  • Dig a hole under the foundation and measure the width from the top to the bottom edge. The optimal value should be at least 100 cm, only in this case you can not worry about the freezing of the collector pipe;
  • On the street side dig a trench to the drain hole. The depth of the trench outside should be greater than the inside and should be at a slight angle to facilitate waste flow.

You have to lay the sewer pipes both inside the house and outside.

  1. At the bottom of the trenches, it is necessary to make a sand pad with a thickness of 20 cm. This will reduce the pressure on the polypropylene pipes. That is, due to the sand, the buried soil will not put much pressure on the structure;
  2. High-quality installation is impossible without proper sealing and pipe joints. To do this, during installation, insert tees into the pipes, which will help you to eliminate blockages during operation. You shouldn’t save at this stage - it all pays off very quickly;
  3. Tees are installed in 4-meter increments, and the part that comes to the surface is plugged with a plug.

A revision (tee) is installed on the riser at the level of 1 meter from the floor, from which the exhaust pipe is drawn to a height of 70 cm from the roof surface.

Such a complex installation system will help you avoid unpleasant smells in the house that accompany the installation of the sewer system. If ventilation is performed according to all requirements on the riser, then foreign smells will not penetrate the room and cause discomfort.

By all means consider thermal insulation of the riser located in a cold room.

Outlets with a diameter smaller than the diameter of the pipe on the riser are used to dock the riser with the external sewer system. According to professionals, the release should be mounted in the direction of the sewage at a right angle and connected to the riser with two taps with angles of 135 degrees. If necessary, an additional riser will require the use of an oblique tee and an additional tap. If there is one riser or collector pipe, labor costs will be much less.

External sewage is made of polypropylene pipes Ø150 mm.
