started
Ifreplacement of the riser is planned to be carried out in a multi-storey building, then work must begin with obtaining permission to dismantle the water supply. It can be taken 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 of the water cutoff.
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. Do-it-yourself replacement of water supply risers in an apartment is best timed to coincide with the corresponding work throughout the entrance. This will reduce labor costs and reduce the cost of work. If it is not possible to agree with the neighbors, then you will have to install steel pipes, which does not suit everyone, or mount adapters from metal to plastic by installing polypropylene.
Work order
Before you start replacing the water supply riser in the 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 after that you can proceed with the installation of 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 in order to obtain segments of the desired length in accordance withdrawn up scheme. 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 a 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 master will have to select and screw a suitable nozzle to the device. It is heated up to 250°C. The end of the pipe and the fitting are heated with a nozzle. The heat exposure should continue for 10 seconds.
The pipe is connected to the fitting, after that it remains to wait for cooling. After installing the taps, you can connect the riser to the plumbing system and check for leaks at the joints. The pipe is fixed to the wall with clips, while a corner is used for mounting the mixer.
Work instructions
The instruction for replacing the water supply riser in the apartment provides for the need to install shutoff valves at the entrance to the system. It's practical and convenient. If the design has a tap, it can be cut off to prevent water leakage. The new crane is installed closer to the riser. Replacement work must begin with an inspection of the pipe at 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. It is necessary to use a polypropylene solder sleeve for this. When it is necessary to connect withsteel 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, it is better to have a specialist weld the threads, otherwise you may experience stress cracking on the surface. Experts recommend cutting or welding about 6 turns. You can also consider the option of connecting with a collet coupling.
Joint sealing
When a major overhaul is carried out to replace the water risers in the apartment, the work may involve the transition from metal to plastic. For this, an adapter with an internal thread is used. To seal the connection, 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 overlap, you need to solder the tee, from which the wiring will go to the apartment.
Replacement of risers by law
If you are interested in the law on the replacement of 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 plumbing inside the apartment is being decided, then the owner of the home will bear all the costs. This aspect is extremely important in controversialquestions about the type of flooding of neighbors.
If the liner is out of order, then the owner is to blame, while if the flood was caused by the destruction of the riser, then the management company will deal with the troubleshooting. Replacing the water supply risers in the apartment by the management company should not be carried out. However, if its specialists refuse to change the risers of the house, referring to insufficient funds, then the issue must be resolved by filing a complaint with the housing inspectorate.
Cost of works in Saratov
If you do not plan to deal with the replacement of risers yourself, then you can use the services of specialists. With the use of polypropylene pipes, the diameter of which varies from ½ to 1¼, the work will cost from 2500 rubles. If you have just moved into a new apartment, and steel risers are installed there, then after two years of their operation there is a risk of their overgrowing. Experts advise to replace the water supply risers in the apartment; in Saratov, specialists offer their services at an affordable cost.
In closing
Such work may be needed even if the apartment has low water pressure. As the flow rate decreases over time, you may notice that a thin trickle has begun to flow from the tap at all. This pressure will not be enough to start the washing machine. In this case, a decision should be made to replace the pipes.
