I've been renovating the kitchen thinking of adding in a dishwasher and when I tore open the wall I found what I believe is a capped off vent line. The PVC has a cap on it and the run goes, from what I can tell, straight up.
Checking in the basement and there is a pretty obvious cut/patch that looks like it used to feed that line into the main sewer line. I believe it was done to move the sink at some point and as far as I can tell the sink line runs directly into the main now.
So I am thinking two things, 1) do I need to do anything about that pipe and 2) if I do I'm guessing it's going to have water in it (from rain going through the vent through the roof?) and finally there isn't much room to fix it in crawl, I'd probably have to run it through the wall/cut holes in the studs to bring it back to the sink trap line.

That's what I was thinking, unfortunately it's really tight in the crawl to get that Y in there. Secondly when I cut that pipe I'm guessing it's going to be full or at least have some water in it.
I know that fixing it is the right plan, we've lived with it like that for a while though, negatives of leaving it?

place a bucket
drill a 1/8" hole sideways at the base to drain any water
chew a piece of bubble gum just in case

assuming there is a trap under that sink, the only way it can run down thru the floor would be to make it a full 'S' trap. so even if you vent it below the floor it still won't be right.

Yes, sorry in my very very crude drawing there is a full s-trap under the sink. Hence we haven't had any sewer gas issues or anything else backing up or draining slowing. Not sure if it helps that we have a sink grinder that feeds the sink line.
I was more worried about the capped pipe in the wall, not necessarily the sink itself.

I know we're several states away, but I like your attitude. Sounds like something my father would have said. Thanks for the advice.
