About This Item
The Pentair Water Pressure Switch (473605Z) is the OEM replacement pressure switch for the ThermalFlo HP Titanium heat pump series.
⚠️ IMPORTANT: LICENSED PROFESSIONAL INSTALLATION REQUIRED
Heat pump components must be serviced by a licensed pool professional or qualified HVAC technician. Do not attempt to service high-voltage components without proper certification.
The water pressure switch monitors flow through the heat pump and signals the unit to operate only when adequate water circulation is present. When this switch fails, the heat pump may refuse to start, shut down unexpectedly, or fail to detect flow — preventing heating entirely. Replacing a faulty switch restores the heat pump's ability to confirm safe operating conditions before engaging the refrigeration cycle.
