Sewage plastic pipes gradually replace their less technological predecessors. Today they are quite common in private and industrial construction.
Features of sewer pipes made of plastic
The first and most important property of plasticmaterial for sewage installation is expressed in high quality. Such pipes demonstrate a long service life, but are not very expensive at the same time. In addition, their installation can be done both by a professional in his field, as well as by a home master who does not have an impressive experience in carrying out this kind of work.
Sewer plastic pipes do not assumeuse of special expensive equipment, and after their installation do not need repair for several decades. Plastic products for installation of waste systems are distinguished by impressive chemical resistance, after exposure to corrosive media they remain intact. If you follow all the rules when laying, the system will last for 50 years or more, and you can lay out the described material both outside and inside buildings.
Mounting technology
Sewer plastic pipes are laid inspecific sequence. Initially, it is necessary to stock up with blanks of material, the dimensions of which will correspond to the areas in the room or on the street allocated for installation. After that, you can start laying pipes, connecting them in the process with shaped elements. Once the system is assembled into a single unit, you can proceed to install it in the wall. If a zone has cast-iron pipes, then the plastic bends can be connected to them.
Preparatory work
Sewer plastic pipes can be cut,applying a hacksaw. But it is recommended to use a special tool which, when cutting, allows you to get a chamfer. When carrying out such work manually, the edge of the product should be carefully cleaned, providing an angle of 150 °, this will eliminate the possibility of failure of the sealing ring.
The installation can be carried out using the following materials and tools:
- clamps;
- pipes;
- fitting;
- hacksaw.
Styling
Installation of the elements should be carried out only afterThe way a special lubricant is applied to the smooth end of the components. This rubber gasket will last for a longer time. The smooth edge of the element must be removed from the socket, which will allow the fastening. In order to fix the system, it is necessary to use clamps mounted under the clutch. Horizontally, the pitch between the clamps should not be larger than the diameter of the pipe in tenfold size, as to the risers, this distance is approximately 200 cm. The most suitable step from the elements of the system to the pipe is 4 mm. At installation it is not necessary to make fastening rigid, as it can create internal pressure which is inadmissible.
Sewer in the screed and wall
Before connecting the sewerplastic pipes, you should consider whether it may be necessary to conclude the system components in concrete. At the same time, one should not miss the moment that the design should have temperature grooves whose width is 10 mm. It is important to reliably strengthen the elements so that they do not change their position. The grooves received between the couplings and sockets should be sealed with a scotch tape.
Plastic sewer pipes, the price of whichmay vary depending on the parameters, can be laid in the walls. In the future, they can be hidden under a layer of plaster. In this case, plastic products should be protected, for example, with a corrugated cardboard, but fiberglass is also suitable for this.
Conjugation of polymer and cast iron elements
If you live in an old type building, thenwhen changing the sewage system, there may be a task to connect plastic and cast iron pipes. It is necessary to use a transition branch pipe that has the inner diameter you need. The pairing of polymer and cast iron pipes is carried out by means of a gasket.
The cost of sewer plastic pipes
Plastic sewer pipes, the price ofwhich varies depending on the characteristics, may have a different socket, wall thickness and length. For example, products that have a socket 50 are used when wiring networks that carry household waste. The area of their application is generally quite wide: they are common when installing plumbing fixtures, risers in buildings for any purpose. The described pipes are based on polypropylene gray. Such a material is, on average, 20 times lighter in comparison with analogues made of cast iron. He is not afraid of exposure to hot water to 95 aboutC, as well as chemical agents. Such pipes can have a length of from 20 to 3000 mm, and the price varies from 32 to 156 rubles, respectively.
If you need a plastic sewer pipe100, this means that its diameter will be equal to 100 mm, therefore, you can choose products, the wall thickness of which will be more impressive (2.7 mm), but the price for the same length that was mentioned above will vary within 65 -400 rubles.
Sewer pipes with a diameter of 100mm, designed for the installation of external free-flow systems, which migrate sewage by the method of free flow. These elements are designed for systems that are not subjected to significant loads from the soil.
Before you start laying the drainage system,it is necessary to calculate which plastic sewer pipes and fittings you need, what diameter and characteristics they should have. This will allow you to perform work according to all the rules, which will provide the drainage system with a long lifespan, and you will be freed from the premature need for repairs.
