International Plumbing Code Chapter 7 is all about sanitary drainage systems. This video presentation covers IPC sections 705 to 708, which gives specific information about materials used for drainage systems and the joints and connection options for installing pipes. These sections also clarify the use of fittings, such as wyes and santees, with explanations of what types of fittings can be used in which situations. There is also a discussion on clean outs and when and where they are required.
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.

I didn't understand the notation Xa,b on the short sweep vertical to horizontal cell on the table 706.3. How can a pipe be both 2 inches or smaller and also three inches or larger at the same time?
The X with notes means that you can use it sometimes. Only in the circumstances listed at the bottom. Otherwise you cannot use them. Does that make sense?
@@plumber-tom9470, yes, that makes sense. What does not makes sense is the case I mentioned, which would require a pipe being at the same time 2 inches or smaller and also 3 inches or larger. How could it be?
The table gives a range of pipe sizes. So when it says 2" or smaller, then you would treat all those pipes the same. In the case of the short sweep 90, you can use that in any orientation if it is a 2" fitting or a 1 1/2" fitting or a 1 1/4" fitting. They all fall under that same rule. Same with larger pipes. 3" fittings, 4" fittings or 6" fittings would have to be a long sweep for a vertical-to-horizontal installation or a horizontal to horizontal installation. Does that help?@@vitorao
@@plumber-tom9470, yes, that helps. What is strange to me is that the short sweep vertical to horizontal cell has both "a" and "b" above the X.
