Replaces the water pressure safety switch on Pentair MasterTemp and Sta-Rite Max-E-Therm 200-400 heaters, including the ETi 400 (42001-0060S). It verifies sufficient water flow so the heater only fires when circulation is present, preventing dry-firing. Genuine OEM part; installs on the heater manifold and is supplied without adapters.
