We upgraded this customer original sump pump to our SuperSump Pump. The SuperSump Pump is equipped with a 1/3HP zoeller cast iron pump with a mechanical float switch that pumps 2,650 gallons/hour. The SuperSump also includes a WaterWatch Alarm System that will sound off when water rises above the point where the pump should turn on and an Airtight Lid which keeps the liner neat and clean because nothing can fall in it.
