Chemical hose: Feeds cleaning agents into the pump to mix with the
water. Refer to Chemicals and Cleaning Solvents.
Chemical injection system: Mixes cleaners or cleaning solvents with
water to improve cleaning effectiveness.
CU: Cleaning Units. GPM multiplied by psi. (GPM x PSI = CU)
GPM: Gallons Per Minute. The unit of measure for the flow rate of
water.
PSI: Pounds per Square Inch. The unit of measure for water pressure.
Also used for air pressure, hydraulic pressure, etc.
kPa (kilopascal): Metric pressure measurement. 1 kilopascal equal
1000 pascals.
Quick-connect spray wand: Allows the user to quickly change out
high-pressure nozzles. Refer to Spray Wand Nozzles.
Thermal relief valve: When the temperature inside the pump rises
too high the valve will open and release a gush of water in an effort to
lower the temperature inside the pump. The valve will then close.
Water supply: All pressure washers must have a source of water. The
minimum requirements for a water supply are 20 psi (138kPa) and
5gallons per minute.
