Fitment and Installation
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
Pressure rating alone does not establish fit. Match the pump’s full model number and switch assembly before ordering; a different-pressure switch changes how the water system cycles.
