My kitchen sink drain became blocked and, while unblocking it with a plunger and lots of water, I saw the dirty water leak from behind drywall about 6 feet away from sink. I had previously noticed a smell from the same area and dampness on the drywall.
So I cut open the drywall and find an open pipe coming up from the floor, and the dirty water was coming out of that pipe. see picture attached.
I think this is wrong, probably against code, and I think I should put a screw on cap to close this pipe - but I'm guessing.
Please will someone give me their thoughts on this. Why is it like this, what's the purpose?
