Hello fine folks. I'm hopeful that I've posted this in the right section as I'm looking for a little help with some plumbing changes I'd like to make in my laundry room and I live in BC Canada. I've read countless other threads but none seemed to be exactly the same as mine. Anyhoo... So currently I have a large concrete laundry sink that drains into a 2" drain stack. Straight above is the kitchen where the sink also drains into the same line so I guess the laundry sink is wet vented. We have a washing machine that drains into the concrete sink and has left the surface of the concrete all pitted and nasty. The diagram below shows the current set up:
So, what I'd like to do is add a branch with a stand pipe for the washing machine. I'd stack the washer and dryer and replace the sink with one mounted into a base cabinet. Because there is a window over the sink I want to run all the plumbing inside the cabinet so I'm not drilling any studs; this limits the height of my venting. I realize that the washer's drain will need it's own vent so, when I remodeled the upstairs I thought to tie in a 1 1/2" abs line in the wall near the ceiling and ran it straight down into the closet below. It's currently hidden in the closet with a cap on it ready to use. So I'm wondering if I can simply bring it down low enough to fit in the back of my proposed sink cabinet and tie it in at some point? I tried to draw it out below. Also wondering if it's okay to leave the sink wet vented as it is currently. For reference the drain from the sink will be about 3' from the stack and the standpipe would be about 7' from the stack. Any help much appreciated!
