Pressure Washer FAQ
PSI refers to water pressure, measured in pounds per square inch. Pressure determines how much force is applied to break down stubborn dirt and grime.
GPM is the water flow delivered to the spray gun, measured in gallons per minute. Flow determines how much water runs through the system and provides the muscle to break down dirt faster and remove it from the area.
Pressure washers are rated by PSI (pounds per square inch) and GPM (gallons per minute). The higher these numbers are, the faster and more effective the cleaning.
Yes, but different projects require different combinations of pressure and flow for the best results. Use the nozzles to control the pressure and flow for each project.
No, both the water pressure and the water flow are equally important. the pressure breaks down the dirt and the flow removes it from the area.
Yes, the detergent injection system enables you to achieve better cleaning results by using cleaning detergents to help break down dirt and grime. (Do not use chlorine bleach; voids product warranty).
No, only detergents that are specifically approved for pressure washer use are recommended. Using detergents that are not approved for pressure washer use voids the warranty, may damage the pressure washer, and may not be environmentally sound. (Do not use chlorine bleach; voids product warranty).
A bypass valve used to relieve pressure during start up to provide easy, low effort starting.
Gas powered pressure washers provide more power, flexibility and cleaning speed than electric powered models.
Not necessarily. Most pressure washers are not designed to be used in this manner. Lake water contains sediment and other materials that can clog the unit. Siphoning water from a holding tank with a machine not designed for siphoning will severely damage the pump. Siphoning requires a heavier pump complete with special fittings.
NEVER hook any pressure washer to a hot water supply. Doing so immediately voids the warranty and ultimately damages the pump.
