Product details
Description
Protect your high-pressure washer pump from costly heat damage with the Sellerocity 135F Thermal Relief Safety Valve. When a pressure washer idles with the spray gun trigger closed, trapped water rapidly heats up and threatens to melt or crack internal pump seals and ceramic plungers.
This thermal dump valve automatically opens when internal water temperatures reach 135 degrees Fahrenheit, safely venting the overheated water and allowing cooler water to enter. Crafted with a heavy-duty brass body and a integrated 1/4 inch plastic barb, it allows you to attach a return hose to safely redirect discharged water back to your supply tank or ground.
Featuring standard 1/2 inch NPT threads that measure approximately 0.840 inches, this essential replacement accessory extends the lifespan of your equipment and maintains peak cleaning performance during intensive tasks.
How to use
- Ensure the pressure washer is turned off and completely depressurized before installation.
- Remove the old thermal relief valve from the pump manifold.
- Apply appropriate thread sealant or tape to the 1/2 inch NPT threads of the Sellerocity valve and screw it securely into the pump manifold port.
- Attach a compatible discharge hose to the 1/4 inch barb if you wish to redirect expelled water.
- Test the pressure washer to ensure there are no leaks.

FAQs
What is a thermal relief valve pressure washer?
A thermal relief valve is a safety device installed on high-pressure washer pumps to prevent overheating. When the machine runs while idle and the trigger is not pulled, trapped water heats up. The valve opens automatically to dump the hot water and protect internal components from failing.
Why is my pressure washer spraying water from the relief valve?
If water is spraying from the valve, it typically means the internal water temperature has exceeded 135 degrees Fahrenheit due to the pump running continuously while idle. It can also indicate that the valve spring has worn out and needs to be replaced with a new unit.
My pressure washer thermal relief valve is stuck. What can I do to fix it?
A stuck or failing thermal relief valve cannot usually be repaired and should be replaced entirely to prevent pump burnout. Ensure you match the thread size and temperature rating, such as this 1/2 inch NPT 135F model, before installing a replacement.
