7101359 Thermal Relief Valve Replacement For Pressure Washer Pumps - 1/4 Inch NPT Brass Valve

Did your pressure washer pump overheat and now it's acting up or leaking? This little brass valve is a super common replacement part. It's the thermal relief valve, part number 7101359. Its job is super important: if the pump water gets too hot (like when you leave the machine on but the trigger off), this valve opens up to let the hot water out and allow cooler water to flow in, protecting the internal seals and parts from damage. It's made of solid brass for durability and has 1/4-inch NPT threads. The outer diameter of the male thread is 1/2 inch, and the whole thing is about 1.7 inches long. It's rated for pumps with a max inlet pressure of 200 PSI. If your pump has ever overheated, replacing this valve is one of the first things to try. It's a straightforward fix that can get your power washer back in action for all those cleaning projects. Just make sure your pump's port is also 1/4-inch NPT!
