Quality 1st Service Technician Cameron took special care in performing annual maintenance on the SuperSump Sump Pump System at this home in Parkville, MD. After removing the airtight lid, he removed and disassembled the pump system for cleaning and to check all components. He also changed the check valves, cleaned the sump stands and liner, and then reassembled the system for testing. All set, the SuperSump was ready to jump back into action with the capability of removing up to 2,220 gallons of water per hour on the main 1/3 hp pump!
