Water Pressure Unloaders, Valves, Regulators & Gauges

Pressure washer unloaders are critical in allowing your machine to go into bypass mode when the trigger isn't being pressed, thereby preventing an unwanted pressure buildup within the system. Our selection includes a wide assortment of power washer valve replacements to exactly match your machines max psi and GPM output and repair kits to fix broken unloaders. Find electric pressure washer unloader valves and pressure washer unloader valve kits here at affordable prices.

You'll also find pressure washer psi gauges in this section for accurately measuring water pressure. Our power washer pressure gauges come in 3000 psi and 5000 psi max options in stainless steel and bottom mount. Please note that the most accurate part of a pressure washer gauge is the middle third so if you are operating at a pressure range of 1500 psi you will need a 3000 psi gauge.

To protect your equipment from damaging heat buildup when it's in bypass mode, a thermal relief valve is called for. You'll find a selection here in 1/4-, 3/8- and 1/2-MPT. Also find jetter valves, pressure relief control valves, water pressure gauges and an assortment of chemical/detergent pickup lines and quick-coupled chemical injector lines.
