Sewage installations - Bypass ventilation

Description

The article describes methods of implementation of double stacks, which are a combination of sewage and ventilation bypass stacks.

The type of the stack is indicated in the Data table.

Following points should be specified:

Automatic creation of parallel ventilation;
Element on top of the vent stack;
Elevation of upper point of connection of ventilation stack to drainage stack;
Elevation of lower conn. of vent stack to drain stack;
Generate intermediate ventilation connections.

The program provides several ways to perform such types of stacks.

Schema A:
- Parallel ventilation stack is connected to the sewage stack at the bottom near the stack foot and at the top to the vent cowl.
- Generate intermediate ventilation connections can be made or not depending on the project features. In the presented example, this type of connection is made.
