Quality 1st Service Technician Jerry provided this homeowner with top notch annual maintenance on the TripleSafe Sump Pump system. As the liner can accumulate dirt and sediment as ground water passes through the system, Jerry cleaned the primary 1/2 hp cast-iron Zoeller pump as well as the secondary 1/2 hp pump and the UltraSump Battery Backup Sump Pump. Check valves were replaced, weep holes cleared, pump stands and the pump liner were cleaned and sanitized, and the WaterWatch Alarm batteries were replaced. All parts were reassembled, replaced in the liner, and closed with the watertight lid to keep debris from entering. The system could continue pumping efficiently as an effective wet basement solution!
