We are excited to announce: the IPC practice tests & video courses

Also in the works are:

-DWV venting course

International Plumbing Code Chapter 9 is all about sanitary drainage systems. This video presentation covers IPC section 906 which is all about DWV vent sizing. This video includes explanations about the requirements for vent sizes as well as demonstrations on how to size drainage vent pipe.

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.

Just found your channel. I’m currently an apprentice. Thank you for your content. Plumbing code puts me to sleep but you make it interesting.

May I ask why in 9:41 the developed length does not start from the bottom level where the vent connects to the drain as the "farthest point"? To me that seems to include the entire length of the vent.

Seems to me, in your example, 140 DFU would need a 4" vent, before you get to the stack vent. I'm totally confused.

Could you do a video on fuel gas pipe sizing?
