Installation began after the construction readiness of the building, ie when all the holes, Stroebe, niches in walls and ceilings, is a mark of pure sex, the walls are plastered areas over which the pipeline will be opened, dug a trench for the issuance and completed all work associated with the use of open flames. Installation of the system starting with the release, then collect the riser from the bottom up, then, from frogs sprue, assemble Floor outlets. Sheaths elements directed towards the flowing stream. Strictly observe the slopes.
A large thermal elongation of plastics makes taking care that the pipelines do not bend during operation. Therefore, when assembling Spigot joints with a rubber gasket between the face of a smooth end of the tube and the base dressed in her funnel leave a gap of 10 mm. He is able to compensate for the thermal elongation of the pipe length to 2 m.
Rubber ring allows you to compensate for misalignment of the attachment. However, very uneven deformation belt sealing ring leads to leaks connections. Therefore, when installation of hidden pipes, especially under the screed, we must see to it that the axis of curvature at the constituent parts of laterals and risers was no more than pipe wall thickness for each meter length of the pipeline. Many companies even make tees with an angle not 90 °, and 87,5 °, so that pipe is laid with a slope, was included into the socket tee, not perekashivaya ring. To avoid damage to the ring for mounting on a smooth tube is inserted at the end make the chamfer and lubricate it with silicone oil, glycerine or soap, but not oils.
Supports open tubes placed more often, for example, on the horizontal – a 0,4 m pipe diameter 50 mm, and vertical – after 1 m, usually under the ground socket. Between metal clamps and pipe supports should be put rubber or plastic pads.
Where it passes through the constructions tube is wrapped 2-3 layers of tar paper or glassine, and the hole sealed with cement to the entire depth.
After assembly of the entire system on its sites experiencing tightness. During the test pressure of 1 atm for 10 minutes, the pressure loss is not allowed. Installation of related areas of hot and cold water to plumbing fixtures are often produced together with the installation of sewerage.
After successful testing of all pipelines are buried Stroebe, holes, niches, make ties and conduct training under the finishing work. Plumbing appliances are usually installed after finishing work.
