Description
The article describes methods of implementation of double stacks, which are a combination of sewage and ventilation bypass stacks.
Location in the program
The type of the stack is indicated in the Data table.
All necessary points should be specified.
Example of use
The program provides several schemes to perform such types of stacks. Schemes A-D are applicable to buildings from 3 to 5 floors (less or equal to 12m in height). Schema E - for the buildings with more than 5 floors (more than 12m in height)
- Schema A:
- Direct parallel ventilation: vent 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.
2. Schema A.
- Schema B:
- Indirect parallel ventilation: vent stack is connected to the branches on each floor;
- Air admittance valve is used like an Element on top of stack for both stacks (Sanitary drainage and Ventilation conduit).
3. Schema B.
- Schema С:
- Direct parallel ventilation: vent 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 are be made on each floor;
- connection to the vent stack from each sanitary appliance on the first floor and from each sewage branch on the floors above.
4. Schema C.
