great. so new tee below the current tee, correct? so single vent with 2 tees, one for each lav. and AAV on both lavs between the trap and the vent tee? thanks a bunch.You can tee below, come out of the wall, and run to the other lav. I would then add a AAV to prevent the trap siphoning. I will be adding an AAV to a lav tomorrow. They did something similar, but in the wall, coming up with a 90 bend before hitting the p-trap. There is a godawful smell coming from that lav.
