This basement had no sump pump, so we needed to install one. Not wanting to ever experience a flooded basement, our customer had us install a TripleSafe Sump System with a battery back-up. As the name implies, the Triple Safe has three pumps. Pump 1 does the majority of the pumping. Pump 2 kicks in if Pump 1 is unable to keep up during a severe storm; and Pump 3 is the UltraSump Battery Back-up system. If you lose power, the UltraSump’s 120 amp power pack, when fully charged, can pump a total of 12,000 gallons of water, at 2,018 gallons per hour. Barring a severe storm that leaves you without power for more than a few days, the UltraSump should get you through until power is restored and the battery can begin to charge again.
