Installation rules for internal sewerage
Sewer installation is always carried out in parallel with the installation of plumbing and heating. The design of these systems is also carried out simultaneously, considering interdependent factors. For installation, the intermediate stage is especially important - when the engineers transfer the drawings to the installation team.
Technical documentation must be prepared – it indicates all horizontal and vertical references, development drawings with references to outlets, water outlets, sewer outlets.
Alter Air has its installers. Thus, trusting us not only with the installation, but also with the project, you entrust the work to one company, which is responsible for the entire process. There will be no communication problems in the team that deals with your project.
The main principle that should be observed when performing installation is the mandatory slope of the pipes. It should be from 1 to 2 centimeters, depending on whether clean water or waste with feces flows through the pipeline. The slope helps to avoid blockages – without it, sewage disposals will not be able to move through the pipes into the drain. For internal sewerage, pipes with a diameter of 20 to 100 mm are used. For example, for pipes in showers, bathtubs or sinks, the pipe diameter is 50 mm, for toilets – 110 mm. Pipes are laid in the walls, not in the floor – this is the only way to achieve the desired angle.
Fan pipes (pipe section that connects the sewer system to the atmosphere) are installed only vertically and go to the roof. The purpose of this type of pipe is to remove odors and air from the sewerage system. For connection, the types “female” or “male” are used, depending on the parts used. When installing an internal sewerage system, it is important to check and eliminate blockages – this is done thanks to pipe clean out.
