Before starting work on the
Check what the piping needs to replace: bath, toilet, wash( in bathroom and kitchen), bidet, washing machine, etc.
Draw a plan for the new system. It will help to determine everything that is needed for work: the type, length and number of new pipes, types of connecting devices.
Not to be mistaken in the choice of suitable material will help to know some of the subtleties. For example, a toilet pipe should have a diameter of 100mm. Moreover, it is better if it is corrugated: this will simplify the installation much easier. Corrugated siphons for the bathroom and sinks - diameter 32, 40, 50mm. For a washing machine, 20-25 mm is enough.
Professionals advise: purchase all materials from one manufacturer. Thus, installation problems can be avoided when pipes and accessories are fitted.
Check that the necessary tools are available. Are useful: punch, Bulgarian, chisel, hammer, wrench, screwdriver, mounting gun( for sealant), etc. Professionals advise: it is not necessary to buy an assembly gun. It is completely replaced by a hammer: the sealant is squeezed out by the handle inserted into it.
How to clean an old sewer?
Disconnect hot and cold water before use. Wait until the water drains from all plumbing equipment. After that, turn off the plumbing. Release the access to the old pipes: take out of the bathroom everything that interferes with the work.
Pipes adjoining the riser, disassemble. Stepping back from the tee about 10cm, cut off the old pipe with a bulgarian, and carefully remove the remainders or beat them with suitable tools.
The remainder of the pipe is not pulled out? In this case, by its circumference, make incisions with a bulgarian. Tapping gently with a hammer on the chisel located in the notch, split the jammed part. Clean the tee bell well.
After that, on the walls and floors, unevenness is covered with cement mortar and allow it to dry well.
Installation of sewerage in the apartment
During the assembly of the system, experts advise to carry out the work "from the riser" to the plumbing fixtures. The new rubber cuff is already fixed with sealant in the socket of the tee. You can begin the installation.
The installation of the toilet is the most important work. It uses a pipe made of PVC with a diameter of 110 mm. It is important to make a smooth transition to pipes of smaller diameter, using a "bridge" with a diameter of 100 mm. In the direction of drainage, a slope of up to 5 ° is required. It is advisable not to install adapters with an angle of 90 °.It is better to apply two angles of 45o.
Assembly is not difficult: the pipes are inserted into each other using gaskets, which ensure tightness. To achieve a better result, it is better to use a silicone sealant that firmly connects all parts.
Leakage Testing
After the installation is completed, it is important to test the system for leaks. To do this, turn on all plumbing fixtures simultaneously. You can also drastically pour a bucket of water in a bathtub, wash basin or sink.
If leakage occurs, these places need to be reinstalled. Apply special glue-sealant to the problem areas, insert the pipe into the fitting, allow the adhesive to dry. Repeat the leak test.
Observing simple rules, and carefully performing the work with the use of high-quality materials, any owner with his own hands will mount a new sewer.
