Quality 1st Service Technician Justin performed annual maintenance on this homeowner's SuperSump Sump Pump System in Linden, NJ. The airtight lid was removed to access the cast iron 1/3 hp Zoeller pump. Justin cleaned all components, changed the check valves, and he checked the float switch. He replaced the batteries on the WaterWatch alarm. The sump pump liner was cleaned and sanitized. Then the pump system was reassembled and flood checked to ensure the system keep operating at peak performance, capable of pumping up to 2,220 gallons of water per hour!
