Visiting the market, you will be able to find pipes from different materials, namely:
From steel and copper it is best to refuse.This is due to the fact that copper, although it is quite strong and durable, but not suitable for running water, because the quality of water in such pipes can become too low for drinking. As for steel products, they lose to modern polymer options for price, performance and ease of installation.
There is one more factor that causesto abandon the steel pipes, which is expressed in the fact that it is almost impossible to install them independently. The result of all this is that you have to choose between polypropylene and metal-plastic pipes. These options are great for self-installation.
Replacement of the riser in the apartment canprovide for 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 points of connection with time must be checked, since they are weak links in engineering communications.
It is better if the riser is mounted from the pipes of onetype, this will reduce the risk of damage and leaks. If you want to save money, it's better to choose polypropylene pipes, but to connect them you need to master certain skills. You will need to use a special soldering unit. This method allows you to achieve a reliable and lasting connection. If you make a mistake during the installation, you can fix the situation by joining a new section. Polypropylene pipes can be foil. The latter option is designed for installation of a pipeline with hot water.
If replacement of the riser is planned instorey house, then work must begin with obtaining permission to dismantle the water pipe. It can be taken in the housing maintenance service. Tenants of the porch must be warned that the risers are to be replaced. It is important to report the date and time of the water cutoff.
Activities are held on weekdays.Disconnection is carried out by a plumber, which is sent by the housing maintenance service at the agreed time. Replacement of risers of water supply in the apartment with their own hands is better to coincide with the corresponding works throughout the entrance. This will reduce labor costs and reduce the cost of work. If you can not reach an agreement with your neighbors, you will have to install steel pipes, which is not enough for everyone, or mount adapters from metal to plastic by installing polypropylene.
Before you do to replace the riser water supplyin the apartment, it is necessary to draw up a layout for the location of the new water main. 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 pipe is connected to the common system, only after you can start mounting accessories according to the type of filters and cranes.
Disconnection of water supply is carried out by a specialistcommunal service. All plumbing is disconnected, and old communications are cut off from the riser and taken out of the ceiling. With the help of a pipe cutter, it is necessary to cut the pipes in order to obtain lengths of the required length in accordance with the designed scheme. When cutting, it is important to consider the depth of the fitting. To the final value, add 1.5 cm at the ends. This indicates that the calculated length of the workpiece should be greater by 3 cm.
Replacement of the riser in the apartment canprovide for the installation of polypropylene pipes, which are connected with a special soldering iron. To begin with, the master has to select and screw the appropriate attachment to the device. It is heated to 250 ° C. The end of the pipe and the fitting are heated by means of a nozzle. The thermal effect should continue for 10 seconds.
The pipe is connected to the fitting, after thisit remains to wait for cooling. After installing the cranes, you can connect the riser to the water supply system and check for leaks at the connection points. Fastening of the pipe to the wall is carried out by clips, whereas for the installation of the mixer a corner is used.
Instructions for replacing the riser inThe apartment requires the installation of a stop valve at the entrance to the system. It's practical and convenient. If the structure has a faucet, it can be cut to prevent water leakage. The new valve is installed closer to the riser. Work on replacement must begin with inspection of the pipe from neighbors, where it is necessary to carry out the joint.
If the connection is scheduledplastic pipe, then this should not cause difficulties. Use for this purpose a polypropylene soldered coupling. When it is necessary to make a joint with a steel pipe, you need to cut the thread on it to attach the adapter. The structure is inspected for durability.
If the pipe is old or damaged, it is betteruse the services of a specialist who welds the thread, 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 with a collet.
When the repair is overhauled for replacementrisers water supply in the apartment, the work can provide for the transition from metal to plastic. For this, an adapter with an internal thread is used. To seal the connection, you need to apply flax or a tape. The coupling is wound on a steel pipe. With the help of a soldering iron, the plastic part is connected to the pipe and is joined with an adapter. Once you overcome the overlap, you need to solder the tee, from which the wiring will go.
