Tub draining into 2" trap, 1 ft arm then wye on its back for vertical vent tie-in, then another 5 ft before the first horizontal long sweep 90 turn. Where does the "cleanout at the upper end of the draining pipe" go? Do I put a wye on its side right after the trap arm, or do I use a cleanout fitting so it can be cleaned towards the trap too?
EDIT --- rather than open a thread for every question, one more thing I'm trying to figure out:
I need to run in the opposite direction of the 3" drain line in order to vent my tub and shower. what's the right order of fittings and cleanouts to make the 180 deg turn and connection? I was thinking trap -> cleanout -> wye for vertical vent -> long 90 -> wye on its side with cleanout at the 135 turn mark -> 45 (then we're in same direction as 3") -> and then 45 + wye "vertical" into the 3" --- does that sound right or is there an easier solution?
