My 30-year-old Laundry room (LR) has a WM drain with no trap or vent. So, I am remodeling trying to place a new drain, trap and vent.
I just started and found the wall cavity is on 12 inch centers. Hardly room to place a 2 inch trap. Its an external wall so I am not inclined to file permit to modify studs. Or is this my only option?
I am permitted in Redmond, WA to add a AAV and new drain. How? IF I am able to get a line in, no trap will fit.
Am I forced to put a trap outside the wall?
Is putting a trap on a horz section below the floor in the crawl space with AAV vent a bad idea?
