Even a decade ago sewerage improvement occurred with metal santehtrub. Practice has shown that this material is not practical, since the corrosion resistant. On the inner surface of the product is collected: silt, dirt, clumps of oil. Clean such blockages difficult.
The new generation of sewer pipes - plastic or PVC. High-tech product. On the basis of PVC santehtrub created sewerage scheme in a city apartment and the local system outside the city: at the cottage or country house.

Types of plastic pipes for sewers
Such drainage is not so complicated and so private owners hesitant to install it yourself. Some species are assembled without the use of soldering tools, special expensive devices, which simplifies installation.
Carefully read the instructions on the Internet, it is possible to assemble a circuit which will last 50 years. So much exploited PVC materials that are based on polyvinyl chloride.
divided: as intended, the diameter size.
Are used inside and outside the premises. For urban apartment suitable internal models. For local suburban sewage fit model, labeled for outdoor use.
In no case can not be installed inside the building the kind that is designed for the outdoor and vice versa
Domestic gray in color. In case of incorrect installation of a loud and unpleasant noise. Heat-resistant products are coated with a special protective solution, which prevents silting of the interior space and clogging the pipes.
Sanitary materials with improved structural characteristics are colored green tint.
Products intended for outdoor use, painted in red color, which resembles the shade of red brick. Such constructions are connected together, carry heavy loads. They are specially designed for underground installation. Not afraid of sudden changes in temperature, frost, freezing system.
For internal wiring mounted santehmaterialy diameter: 32, 40, 50 and 100mm. PVC products, that is exploited outside has typical dimensions: 100, 150, 200, 250 and 300mm.
destiny
When installing the applicable straight parts of different sizes and diameters and indirect: elbows, bends, tees, crosses, reducers, couplings.
Made of high quality plastic:
- having a long life,
- does not crack during the operation,
- not coming down ahead of time,
- if necessary, be repaired or partial replacement.
Turns required for the installation direction of the gasket components. Such products are created in several different ways: at 15, 30, 45 and 90 degrees.
Taps made in direct and oblique design. Products are used to connect the porcelain toilets in the house.
Joints experts often refer to repair. In keeping with its name, they are repaired two parts of the pipe not having sockets.
When installing a new sewer system does not use the clutch better. They are only suitable for repair of sewer products.
Adapters - small sections of pipesThat connect them to each other and of different diameter pipes.
Crossings operated outlet lines branching in several directions simultaneously. Parts can be in different planes and more tubes are arranged from each other by 180 degrees.
In addition to the component parts of the sewer schemes are used: Audit plug, check valve, special clamps for attaching articles together.
Under the Audit plug refers to the special PVC caps covering unused sewer issues. Closed at the time of inspection hole - a good thing, which is used in case of blockage.
Mini hatch - ability to effectively clean the beds sewage. This is the same tees that the branch (one of them) is plugged. If necessary, it opens.
The check valve controls the flow of sewage and prevents their flow in the reverse direction. Clamps are attached to the ceiling and the floor, the wall - mounting sewerage scheme.
Pros and cons of plastic pipes for sewers
Advantages:
- elasticity;
- susceptibility to diffusion welding, which allows to glue PVC products;
- low thermal conductivity;
- strength to operate the high-pressure system, but no more than 10 atmospheres;
- resistance to low temperatures (minus 65 degrees Celsius);
- resistance to high temperatures (up to plus 90 degrees Celsius);
- resistance to frost;
- Immunity to ice, which pushes the morning diameter PVC link.
For products high tightness of the joint and the relatively low cost in comparison with metal sewer systems.
In the case of extreme operating sewage system - PVC sostavlyuschie not break, they did not crack, do not come down in a year or two after the start of operation. The materials can be used in hot water supply systems, if the pipe assumes drain preheated water.
Have a low specific gravity, the surface is not susceptible to the effects of household chemicals. In tech design high bandwidth, so the likelihood of clogging is minimized. Plastic parts are glued together using a special apparatus, which is inexpensive.
Disadvantages include polyvinyl chloride noise during operation of the system. Water with a roar merges the riser. Softened PVC construction, if the liquid temperature exceeds 90 degrees Celsius.
malfunctions
If not complied with the incline level, sewer system and outflow of sewage / waste water is difficult - often caused traffic jams. Need cleaning.
For faults are:
- blockages
- water seal
- damage to pipelines
- Mechanical damage
- Excessively noisy work
If the design has been accidentally damaged mechanically, needs repair punched portion with complete replacement of part or restoration of integrity with a special tool.
Professionals who come a call for eliminating congestion, the method used chemical and mechanical cleaning, water pumping, cleaning using the hydraulic locks.
The owners are often on their own can recover the system by using the inspection door, closed flap. This is an unpleasant procedure, but the operation of the circuit is restored quickly, because the blockage is removed.
Transport and Storage
Transportation, loading and unloading of products necessarily conducted at a temperature not lower than minus 10 degrees Celsius. Transportation at negative air temperatures is only allowed when using specialized facilities, fixing the product. This allows you to safely load and unload goods.
Composite plastic parts for sewage protect from shock and mechanical stress. The surface of the constitutional units must not be scratched, pierced metal tool. When transporting pipe necessarily stacked on the flat surface of the transport platform.
Materials are stored in unheated sheds, buildings, premises. Do not put any structural elements closer than one meter from the heating radiator or other heating element mounted on the stock. Pipes have to remove from the sun, rain, snow (precipitation).
