I have a bathroom on the first floor of my house that was added in by the last owner. In the store room next to the bathroom is a pipe that goes down into a rubber disk that is about 2'-3' across. There is a power cord going down into it also. Is this my sump pump? The problem I'm having is when I take a shower there is water on top of this rubber disk that is about 1/2" deep that causes the room to smell pretty awful. I've noticed that when the toilet backs up there is also a layer of water on top. The storeroom is starting to smell pretty bad. Any recommendations?

Thanks,

Dan
