Quality 1st Service technician Frank provided this homeowner with top notch annual maintenance on the TripleSafe Sump Pump wet basement solution. As the liner can accumulate dirt and sediment as ground water passes through the system, Frank cleaned the primary 1/3 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 were cleaned and liner was sanitized. All parts were reassembled, replaced in the liner, and closed with the watertight lid to keep debris from entering. The system could continue pumping up to 2,220 gallons of water per hour at an 8-foot head effectively and efficiently!
