In this one I am questioning the appropriateness of the venting. The W.C. is at the top end of the drain, and the shower comes in and has a 2" vent line popping out of it using a combo wye and tee rolled 45. The vent thus vents the shower drain and the downhill W.C.
Look OK? Might I have used a sanitary tee for the vent instead?
