Pressure washer unloader valve kits from Hot Power Washers can increase the useful life of your pressure washer. A power washer unloader is a simple spring-valve arrangement. The channel drilled through the body of the unloader allows water to move to the back of the valve ball. When there is excessive pressure against the valve, spring tension overrides, and the water is diverted through the bypass. At Hot power washers, we have pump unloader kits to allow you to stop water flow when the machine is not working.
