Our basement bed room closet has a pump in it and it has been out of commission for awhile. We bought a new pump and there is an odor in that room now and we can't seem to get it to go away. What can we do to help prevent this.

We have a bath in our basement and it had been down for a couple of years and now it is up an running. But we smell sewage in the closet where the sump pump is located. What can we do to get the odor gone?
