Hi, I live in New Hampshire on a lake and am only 6" above water level. When it rains a lot in a good storm my cellar gets flooded. I am looking for a good way to pump the water back into the lake. WE have about a 50' run to the lake. Any help would be grateful.I have a patio under my deck and that is where the water comes in. We do have a pump in the cellar but, that only takes care of the water after it comes in the house.
