As a followup to my post below, I have a shower floor drain that has a vent running vertically (up into the attic) in an adjacent wall. On the opposite side of that wall, I have a lavatory that is currently draining via thin walled pipe to the trap of another lav in a double lav configuration. I am wondering if it would be possible to have the lav drain directly into this nearby vent line (wet venting?). The shower drain is 2" and the vent is 1 1/2". The lav is less than two feet from the vent line.
