What are gas pressure washer ratings - and what do they mean?
There are two universal ratings that are used to designate the power, cleaning ability & efficiency of any gas power washer - and to help consumers accurately compare models.
So, when you're shopping for a gas pressure washer, these ratings will help you compare models - to save you time & money! So lets review these ratings............
The first universal pressure washer rating is PSI or Pounds per Square Inch.
PSI represents the pressure, or force, of the water that the pressure washer pump is able to produce. The higher the PSI of a gas pressure washer, the stronger the force of the pressurized water. And the higher the PSI rating, the more cleaning power you'll have to finish your outdoor cleaning projects faster.
You'll find gas units on the market, for homeowners, with varying PSI ratings: generally from 2,200 to 4,200 PSI.
If you're thinking about doing some paint stripping, you'll really need a PSI rating of 3,000 or more. Personally, for the fastest cleaning power and strength, I like units, like mine, that have a rating of 3,000 PSI.
The second universal rating is GPM or Gallons per Minute.
GPM means how fast the water flows through the gas pressure washer. The faster the GPM, the better cleaning power you'll have.
Since you'll probably end up spending $300 to $600+ for a new quality unit, here are a few more important buying tips in addition to comparing gas pressure washer ratings:
As you shop, remember to check the pressure washer engine. And compare the quality of engines on the models you're looking at.
You'll see generic, no-name engines and brand name engines. And you'll probably notice that units with the brand name engines like Honda, Briggs & Stratton, Kohler, Subaru and Generac are priced a little higher than the no-name engines. Yes, brand name engines are priced a bit higher, but they are better quality & will have a longer working life. And, usually, provide a better warranty, if anything should go wrong.
Also, my advice is to pay attention to the brand and quality of the pump. The pump is responsible for putting the power & pressure into the water - so its the hardest working part of the pressure washer unit.
95% of the pumps on units for homeowners are axial cam pumps. You'll see units with generic, no-name pumps or brand name pumps like Comet, CAT, General, AR, etc.
Again, units with brand name pumps cost a few dollars more, but they are more reliable, have a longer working life and generally have much better warranty protection.
Now, armed with knowledge about universal gas pressure washer ratings and important engine & pump information, you'll be able to make a great choice as you shop around.
