I thought I posted a thread about this, but I didn't find it. The vanity project is coming to an ignoble end when the granite guys show up on monday. The sink always had an s-trap because the wall behind the vanity isn't thick enough for a vent pipe. The compression fitting for the s trap is at the floor level, and it's right below the sink drain. I'm thinking about going from there up with a pipe, slanted over to the back corner of the vanity. Then put in a Studor air admittance valve.
I'm not sure we ever really had a venting problem, but this seems like it would be better than nothing. Any thoughts?
