am new to this site. I have received signed contract for bank owned house. There are two sump pump. One in the pit in the basement ....the other one in the sand pit and is hanging over the sewer cap. This area is somewhat wet and the inspection guy smelled sewer. He flushed the bathroom couple of times to check the leak. But he cound not find any thing...he has some doubt and feels there may be a leak in the sewer pipe, but he is not sure of that. This doubt is due to:

Sump pump in the sand pit. Is this abnormal to have sump pump in sand pit?
wetness in the sand pit area

any help would be appreciated.
