Things To Consider Before Purchasing The Gas Pressure Washers:

Before you make a purchase, it is necessary to know about certain factors that help you choose the best one, within your budget. We have mentioned them clearly below for your reference.

1. PSI and GPM Output:

Both of these PSI and GPM have to be taken into consideration when you buy a gas pressure washer.

PSI Pressure on Square Inch (PSI) is a measurement that let you know how strong the water pressure is coming out of the machine to clean the surface. So, the higher the PSI value, the more powerful the machine works.

GPM Gallons Per Minute (GPM) will let you know how many gallons of water is flowing through the pressure washer in a minute. Simply, the larger the GPM number, the greater will be its water output.

One can find the most popular gas pressure washers range from around 2000 PSI and 2.0 GPM to 5000 (or above) PSI and 5.0 GPM. But to get the best value and more versatility, choose a washer from a medium and heavy-duty range that comes around 2500 – 3500 PSI and 2.5 – 3.5 GPM.

For cleaning your regular surfaces such as patio, decks, or driveways, you can choose a residential cleaner with medium PSI and GPM. Whereas, look for a washer with higher PSI and GPM value for cleaning heavily embedded moss, build-up grime, and mildew.

Note: If both PSI and GPM output values are high, then it is considered as the best & high-rated pressure washer. Having high PSI with a low GPM output, it is a medium pressure washer. Whereas if both the numbers are low then a pressure washer is considered as a low-rated one.

2. Engine:

The engine is an important part of a gas pressure washer. It is used to power the compressor and thereby aids in developing high pressure for proper functioning of a washer. The more powerful the gas engine, the higher pressure it will deliver.

We generally, find two types of gas engines – a single stroke or two-stroke engine. Check the engine’s quality before its purchase or else simply choose a washer machine from any reputed brand or manufacturers.

3. Nozzle Tips:

The nozzle tip of the hose will offer you different water patterns and thus let you perform various cleaning jobs. So, you will find a number of nozzle tips are available for this gas washer.

Check specifications to know spray nozzles that come with your machine and they may be 3 – 5 quick connect nozzles that come with your unit. You have to know which type of spray nozzle suits for what cleaning purpose (as each type will do a different job).

For this, we are providing a brief outline of the nozzle types. Check it out.

  • This red color nozzle tip will deliver maximum power blast but meant to use at a small surface area. As its sheer power is damaging, it is a quite less commonly used tip.
  • 15° This yellow color nozzle tip will let you perform medium surface stripping. One can use this nozzle tip to prepare a surface for painting.
  • 25° This green colored nozzle tip with its wide spray area will provide gentle cleaning of dust and debris on the outdoor surfaces. It is most commonly used to clean around the garden and home.
  • 40° This white colored nozzle tip with its light spray will offer delicate cleaning, especially for areas like windows.
  • 65° This black colored nozzle has a soaping tip, which makes it perfect for spraying soap and cleaning over large areas.
  • Turbo Tip This black colored tip will leave the hose and rotates the jet of water for cleaning.

Always choose the wider angle of the nozzle to get the wider jet spray and thereby it would be gentle on the surfaces while cleaning. In case, if you select the wrong spray tip, then you may end-up damaging things like your vehicle’s paint.

So, to get rid of this issue, you can use nozzles used to perform various tasks without changing them. Simply, you have to adjust them as required to operate the washer for different cleaning tasks.

4. Washer Pump:

This pressure pump will build the water pressure in the washer. So, the best quality pressure pump is essential to make the pressure washer to work in the best way.

In general, we find two types of pumps in a pressure washer – axial and triplex pump.

  • Axial Pump Suits perfect for smaller jobs. It is easy to use and maintain.
  • Triplex Pump Provides the best performance and thus suits a heavy user, who frequently uses a washer. Though, it is easy to use but requires more maintenance for its proper functioning.

5. Portability:

We generally use gas pressure washer that are meant for residential or light commercial cleaning purposes, which are designed to be easy to use and portable with wheels. Its wheels can be either pneumatic tires (need to inflate regularly) or never-flat tires.

Among these two types of wheels, pneumatic (inflatable) tires are easy to use while moving the washer over different terrain, as it absorbs the vibrations caused by the machine while working.

So, based on your land area, you should use a pressure washer with good size pneumatic tires. For instance, a washer with plastic wheels will work best for patios or decks easily, whereas if the machine has to drag around a lot then choose wheels that match your requirement.

6. Hose Length:

A hose length of a gas pressure washer is essential to consider. As it doesn’t have access to any outdoor extension lead and thereby to have an ease of usage. Most of these washers have a hose length of 25 foot – 30 foot and if you want, upgrade to your desired length.

Also, the hose length may affect the water pressure of the hose. So, the longer the hose length, the slower will be the power/pressure of water coming out. So, it won’t be much difference even having a gas pressure washer with strong jet strength. For general cleaning of patio furniture, then simply move it closer to the outdoor water tap so that the standard hose supplied will be enough.

7. Hot & Cold Water:

In general, most of the washers use only cold water to clean the surface, whereas a few units allow you to use both cold and hot water. With hot water, you can easily clean the grease or tough oil stains. But these hot water systems are quite commonly seen on commercial models with excellent cleaning powers, yet their price range is over $2000.

