Introduction
It’s not just about how much power your pressure washer has, but how much water it uses and how powerful it is.
What do all of these numbers on the pressure washer mean?
PSI is the most common measurement of pressure. It stands for “pounds per square inch.”
When you see a pressure washer with a PSI rating of 2000, it means that when you use the machine, it will be able to produce up to 2000 pounds of force per square inch (2 x 1010 N/m2). The higher this number is, the more powerful your pressure washer will be.
GPM stands for gallons per minute and measures how much water flows through your hose at any given time. If you have a powerful motor but little water flow, then what’s the point? Luckily, GPMs are often listed alongside PSIs so that consumers can compare them side-by-side when shopping around—and they just so happen to relate directly!
How much pressure do I need?
PSI and GPM are the two most common pieces of information for power washers. PSI is the pressure per square inch, and GPM is the volume of water per minute.
A higher PSI means more power, but also more water use. You’ll have to decide what’s right for your project and your budget.
How much water does a power washer use?
What do you use to measure how much water your power washer uses? Is it gallons per minute (GPM)? No, that’s not right. Oh, wait… is it pounds per square inch (PSI)? Nope! If you’ve ever wondered why you can’t get a straight answer on this topic, there’s a good reason: GPM and PSI are two different things.
The “gallons” part of GPM refers to the amount of water flowing through the hose; the “pounds” part refers to how much pressure that flow of water is under. Both measurements work in tandem with one another: if your pressure washer delivers 2000 PSI but only pumps out 1000 GPM through its “gallon” hose, then its performance will be limited by having too little pressure relative to how much liquid is flowing through it at any given time (in other words: less than 1/2 gallon per minute).
How often should I power wash my driveway?
If you want to power wash your driveway every year, that’s fine. The more often you do it, the better your driveway will look. But if you don’t have the time or money to keep up with it regularly, then once every few years is fine too.
If you’re wondering how often should I power wash my driveway? Well…it depends! It depends on how dirty it is, how much time and money you want to spend on maintenance and how often do people see your home from a distance or close up in their cars as they drive by (this can be helpful information for marketing purposes).
You have to know the GPM and PSI, not just the PSI, to know how powerful a pressure washer is.
You have to know the GPM and PSI, not just the PSI, to know how powerful a pressure washer is. The GPM is gallons per minute and it determines how much water you use. The PSI (pound per square inch) measures how much force can be applied to an object through water pressure.
Conclusion
We hope this guide has helped you understand the importance of choosing an appropriate pressure washer for your driveway. As you can see from all of the information above, there are many factors to consider when choosing a machine that will work well with this type of surface. Taking into account all of these factors will help ensure your investment is worthwhile and will last for years to come!
