I need help identifying this hole in my basement floor. It's next to the main stack, and kind of looks like an old cleanout. The stack has a new cleanout installed right above the photo - you can see the white PVC.
I've figured out that my basement odor is coming from this hole, but I'm not exactly sure what to do with it.
It had a cap on it, just loosely sitting on the hole and not sealed - I easily removed it by hand. Should I stick it back on there and permanently seal it with something? What should I use?
Why would it have been like this in the first place? Is it suggestive of some other issue?
The dampness on the floor is from when I spilled some water. I poured some in in case there was a dry trap causing the odor. This didn't solve the odor problem, perhaps because I didn't pour in enough water to fill the trap.
Thanks for any advice on what I should do here!
