What is the flow rate of a pressure washer?
It refers to the flow rate or the volume of water that moves through the pressure washer’s nozzle every minute. Think of GPM as rinsing power. The higher a pressure washer’s GPM, the quicker you can wash a surface clean. The GPM of effective commercial pressure washers ranges from 2.2 to 10.
How do you rate a pressure washer?
Pressure washers carry two ratings that reflect their cleaning power: pressure, which is measured in pounds per square inch (psi), and water flow rate, measured in gallons per minute (gpm). A machine with lower ratings can do almost all the jobs a more powerful machine can do.

How many gallons per minute does a pressure washer use?
As mentioned above, pressure washers only average around 2-4 GPM of water consumption. That’s about the same as the sink in your home which averages around 2.2 GPM. Compared to a hose which puts out 24 GPM. The low GPM and powerful quick cleaning means less overall water usage.
Are pressure washers adjustable?
