Confirm the full equipment model against its parts diagram before installation. Isolate electrical power where applicable and close connected seacocks before opening the system. Follow the equipment service instructions and check for leaks after reassembly.
Parts Desk Insight
A leaking diaphragm and dirty check valves cause different symptoms. The service manual calls for diaphragm replacement when the pump leaks, while reduced flow also calls for checking valve debris.
