A TripleSafe sump pump system consists of 3 pumps to make sure that your home is protected at all times. A 1/3 hp pump handles the brunt of the work while a 1/2 hp pump is installed slightly higher to help remove water in the event that the first pump fails or can't keep up. A third pump runs on a battery backup and will take over if the power goes out. Your basement not only stays dry; it stays dry all the time.
