Sanitary Stack Sizing

When you define your sanitary run as a stack spanning 3 stories or less, or more than 3 stories, the plumbing
module performs the sizing calculations using the information on the Stacks tab in the sanitary plumbing
line sizing table (pipe sizing table), whose definitions can be found in Style Manager.

Sizing Sanitary Plumbing Lines

Sanitary plumbing line sizing is typically required for sanitary black water system types. When you create
sanitary system types for gray water, you need to define the system type as Waste in order for the sizing to
work.
If you are working on a sanitary system in a building that contains multiple floors, see
