Hello,
Just wanted to start out by saying I sincerely appreciate all of the advice on this forum, and was wondering if anyone might offer advice with my particular situation.
I am planning to convert the current setup with the photo attached to accommodate a 72" double vanity, with the supply lines and drains coming from the wall.
My original plan was to have a conversion similar to the second attached photo I found on this forum. This has a similar orientation of the drains to the stack. This would require moving the current 1.5" pipe lower and converting it to a 2" pipe after the double santee, with a 1.5" vent going back to the 3" stack, as seen in the second photo.
I had a plumber come by who felt that this additional venting was unnecessary, and that an AAV at the further trap would suffice. Therefore, we could just lengthen the current 1.5" trap arm and put in two drains with the AAV. This would also avoid drilling additional holes in the studs, which they were worried about weakening support. This is a second floor non-exterior wall.
What does the group think? Thanks in advance.
