How important is gpm for pressure washers?
PSI and GPM are equally important when choosing a pressure washer. PSI refers to the amount of pressure and GPM refers to the flow. … PSI (pounds per square inch) refers to the amount of cleaning pressure the device can generate. GPM (gallons per minute) is the amount of water leaving the unit.
What is a good flow rate for a pressure washer?
Household pressure washers typically operate at around 120 BAR with flow rates of 6 to 9 liters per minute.
Is 2.5 gpm good water pressure?
If you’re looking for the highest pressure, unless you’re limited by living in California, Colorado, or New York, go for the 2.5 GPM flow rate. Again, this is the maximum flow rate since 1992. … These showerheads have a maximum flow rate of 1.5 GPM. That’s 40% less water flow than the 2.5 GPM flow rate.
Is 3000psi too much for a car?
Answer: If you already have a pressure washer that you think is too powerful to be safe for your car, say a pressure washer of 3000 PSI or more, you can still safely use it but with the right nozzle .

How much PSI does it take to clean concrete?
Which PSI high-pressure cleaner do I need to clean concrete? To effectively clean concrete, use a pressure washer with a pressure rating of at least 3000 psi and a flow rate of at least 4 gallons per minute (gpm).
Is a higher GPM better?
GPM stands for gallons per minute. It refers to the flow of water, or the amount of water that moves through the nozzle of the pressure washer every minute. Think of GPM as dishwashing power. The higher the GPM of a pressure washer, the faster you can wash down a clean surface.
