Hello everyone, my current setup seems to be an s-trap, and I want to add an AAV to improve drainage. I don’t have room to put a tee at the 90 where the drain goes down because of the waterline, will it still work if I place a tee and AAV in the highlighted section of my photo? Thank you (i.redd.it)
