To keep a SuperSump Sump Pump System operating at its best as a reliable wet basement solution, Quality 1st recommends annual maintenance. The airtight lid is removed to access the cast iron 1/3 hp Zoeller for cleaning, changing check valves, and checking the float switch. The WaterWatch alarm batteries are replaced and the sump pump liner is cleaned and sanitized. Annual maintenance performed in Trenton, the operation and life of this homeowner's SuperSump system was enhanced through the annual maintenance performed by Jerry, one of Quality 1st's Service Technicians.
