We recently bought a home close to a lake. The house has 2 sump pits and the previous owners had raised the pumps due to a high water table. I don't like the smell of stagnant water so I lowers the pumps back down. They are sort of right... we are pumping a lot of water but it's from an underground spring! The water is rushing in to the front pump! The first couple of days after lowering the pumps there was a horrid smell which I figured was the drain tiles airing out. Bow, 2 months later, I am getting a bad sewage smell again. We are on a septic system and the water is rushing from the front of the house to the back of the house so I know it's not coming from my septic system. I have 2 questions. 1. what else could this smell be from? And 2. Is there anything I can do to decrease the amount of water coming into my pits?
