Is there some clever routing of pipes that would allow me to install a waste standpipe in this crowded wall?

Author: md9918 (MD)

I am replacing the galv vent manifold and swapping out the ferncos with mission couplings and would like to add a laundry standpipe if possible. Laundry box is installed as shown, but can be moved between those two studs. I just don't think there's room between the studs with all the other plumbing, but am curious if there's a pipe layout I'm not thinking of.

Room where the photo is taken is now a finished bath-- toilet flange and shower are labeled.

My thought is to run the lav sink trap arm to the toilet vent and wet vent the toilet. Offset the "lav sink drain" pipe towards laundry room, install sanitary tee for standpipe trap and extend vent for standpipe(out top of sanitary tee) up above the drain box and reconnect to the existing vent pipe. Replace the vent sanitary tee, that's above the existing lav sink sanitary tee, with a 90*.

Author: packy (MA) they make small washing machine boxes. one is for drain only and the other has the shut offs. they can be installed side by side or separately. maybe this will help. [www.ebay.com]
