Protect Your Pump from Heat!

“Leaving a pressure washer running with the spray gun off used to overheat internal seals and destroy pump components in minutes. This Pressure Washer 1/2" Pump Thermal Protector senses dangerous temperature spikes and releases hot fluid so cool water can protect the system instantly.” — Brian K.

Why Get Our Pressure Washer 1/2" Pump Thermal Protector? 

✅ Reduce Heat Buildup: Help protect your pressure washer pump from damaging heat buildup while it is in bypass mode. The thermal relief valve senses rising temperature and opens to release a small amount of heated water.

✅ Let Cooler Water In: Releasing heated water allows cooler water to enter the system. This helps cool the pump during bypass operation.

✅ Automatic Valve Closure: When the spray gun is discharged, cooler water causes the valve to close immediately. The valve responds to changing water temperature as you resume spraying.
