Code with flooring over sump pit
I am finishing our half basement and have a sump pit (no pump) in one corner of the concrete floor. I have lived in the house for 3 years (plus or minus a few deployments) and have never noticed any moisture down in it when I have bothered to remove the cover and look, though that has only been maybe half a dozen times. I am in Colorado, which is a very dry state.
Does anyone know if I can (by code) floor over the sump pit?
I assume that if I am allowed to, then that kinda answers if it would be a horrible idea to do it.
If I can't just floor over it (with Delta-FL and Plywood subfloor), then what kind of access am I required to have to get to it? Would I need to frame out that 10 sf of corner, leaving it as a utility closet with its own access needs?
I thought this would be a pretty easy google search, but I have not found anything approaching an answer. I COULD of course call and ask an inspector, but I'd rather be somewhat informed before that discussion.
