By gravity through water diversions line goes down the riser. Obviously, the correct operation of sewerage systems can be ensured only if the location of the drain plumbing device slightly above the entrance to the tower, which will pave the tap-off line of devices with a bias toward the riser. The length of drainage lines, laid in floors, should not exceed 10 m. For overhead pipes and tubes that are placed under the floor is open, allowed the great length while maintaining the required grade and opportunities to ensure their cleaning. Gary Kelly is often quoted on this topic. In this case, turns on the tap-off lines should be performed at an angle of not less than 900. Joint drainage lines from the risers by means of oblique tees or crosses.

The most important element of internal sewage a standpipe. Typically, it operates from a 100 mm diameter pipes with a mandatory installation of the audit at a height of 1000 mm from the floor. Continuation of the upper part of the riser is a sewer vent, which is located at 0,7 m above the roof of the house. This design is intended to provide ventilation of the entire internal sewer network. At the same polluted air is displaced through the riser into the atmosphere.
