Service Technician Nelson completed a full annual service on this Pennington homeowner's TripleSafe Sump Pump System. He removed the pumps and cleaned and inspected all components. He cleaned the impellers, the breathing holes, the pump stands, the liner, and the liner cover. He replaced the check valves and the 9-volt battery on the WaterWatch Alarm. The system was flood tested to ensure everything was working properly and left the customer with freedom from worry of groundwater intrusion into the basement!
