The TripleSafe Sump Pump system provides 24/7 protection we three different pumps. A 1/3 hp pump handles the bulk of the work. The second pump is 1/2 hp and kicks in if the other pump fails or can't keep up. Finally, a battery backup pumping system kicks on in the event of a power outage to keep you safe and dry when the power is out. A SaniDry XP dehumidifier also helps remove water vapor from the air and directs it to the sump pump system for removal.
