Hi all,
I'm replacing my shower/tub combo with separates and had a question on drainage. As you can see in image, original combo had a 1 1/2" pipe tying into the vent and drain line. I'm wondering for plumbing shower and bath separates:
1. Can I drain shower and tub down same trap arm (with both having separate p traps to tie into it)? Shower drain would reduce from 2" to 1 1/2" after ~4'.
2. Or can I have separate trap arms join right at the 1 1/2" opening shown in the photo?
Note: Shower is further and would slope 1/4" per 12".
