Water spraying from a pressure washing hose

If you want the best outcome when you are pressure washing, it’s important take a closer look at your machine’s washing settings first. Cleaning the dirty surface of a driveway, deck, and other parts of your property requires the right amount of force, which is where PSI and GPM come in. These are terms to describe the pressure and flow of the water, allowing you to get the sparkling clean you are looking for. Learn about why PSI and GPM are important for your cleaning needs!

Defining PSI

According to Hotsy Water Blast, “PSI stands for pounds per square inch. It refers to the intensity of the pressure with which the machine sprays.” If a machine has a high PSI setting, it’s more likely to lift grime from the surface. Commercial pressure washers have higher PSI’s that can range anywhere from 2,000 to 3,000. For residential washers, they tend to be lower than 2000 and can be handled by the average homeowner.

Defining GPM

“GPM stands for gallons per minute. It refers to the flow rate or the volume of water that moves through the pressure washer’s nozzle every minute”, states Hotsy Water Blast. After buildup of dirt and grime has been removed, it needs to be rinsed away. You can adjust the GPM and quickly rinse away any particles or leftover debris. Cleaning detergents may also be added to the water to remove dirt more easily.
