Venting Kitchen Sink Under Window in California
Hi all! I'm realatively new to plumbing, and having a little trouble with fixing the existing hack job that I just found when I removed my sink to insulate an exterior wall.
Here's what I'm working with. One king and two cripples notched down to only 20% left on the backside. 36" window above a 34" sink in a 36" cabinet.
Code seems to prevent mechanically reinforcing with steel plate or moving the vent T below the floor ("wet"). Found this explanation on another site, but can't get my head around it. Does anybody have a diagram that might help me visualize it?
Your other option is to stub out through the drywall in both stud cavities, then install cabinets, and drill and connect piping as needed in the back of cabinets. More than likely going to need piping graded at 1/4" per foot in cabinets. . . . .
Oregon plumbing code allows us to be as high as possible under structural conditions and then use drainage fittings if we are less than 6" above the flood level rim. Be sure there isn't a provision like this in CA code.
