Proper drain size

Hi Gang,

Just wanted to verify a couple things:

1. An ADA shower drain (or really any shower drain) needs to be 2" by code for most if not all areas, yes? (State of Maryland is my main concern).

2. Sanitary T is only meant to be installed vertically, not horizontally. Instead of a sanitary T, use a Y for horizontal runs, correct?

Thanks! Greg

2" is correct on the drain...not sure on the other issues.

you are right.

See this https://terrylove.com/forums/showthread.php?t=14696 which has pictures too.

To connect two drain pipes in the horizontal plane, use a Wye.

Thanks!

Thanks for the replies. Greg
