The sewer system is a necessary element of comfort in a private house or in the country. It performs important functions of cleansing the home from odor and impurities. Poor piping installation can cause blockages and unpleasant odors.
Not everyone knows how to install sewer pipes. Most entrust this work only to professionals.
But, observing the technology, the sewage system can be equipped with your own hands.
The main difficulties lie not only in the specificity of installation work, the correct selection of materials, equipment and components, but also in compliance with the rules and regulations.
The main sewerage mechanism is the natural (non-pressure) waste flow through pipes. Correct installation is carried out with a slope of 2-15% to the internal pipeline, external sewerage and septic tank. The exact angle is determined individually.
For these purposes, special tables are used with average values for plumbing fixtures and pipes of different lengths and diameters. The slope of the pipes is fixed with brackets attached to the walls.
It is often impossible to create the desired pipe slope in the basement and in the basement. For this, pumping equipment is installed.
There is a certain norm for the ratio of pipe diameters: the difference between the pipe diameter at the point where the plumbing fixtures are connected to the sewerage system and between the pipe diameter that goes into the septic tank should be 2-15 cm.
Universal pipe diameters for different sections of the sewer system:
According to the rules of installation, pipes are insulated by wrapping them with glass wool or fiberglass, covering with polyethylene.
Ventilation - regulates the pressure and vaporization of gases during the flow of waste water. For this purpose, ventilation hatches, wells, valves are installed in the internal and external sewage system.
If there are several collectors in the house, ventilation must be provided in all.
Ventilation is brought out through the walls and roof.
If the length of the connection between the pipeline and the toilet is more than 1 m, and all other plumbing fixtures are more than 3 m, they must be equipped with an additional ventilation pipe that carries gases out through the roof.
Parts of internal sewerage:
The reliability of pipe connections in the sewage system affects the durability of its service. Carefully study the characteristics of pipe materials, types of connections, materials and elements that you need. These are various tees, adapters, couplings, crosses, fittings and parts of bends that connect pipes.
Pipes of different materials can be used for installation. The most popular are plastic and cast iron. Moreover, the latter are capricious in care and laborious to install. Therefore, plastic is most often installed. Plastic differs from cast iron and metal products in that it does not burst, does not corrode and is light enough.
Typically used for sewerage systems:
It is also necessary to master the methods of joining pipes made of various materials:
First, decide which devices and where you will install. Make a plan, think about what components are required for the normal operation of the devices. Calculate all sizes.
You may need:
Often, special tools and devices are required to cut such pipes. Poorly cut and uncleaned ends leave gaps in the joints, allowing household waste to seep.
Tools used for cutting plastic pipes:
It makes the cuts neat, chipping free, without bending the pipe. The roller adjusts the tightness of the connection of its cutting sections to the pipes. The disadvantage of a pipe cutter is the need for a large work space. If you need to cut a pipe arranged near a wall, he will have nowhere to turn around. For such sections, single-pass pipe cutters are used.
Its task is to remove the edge of the pipe ends to improve adhesion during their welding. Manual bevellers can work with pipes 40 - 300 mm.
Moreover, each calibrator only works with a certain pipe diameter.
For the correct connection and laying of plastic pipes, it is important to keep in mind the peculiarities of their installation, for example , then that:
We hammer it 2/3 into the cracks using a spatula made of wood;
The most important part of the work is the toilet bowl device. We connect it to the sewage system using a plastic pipe with a diameter of 110 mm. Then we make a smooth transition to the 50 mm pipe. To do this, use a short bridge of 100 mm, then go to 50 mm.
Do not use right angle adapters. It will be more competent to use two 45 degree adapters.The pipes are joined through gaskets, but it is better to additionally use a silicone sealant.
