When replacing a cast-iron sewer with a plastic one in an apartment building, it is necessary to warn neighbors and cut off the water supply. Previously, a plan should be made taking into account all pipe segments and fittings, to determine the method of joining and sealing of the system elements.

It is better to plan the withdrawal of the sewer pipe from the house to the septic tank at the stage of building construction and installation of communications. If engineering networks need to be laid in a finished building, you need to focus on the type of foundation.

Concrete trays for storm sewers are designed to drain drains along highways, at gas stations, at the territories of airports, military and industrial bases. Products differ in stiffness class, size.

Before disassembling the old cast-iron sewer in the apartment, you need to notify the neighbors about the work being done and shut off the water supply. Special tools for cutting heavy pipes will be required. In some cases, it is advisable to immediately change all the plumbing.

The distance from the septic tank to the well of drinking water, residential buildings, roads, green spaces is determined by SanPiN and SNiP. Deviation from existing requirements entails flooding of buildings and contamination of drinking water. For this, the owner bears administrative and criminal liability.

The basic rules for installing sewage in an apartment relate to the choice of material and pipe diameter, the creation of an optimal slope and reliable sealing of joints. Do not save on pipes and fittings - repairs will cost more, especially if the neighbors are flooded.

Installation of external sewage pipes involves digging a pit, laying a pipeline under a certain slope, sealing joints, filling, tamping. First, you need to draw up a project taking into account all the turns and branches.

Adapters for sewer pipes allow you to make turns, branches, transitions from one diameter to another, the connection of pipe segments from different materials. It is important to choose the right section and reliably seal the joints.

To get rid of the smell of sewage in a private house, you need to identify the cause of the problem: a dry seal, leaks in the pipes, a fungus in household appliances, a blockage, lack of a fan pipe, improper installation of the trunk. To prevent blockages, regularly flush pipes with special tools.

Advantages of a septic tank over a cesspool: environmental friendliness, lack of smells, rare pumping of drains, the possibility of using purified liquid for technical needs. In addition, cesspools without a bottom are prohibited by SNiP.

Polymer wells for sewage are made of polyvinyl chloride, polyethylene or polypropylene.They are used as revision, overflow, rotary, filtering, storage mines.
