Im not sure if this is the right forum, but I am guessing it is. I dont do a ton with plumbing, but recently the shower in our basement was giving off a peculiar smell. So I got a little closer and it turns out its coming from the drain. We dont ever use this shower and the smell is not coming from any other drains. I was thinking perhaps some water had evaporated from the trap and letting sewer gas through, but even after running the shower, the smell seems to come back pretty fast. I though maybe a vent pipe was clogged to, but its only coming out this one location. Any ideas?
