I'm currently renovating a master bath and we are replacing a double vanity with the exact same setup. I took the drywall down to add some new electrical plugs and I came across this drain set up which although appears to have worked on the left, I don't think is up to code.
I don't see an issue with the right side as it is a sanitary tee to the drain which vents straight up. The left on the other hand connects to the drain/vent with a wye and 45 above the cleanout and below the sanitary tee for the right sink. Not a plumber by trade but this looks to me like an s-trap.
The pipe halfway up the wall on the left is the vent from the floor below tying back in.
Close up of the wye below the tee. Basically goes wye for cleanout, wye for left sink, sanitary tee for right sink all together in a row.
I am thinking that if I put a couple sanitary tee's in here and tie into the vent from below (it's at 42") then this would be the quick fix that would meet code without having to redo it all. Am I off base on this plan? Or do I need to do a wye-45 at the bottom up to a sanitary tee on the top tying back into the vent? Or is this just completely wrong.
