Greetings, everyone.
I'd like to tap into an existing DWV system to add a clothes washer standpipe, but I'm not sure how best to do it. We use the California Plumbing Code here.
There is a bathroom on the other side of the wall, with two vents running in the common wall. Ideally, I could tap into the 2" WC vent and wet vent the WC with the standpipe's drain if that's allowable. Another option I see is to tap into the vent only for vent purposes and drain to a 2" cleanout below the floor. I hesitate to drain below the floor because it will require either more exposed DWV piping or obliterating an already heavily cut sole plate on the common wall.
Can I simply tap into the WC vent and wet vent that line?
I hope the photos are self explanatory.
Many thanks for your help.
