WOW Denine! I would think 100 gallons from a sump pump for only 2+ inches of water.... I would be calling your contractor! Your house isn't that old, and it's not like you live on a farm or that rural of an area for you to have this many problems with your house. You have had your pipes freeze, Jerry had to dig out around the one side of your house with the snow, your every year flooded backyard, and now the sump pump and 100 gallons.... I would be suing the builders.... Do they have lemon laws for houses?
