Terminology Riser
• Vertical water supply piping supplying more one floor or more
Stack• Vertical DWV piping (exceptions vertical fixtures and
vented stacks…ie stack vents, vent stacks)
Branch• Horizontal piping (water and DWV) for plumbing
other than a riser, main or stack
Main• Principal pipe supply for connecting branches
