does this look ok?
the kitchen sink is under a window on a load bearing wall so I can really only go down to the crawlspace with the pipes. fortunately, the main drain line is located close to the ground level in the crawlspace so i have about 3' to play with between the floor and the drain. my concept is to run the sink drain down far enough to bring a drain up from the horizontal run and then send it horizontally over to a shared 2" vent in the laundry room wall. the laundry room and kitchen are both clean slates right now but ultimately i need the 3 drains in the locations shown. there is an old vent pipe in the room about 5' from where i have my roof vent shown. i'd prefer to tie my new vent to that old vent in the attic and just have 1 roof vent.
my main concern is with the kitchen sink vent, I suppose if the drain clogged after the vent, i could end up sending water up the drain pipe until it would end up going down the washer drain line instead.
