When it comes to investing in a pressure washer, most buyers have numerous common questions. These may include what is a good PSI for a pressure washer, what is GPM, what PSI should i use to clean the concrete, or even can power washing damage concrete.
Well, all these questions relate to one aspect: the required precise pressure to remove all debris and dirt. The users need to know the amount of pressure is required for an electric pressure washer, a multi-duty pressure washer, or a gas pressure washer respectively, as each type of pressure washer may not be the same.
That's why it is important to know how to refer to pressure washer PSI chart, to understand how each different pressure level caters to your needs.
Understanding PSI (Pounds per Square Inch)
PSI is the unit that allows measuring pressure that a power washer delivers for cleansing. The amount of PSI required tends to differ according to what is to be cleaned. For instance, the PSI value for car cleaning should be less than the PSI or pressure needed for cleaning those stubborn floor stains. The exact or a range of PSI required is what the pressure washer PSI chart reveals.
A 1,500 PSI unit might indicate a high pressure to a homeowner for cleaning decks and siding. This pressure is more than a garden hose. On the contrary, this pressure is too less to clean parking areas stained with tar. It would need somewhere around 4,000 and 7,000 PSI.
Usually, gas pressure washers will have a higher value of PSI, and is recommended for users to get this type if you want to use it for heavy-duty cleaning tasks.
