Bathroom remodel DWV Venting
OK, am in the process of beginning plumbing for a bathroom remodel. The bathroom is a 8x8 square. The toilet and shower are more or less next to each other. The plan is to drain the shower into the 3" toilet drain line using a short horizontal run and a reducing wye; I don't see any problem with that.
There is a stub wall between. the shower and toilet. Can the shower and toilet vents rise about 6" above the drain line, meet under the floor, and tee into a 2" vertical vent pipe that will run up the stub wall? Hope this question is clear... thanks for any/all advice.
