International Plumbing Code Chapter 9 is all about sanitary drainage systems. This video presentation covers IPC sections 913 to 917. This video presentation contains explanations about venting drainage pipe using a variety of methods including the waste stack vent, circuit vent, combination drain and vent, island fixture vent, and the single stack vent systems.

This video is based on the 2021 International Plumbing Code, so chapter 9 might look a little different than previous or later versions of the code. Generally, the code requirements do not change much from one edition to the next.
