Often old-built houses are a complete emergency with communications. This is especially true of cast-iron water supply. If the problem is ignored, the result can be disastrous due to flooding of the apartment on the same floor at level 1 inclusive. Need to change communication. In order to replace the water supply riser in the apartment by law, you need to know the basic provisions and principles regarding this procedure.
When replacement of the riser is required
Changing pipes is necessary in such situations:
- Scheduled repair of communications in the house, when the cast-iron plumbing elements have served their purpose. An expiration date of 25 years is shown for them. After 30 years, the system will be in disrepair. Even if the pipes are not damaged externally, this does not mean that the need to carry out repairs can be ignored. Over time, such a riser will present a surprise. Planned replacement of water pipes also applies to the implementation of major repairs in the plumbing room. It is not rational to leave old communications with a completely new equipment.
- Emergency replacement. Such repairs are carried out if fistulas or leaks form in the tubes. Most pipes suffer from interfloor ceilings. Therefore, new elements are joined with the old ones from the residents from below and from above.
If the house is very old, it is advisable to negotiate with the neighbors and completely change the riser from the basement to the exit to the attic. Otherwise, the weak point of the system is shifted from one apartment to another.
Legislation of the Russian Federation
According to the law of the Russian Federation, the riser of each apartment to the valve is the property of the Management Company, Housing Office, OSMD. The property is communal. Responsibility for it lies with the utility. Accordingly, its employees must replace hot and cold water risers in the apartment during major repairs. There is no need for additional surcharges from the tenants of the apartment.
All payments have a column called “Maintenance and repair”. It is for these needs that residents monthly transfer a certain amount of money. Of these, the Criminal Code draws resources for servicing risers, including. Even if there are a lot of malicious defaulters at the entrance, the Management Company has no right to justify this by refusing to replace the water pipes. If, however, the Criminal Code refuses to fulfill its duties, you can first write a statement to the housing inspectorate. And in the absence of a reaction on this side, too, turn to the court.
At his own expense, the landlord only changes the wiring of plumbing networks after the valve. If the shutoff valve in the sanitary room is not provided initially, the remaining pipes are also considered common house property, they are changed by the specialists of the Criminal Code. At this point, you should pay close attention to the occurrence of floods. If the pipe burst to the valve (on the riser), it is the fault of the Criminal Code and it is she who must pay the moral, material damage to the neighbor below. If the fault arose after the valve, the landlord is to blame. With him, and demand.
To attract specialists from the Housing Office or the Criminal Code to carry out the work, the residents of the riser must write a statement. It indicates the essence of the problem and a request for the replacement of worn pipes.
If the pipes are not in disrepair (there was a repair several years ago), then the landlord must agree with the Criminal Code on the possibility of changing the pipes to others.In this case, repairs are carried out at the personal expense of the landlord and only after obtaining written permission from the Management Company. To perform the work, you can invite third-party qualified specialists or use the services of plumbers ZhEKa.
Necessary materials and tools
For work, you need to prepare the following materials and tools:
- Water pipes. It is advisable to take PVC or polypropylene. They have a smooth inner wall, are easy to install, serve 50 or more years. These materials are well suited for both hot and cold water systems.
- Fittings and adapters of the appropriate diameter.
- Stopcock.
- Special couplings, if it is supposed to join pipes from polymer to adjacent metal ones.
- Silicone sealant.
- Pipe cutter or grinder.
- Gas and adjustable wrenches.
- Screwdrivers.
- Hammer and chisel.
- Tape measure, construction pencil.
- Scrap.
In addition, it is recommended to prepare a special soldering iron for polypropylene pipes. Protective equipment will not be superfluous: a hat, glasses, a respirator.
Work on changing the communication is recommended from 10:00 to 15:00. At this time, most of the neighbors at work. The inconvenience of not being able to use water will be minimized.
Before performing repairs, shut off the water. The cost of shutting down the riser is out of the question. Even if the work is carried out in one apartment at the personal request of its owner and in coordination with the Criminal Code, the water is shut off for free.
The sequence of actions when replacing the riser in the apartment
Before changing the riser to water, it is advisable to agree with the neighbors and install new pipes on all floors in one fell swoop. Or at least get permission from the upper and lower tenants to dock new elements in their apartments. If the neighbors do not make contact, you will have to connect the polymer tubes with the metal ones at your floor level and under the ceiling.
Work is performed in the following sequence:
- Overlaps cold and hot water on the riser. The fluid drains from the systems. Disconnect the riser should specialists ZhEK or UK.
- Dismantling of old elements To do this, a grinder makes a cut at a level of 15-20 cm from the floor and ceiling. Long sections are immediately removed. Short - taken out of the floors. If necessary, you can use a sledgehammer to push the settled cast iron.
- If the polymer pipes will dock with the upper / lower metal, then the cast-iron edges are well cleaned with emery.
- Couplings / cuffs are put on the prepared tubes, which will hold the polypropylene or PVC lines. Fittings tighten well with a gas wrench.
- New pipes are lowered through a hole in the floor to the neighbors and joined with the coupling. The same thing is done from above.
- All polypropylene elements are connected using a soldering iron with nozzles. Previously, the ends of the pipes must be treated with a special alcohol composition.
- On a vertical riser make a mark for the formation of branching. At this point, the pipe is cut and made using a tee fitting.
- Be sure to install a shut-off valve before wiring.
The finished system no earlier than an hour later check for leaks. If there are no leaks, the work is done correctly.
If the landlord wants to attract a third-party master to carry out the repair, the price of replacing the water risers will vary from 3,000 to 15,000 rubles. depending on the number of floors involved in the process.
