What pitfalls await when planning your own sewer wiring

Today it is impossible to imagine a normal comfortable life without such things as plumbing and sewage. Residents of cities take these benefits of civilization for granted. But the owners of private houses have to equip their homes on their own, including planning the layout of sewers. What mistakes can be made in this case, and what pitfalls can an inexperienced developer come across, we will tell in this article.

One of the most common mistakes in planning and installing a sewer system is the lack of ventilation risers. This serious flaw can lead to a vacuum in the system. As a result, gurgling will occur, noise in the pipes, unpleasant odors will begin to spread throughout the house. The location of the riser is best planned on the roof. You cannot connect more than 5 sewer branches to one riser.

When developing a project for future sewage, it is necessary to take into account the noise level of wastewater in the pipes. If they will pass inside the walls, it is necessary to take care of sound insulation. For this purpose, you can use mineral wool or glass wool. Strobes with pipes are conveniently covered with sheets of drywall. It is also necessary to correctly calculate the depth of the pipes. Despite the fact that the sewage does not freeze, as it has a high temperature and is constantly moving, the pipes should lie at a depth of at least 80 cm.

In some cases, a wastewater return valve must be included in the plan. It is necessary in cases where there is a danger of "return" of sewage due to a sharp filling of the sewer well, for example, during a thunderstorm. Insufficient diameter and congestion of the sewer pipe may also be the cause of the "reverse draft" of sewage. In addition, the pipe may become clogged, which will also lead to a reverse outflow of sewage.

If it is planned to use a septic tank as a sewage collection tank, it is imperative to provide ventilation for the tank in terms of sewage. Otherwise, unpleasant odors will always "delight" not only the neighbors, but also the owners of the house. In addition, a plug of toxic gases formed in the septic tank will not only be a source of disgusting odor, but also an obstacle to the flow of sewage into the septic tank.

Another “pitfall” in planning sewer wiring is the incorrect calculation of pipe lengths. Sewer pipe passing under the floor must be continuous, without joints and connections. If a breakthrough occurs at the junction (which is very likely), and there is a garage or basement under the pipes, the “fun” in the form of a complete disassembly of the floor covering and elimination of the consequences is guaranteed to the owners.

If you do not have the necessary experience, it is best to order a sewer project for a private house from specialists who will take into account all the nuances.
