International Plumbing Code Chapter 7 is all about sanitary drainage systems. This video presentation covers IPC sections 709 to 710, which gives specific information about drainage pipe sizing. This includes an explanation of the tables used to size DWV pipe, as well as multiple examples of how to size drainage pipe.
This video is based on the 2021 International Plumbing Code, so chapter 7 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.

As a master plumber in Ohio & West Virginia, I am impressed by your presentations. Wish I had access to videos like these as a young plumber. You do an excellent job explaining in simple terms some very difficult code and meaning. Keep up the great work!

Thanks for the video, very informative. I am remodeling a bathroom changing a tub to a shower. Most of the drains for pans etc are 2”, but existing line is 1 1/2”. Since the rules on showerheads are 2 gpm, do I need to change it to 2”?

@plumber-tom9470 3 ай бұрын

No. 1 1/2” should be ok for a shower.

@@plumber-tom9470 thanks, I think some local codes require 2”, but I just went for plan review and mine doesn’t

So let’s say I have two bathroom units on a second story draining down to the first floor on a 3” pipe, then that 3” runs to the main sewage line under the slab. Can I tie 7 more DFUs into the 3”?

On the tables in chapter 7 you will find then number of drainage fixture units for pipe sizes. It sounds like you should be fine if you have two bathroom groups and the other 7 DFUs. A bathroom group is 5 DFUs. And a 3" horizontal branch can handle 20 DFU. So it sounds like you have 17 DFU total and you should be fine.
