I bought this for my basement that was getting flooded by my old sump pump that could not keep up with the rain water overflow. This pump is very quiet. It is able to keep up with our rain storms. The float had be be removed and another one installed for about $40. Since I used an e-certificate it was a deal for me. The float on this model needs too much pressure before it will pump the water out. Overall I am very happy with this model.
