FAQs About Pressure Washer Pumps by PSI

What is a good PSI for a pressure washer?

The best PSI for a pressure washer is one that can help your pressure washer accomplish whatever task you are using it for. In general, consumer-use pressure washers do not require as high of a PSI rating. So if you plan to wash a car, deck, lawn furniture, etc., you only need a max PSI of 3,000. Professional-use pressure washers are often used to tackle tougher jobs such as industrial cleaning or paint stripping, which will require a higher PSI than 3,000. To find the best PSI for your pressure washer, consider what jobs you need the pressure washer for, and that should narrow down your search.

What PSI should my pressure washer pump be?

Your pressure washer pump PSI should match the pressure washer PSI capacity. If your pump and pressure washer are not compatible, you risk serious damage to your machine and could be creating a dangerous situation as well.
