What Is A Gas Pressure Washer?
A pressure washer is simply a piece of equipment with an engine or motor turning a pump to push water through an orifice. Via such a small hole, the water is fast-moving enough to blast all the dirt and grime.
More water means higher pressure, and then faster water speed, facilitating the removal of dirt from the surface that needs cleaning.
Compared to electric powered pressure washers, the gas model is portable with wheels. They are bulkier, but that’s okay.
Such appliances require routine maintenance to stand the test of time. They are also more expensive, but given their extreme power, it’s well worth your investment.
How to Choose the Best Gas Pressure Washer?
You may get confused with thousands of the best gas pressure washer reviews out there. To save you from such hassle, we’ve picked out a few critical criteria that demand your consideration before making a purchase.
Otherwise, you may end up wasting your money and buying the wrong one.
Between cords with the most influential electric pressure and smooth mobility without compromising on the power: Which one do you prefer?
Even the best gas pressure washer asks for regular maintenance, including fuel loading, oil changing, and level examination. The more powerful a machine is the higher power it consumes. Therefore, electricity and water need to stay in the store at any time.
It’s crucial to think about the whereabouts of using pressure washers. Is the ground accessible or not? Low models can’t deal with rough terrains.
If possible, you should invest in a washer with a welded frame, which helps maintain the pump and the engine intact.
Water pressure strength
Depending on which items or areas you intend to clean, there’re various levels of power to choose. A domestic cleaner will do well on common surfaces such as siding, patio, driveways, or decks.
However, units with higher GPM and PSI are effective in stripping the paint, cleaning built-up much and mildew as well as heavily-embedded moss.
PSI and GPM Output
PSI, or Pressure on Square Inch, is the measurement of the water pressure strength produced by the machine.
The higher the PSI is, the more effective the tool is. In other words, models with a high PSI tend to cover heavy-duty projects while lighter tasks such as washing cars or cleaning pool patios only require the support of a low-PSI washer.
On average, a commercial-grade power washer can produce a sufficiently high PSI number to deal with paint stripping, siding cleaning on a multi-story house, and so on.
GPM, or Gallons per Minute, indicates the number of water gallons flowing through the pressure washer per minute. It is in proportion to the power of water output.
The GPM determines the speed of the machine to wipe away dirt and grime, and then rinse the desired cleaning surface. Don’t go for a washer with a high GPM as long as you can afford reliable or consistent water pressure.
You’d better consider both figures when deciding on a gas pressure washer. A medium unit comes typically with a low GPM and high PSI output.
Different pumps will deliver different output. It’s best to choose reparable ones with a long operation period.
Pay attention to the room of accessories like nozzles, hose, wand, and attachments. Make sure you can quickly put them on the pressure washer. Otherwise, you may end up searching this and that for those items after every winter.
Gas powered pressure washers cost from hundreds to thousands of dollars, depending on power or advanced features. Prepare to incur an enormous sum of money for a sturdy unit with a more massive pressure output along with cleaning power.
