Thermal Relief Valve 3/8in Pressure Washer

Quick Overview

  • Protects the pump from damaging heat build-up while it is in bypass mode by releasing the water outside the pressure washer
  • The thermal relief valve, sensing a rise in temperature, opens and discharges a small amount of heated fluid
  • This allows cooler water to enter the system and cool the pump.
  • When the trigger gun is operated again then the cooler water that enters the pressure washer will cause the valve to close immediately
