During an annual maintenance visit in Swedesboro, Quality 1st Service Technician Jerry removed the airtight lid to access the 1/3 hp Zoeller pump for cleaning. He also changed the check valves. The WaterWatch Alarm batteries were replaced to be ready to alert the homeowner if the pump fails. The liner was cleaned and sanitized and the system was flood tested to ensure the system keep operating effectively and efficiently to keep the basement free of water intrusion!
