Through an annual maintenance visit on this Middletown homeowner's SuperSump Sump Pump System, Quality 1st's Service Technician Willie removed the airtight lid to access the cast-iron 1/3 hp Zoeller for cleaning and changing check valves. The Battery Backup pump was also cleaned and checked, enabling it to perform if the primary pump fails or if there is a power outage. The service technician also checked the float switch and replaced batteries on the WaterWatch alarm. The sump pump liner was cleaned and sanitized before the pump was reassembled. Through annual maintenance, the homeowner can have peace of mind in the reliability of their sump pump system to keep their basement dry!