8. Frame:

Gas pressure washers are heavy in weight when compared with electric pressure washers. A normal residential cleaner will weigh anywhere from 50 – 200 lbs. In case, if weight increases, then its frame should be durable and portable that supports the load and make it easy to transport. It’s best to use a steel frame, which is stronger and has reduced vibration when compared with aluminum. Also, wheelbarrow/trolley frames are easy to move than dolly/hand truck frames.

9. Detergent Tank:

There are several detergents like household laundry detergent/soap to be used in a gas power washer. Make sure to use phosphate-free specialist powders and liquids that are considered the best. Detergent is poured into the pressure washer either with an onboard detergent tank or siphon tube.

  • Siphon Tubes It is easy to use, all you need to pull the detergent straight out of the bottle. Thus, it has less setup and easy to clean up.
  • Onboard Detergent Tank Holds soap or detergent mixed with water and uses it to clean the surface. One can select the capacity of this detergent tank, as per their needs. The commonly used detergent to water ratio is 1:7 for most of the pressure washers.

10. Price:

The gas pressure washers are a bit costlier and their price range will vary, as a few units are available at an affordable price and some are expensive. Its price range will be around $300 – $500. If you need a bit sturdier washer with larger cleaning power and pressure output, then you have to spend more. So, invest them according to their features and sturdiness.

11. Warranty:

For most of us, purchasing a gas pressure washer is a single time investment. Though, a handsome amount is spent to purchase a washer. So, check the durability and warranty of a unit before its purchase. Most of the manufacturers provide at least a 2 years warranty on their product.

Or else simply try our best products explained above, which offers durability as well as the best warranty to have a tension-free, peace of mind. Also, it is a must to look at customer reviews to know about their customer service responsiveness and other issues before buying a product.

12. Build Quality:

Typically, a pressure washer will undergo various adverse conditions and have to use it frequently. So, a high-quality washer (or) a washer with a heavy frame construction is considered most efficient to function for a longer time.

Metal and plastic combination is a quite commonly used material for a gas pressure washer. But most people avoid buying a product made of plastic material. The plastic material is not considered as bad if it has standard quality. So, you have to consider the type of material used for its construction before you make its purchase.

Note – It’s good to check out the user reviews/comments on its build quality and how long it works without any break.

13. Hose Quality and Resistance:

Cheap hoses of some washers will make it messy and brittle easily. So, it is essential to check the hose thickness, quality and resistance before buying them. For this, you have to read reviews and information provided on the site to know all about the hose.

Also, consider braided hose while checking about the hose. Even though high-pressure hoses are durable, but to enhance their durability, braiding makes them highly resistant to kinks, punctures and other damages. You can use any form of braiding but steel braided hoses are considered as best and durable.

14. Oil/Fuel:

The gas pressure washer requires gasoline as fuel to run the machine regularly. Other than gasoline, the unit needs pumps and engine oil, which has to be changed from time – time. Here the pistons move inside to create friction and thus make the engine hot while functioning.

So, to make this friction smooth and to cool down the engine, we need to use oil, which has to be changed when it becomes thin.

There is some all-purpose oil to use in a pressure washer in all temperature conditions, instead of using different oils in different climates. You can choose the best one from multiple engines and pump lubricants in the market.

15. Other Features:

It is nice to have these features in your product but not considered as mandatory. They help you to have the proper and smooth functioning of the unit. Have a look at them.

  • Accessories – You can effectively use a washer that comes with multiple accessories like extension wands, brushes, patio broom or washers. With these multiple accessories, you can easily clean several surfaces. But the machine should have a usable filler cap and easy to use drain plug.
  • Electric Starter – If you’re unable to use a recoil starter of your unit, then use an electric start gas pressure washer. They are available in the market with a price range from $500 – $1000.
  • Echo-Friendly – A gas pressure washer is a bit noisy while operating when compared with an electric one. So, pick a washer that produces less noise/sound, which doesn’t cause sound pollution or irritate your neighbors as well.
  • Brand – Picking a product from a smarter and well-reputed brand is always the best option. Though a less reputed brand may offer striking features on their product, they provide value/working features as an established brand. We picked out the well-reputed brand products on our list.

Tips to Maintain Gas Pressure Washer:

Maintaining a gas pressure washer properly will help to improve its life span and efficiency. Have a look at some tips used to well-maintain your gas pressure washer.

  • Prefer to use clean fuel, which is free from contamination and moisture to make it engine work effectively.
  • Before its storage, you have to disconnect the water inlet garden hose and empty the water. Then turn on the unit and let the spray handle open until the last drop of water has removed completely.
  • Before starting the unit in a cold season, you have to unfreeze the garden hose, sprayer and washer. Simply, move the machine into an indoor or a heated garage to unfrozen water.
  • It is a must to clean the garden hose and water filters regularly to remove dirt and debris and to aid in its proper functioning.
  • Always use the manufacturer recommended oil type for your washer’s engine.
  • There should be a sufficient amount of oil to run the pump and also, it is a must to check the engine oil’s color to know if the oil has to be changed or has to refill the oil in the engine.
