Herein, what does the thermal relief valve do on a pressure washer?
The thermal relief valve keeps pressure cleaner pumps operating in a safe range to prevent overheating (caused by recirculating water). At water temperatures above 145º F, packing seals may fail. The pump then overheats. When the system is in bypass mode, the thermal relief valve opens to release hot water.
how do I stop my pressure washer from overheating? The water in the washer gets trapped and fresh cool water cannot enter. To release this water pull the trigger after about every minute. Do not keep your washer running if you are not going to use it for a while, simply turn it off. Overheating can cause permanent damage to your pump.
