Pentair Water Pressure Switch Boot | ThermalFlo HP Titanium & UltraTemp ETi | 473606Z

Description

The Pentair Water Pressure Switch Boot (473606Z) is the OEM replacement boot for the water pressure switch on ThermalFlo HP Titanium heat pumps and UltraTemp ETi heaters.

IMPORTANT: LICENSED PROFESSIONAL INSTALLATION REQUIRED
Gas and electrical heater components must be serviced by a licensed pool professional or qualified HVAC technician. Do not attempt to service gas or high-voltage components without proper certification.

This boot seals and protects the water pressure switch on the unit’s plumbing connection, keeping water out of the switch housing so the switch can reliably monitor water flow before the heat pump or heater’s electrical components are allowed to energize. A cracked, hardened, or ill-fitting boot is a common cause of water intrusion and pressure switch faults.

Poolaroo Pro Tip

A brittle or cracked pressure switch boot is a common source of water intrusion faults on ThermalFlo HP Titanium and UltraTemp ETi units. If you’re already replacing the water pressure switch, inspect and replace this boot at the same time to avoid a repeat service call.
