When building your own home, even taking into account all possible costs, situations often arise that force you to deviate from the conceived plan, as well as lead to additional costs. So the money has already ended, and communications have not yet been laid. The way out of this situation may be to bring the sewage system to the building on your own. Let's consider the peculiarities of pipe-laying with our own hands.
All work begins with the drafting of a sewerage system and the purchase of the necessary equipment, such as cast iron valves , pipes , fittings, etc. The project of an autonomous sewerage system should take into account the following features of the site: the depth of the groundwater; composition and structure of the soil; the level of soil freezing; expected mechanical stress on the drain.
In addition, the project marks the places of sewer drains, which are available not only in the house, but also in the yard. The location of the septic tank, the place of water intake, the line for laying the sewage system, the turns of the pipes, their joints, the location of the inspectors are indicated. At the same stage, the material of the pipes is selected, whether they require thermal insulation and a drainage device, and the required number of adapters is determined.
Ten factors affecting the performance of the sewerage system of a private house:
- The most optimal for an autonomous sewerage system are pipes with a diameter of 110 millimeters, while plumbing fixtures are connected to the system by pipes with a diameter of 50 millimeters.
- Elbows and adapters must have a horizontal angle of 45 degrees.
- Sewer pipes in the area from the drain to the septic tank should be laid at an angle of two centimeters for each running meter.
- If pipes are laid through a section, it is necessary to equip inspection (inspection) wells.
- It will be necessary to insulate the pipeline system if it passes through a zone of freezing soil.
- Silicone or other sealant is used to prevent leaks and seal joints.
- The starting point of any sewerage system is the place of discharge, and it ends with a drain (septic tank) or treatment equipment.
- Ventilation openings must be provided to remove accumulated gases in the system.
- The installation of cast iron pipes involves the use of specialized equipment and technology.
- Sewer pipes are laid only after the markings on the site have been made.
