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.

Is 2.5 gpm enough for pressure washer?
How to choose the right GPM for a pressure washer depends on the size and difficulty of the cleaning job. If you’re working a large area or on really stubborn stains you’ll want a washer that has a high GPM. For smaller jobs or simply cleaning projects a washer with moderate GPM output is sufficient.
What does gallons per minute mean?
GPM means Gallons Per Minute. Also known as “flow rate”, GPM is a measure of how many gallons of water flow out of your shower head each minute. This means no more than 2.5 gallons of water should flow out each minute.
Do pressure washers use lots of water?

How much water pressure does a power washer need?

How much water does a washing machine use?

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.
Is PSI or GPM better?
Generally, contractors or professional cleaners will find that they prefer a higher GPM machine over PSI since they use cleaning solutions to loosen grime instead of relying fully on PSI, their job primarily becomes one of rinsing the dirt away. The higher the GPM the faster it will be to clean large surfaces.
Can you clean 2.3 gpm concrete?
Contractors recommend 5 to 6 GPM for concrete. Cleaning speed can also be increased by using a rotary nozzle.
What is more important in a pressure washer PSI or GPM?

How do you calculate gallons per minute?
The formula to find GPM is 60 divided by the seconds it takes to fill a one gallon container (60 / seconds = GPM). Example: The one gallon container fills in 5 seconds. 60 / 5 = 12 GPM. (60 divided by 5 equals 12 gallons per minute.).
Is 1.5 gallons per minute a good well?
A standard 6-inch diameter drilled well can store 1.5 gallons of water per foot. The Water Well Board suggests that the minimum water supply capacity for use inside a home should be at least 600 gallons within a two-hour period, or about 5 gallons per minute for 2 hours.

Do power washers use a lot of electricity?
Electric power washers commonly draw 12.5 amps when operating; the better ones include tighter internal machinery to produce more pressure at the nozzle. At a voltage of 120 volts, the power consumption equals 12.5 amps times 120 volts, or 1,500 watts (1.5 kilowatts) per hour.
Where do pressure washers get their water from?
A pressure washer is less sophisticated than it sounds. It’s really just a water pump powered by an electric motor. The washer takes in ordinary water from a faucet (that’s a tap to you folks in the UK), the pump accelerates the water to high pressure, and then squirts it from a hose at speed through a trigger gun.
