For the installation of sewer pipelines in the last century, several types of pipes were used. Usually these were concrete or cast-iron pipes, and ceramic ones were used much less often. At the moment, PVC sewer pipes are especially popular . What is this material and how to work with it?
PVC sewer pipes: benefits of using
Polyvinyl chloride is a polymer widely used in repair and construction. This material is characterized by amazing physical and technical qualities and a minimum of flaws. Such widespread use of products from this substance is due to the fact that it is harmless to human health. When heated, the material does not exhale harmful gases, it is not combustible, and working with it, in general, is a pleasure. Among developers, PVC sewer pipes are in great demand, which pretty much displaced products made from traditional materials. This is due to a number of advantages:
- a high degree of strength, as well as a sufficiently long service life;
- low weight, which makes their loading and installation easier;
- the connection is a very simple process that does not require the purchase of any special equipment;
- a high degree of resistance to the influence of aggressive environment, ultraviolet radiation and temperature;
- excellent throughput, as well as the possibility of self-cleaning;
- PVC sewer pipe (150 mm in diameter) is clogged much less than a similar cast-iron pipe.
Another advantage can be called the fact that after their installation does not require staining or other additional method of protection against the effects of various external factors. The presence of chlorine atoms in the composition promotes self-extinguishing in case of fire, and this allows you to eliminate the fire quickly enough.
Sewer PVC pipes: varieties
The industry produces several groups of such products. You can call these varieties:
- focused on the creation of indoor systems;
- intended for use outside buildings and structures;
- oriented to use in pressure sewer systems.
Mounting Features
The first stage of work requires a detailed project. To do this, calculate the number of conclusions that must be installed. This number is determined by counting the water discharge points. Typically, this amount includes a kitchen sink, shower or bathtub, toilet, washbasin in the bathroom, washing machine and dishwasher. Each drainage point requires the use of an oblique tee. In this case, it is inappropriate to use straight lines, as this can adversely affect the speed of water movement. After that, the length of the pipes is measured, for which you can use tape measure.
The connection of the elements is made in the bell. If you use a sewer PVC pipe of 250 mm (diameter), then all tees must be of the appropriate diameter.
