Most Frequent Causes for Pressure washer leaking water

Cause 1Pump Assembly

You may need to rebuild or replace the pump assembly. If the pump is more than a few years old, and you use the pressure washer fairly often, replace the pump assembly. If the pump is relatively new, and you don’t use the pressure washer often, either rebuild the pump assembly or replace the pump seals.

Cause 2Thermal Release Valve

The leak could be due to the normal operation of the thermal release valve. The thermal release valve allows hot water to exit the pressure washer if the water temperature becomes excessively high. If the pressure washer is left running while it is not spraying water, the water in the pump will begin to heat up. When the water temperature rises above the acceptable limit, the thermal release valve opens to allow the hot water to exit the pressure washer.
