Sump pumps can become dirty and laden with sand or silt as ground water passes through to be pumped out of the living area. It is important to have annual maintence performed on basement waterproofing systems to keep them operating effectively and efficiently. Service Technician Nelson visited Martinsville, NJ to check this customer's SuperSump Sump Pump System. After removing the airtight lid, the pump system was disassembled for checking and cleaning. The pumps and their components were cleaned: Nelson cleaned the impellers, the breathing holes, the pump stands, the liner, and the lids. He replaced the check valves and replaced batteries in the WaterWatch Alarm System and reassembled the system. All clean, Nelson tested the system and left the homeowner with a sump pump system operating at peak performance, ready to pump out up to 2,220 gallons of water per hour with the primary pump!
