I set the ejector to drain the sump before filling to the level of the drain pipe, flushed the floor drain with lots of fresh water and now I have no more odor. My floor drain was not covered with carpet. I hope this helps you.
How did you figure out this was the problem though? We dont have a septic so is the pump you're talking about seperate from that? We did have water on the walls in part of the basement the day we signed the papers and we do know that we have to put in interior tiling and a sump pump but they only take out the very lower portion of the walls so I doubt we'd get lucjy enough to find the problem when they do that....
