So why should you take our word for it?

Before we get to the nitty-gritty, you might wonder why you should rely on our opinion before making a purchase. We understand and consider most people’s needs for a home pressure washer.

Here’s why you can trust us and how we arrived at the best gas pressure washer for most users:

Our experience

We know what a challenge maintaining and caring for a home and finding quality tools for your budget is like. We do it ourselves! To help you avoid buying a lemon-like, we all have – we take the time to review the best tools and do all the homework for you.

Our practical knowledge

You’re not reading reviews by someone who’s never had their hands on a machine. We use and care for our pressure washers and other equipment. We know what has worked well and what has left something desired.

We want to help you find the best pressure washer for you.

As we said, we don’t want you to get stuck with a lemon. That’s a nightmare. Instead of forcing you to figure it out through trial and error, we’d rather go through that ourselves.

You can be confident that you’ll find at least one great gas-powered pressure washer for you in the following gas pressure washer reviews, even if it isn’t our favorite.

Do I need a gas pressure washer?

Assuming you accept that you need a residential pressure washer, you may be bouncing back and forth now on gas or electric.

Electric certainly is less expensive. However, suppose you only need to lightly wash some patio furniture and a few small windows on a one-story house. In that case, you can probably get away with an electric model.

You’ll want a gas-powered model, though, where the rubber meets the road. They deliver almost twice the water pressure of any electric pressure washer, making the job faster and easier.

Cleaning the siding will be easier with higher pressure if you have a large, tall house because you’ll maintain enough force up at the top to do the job. Think about those tricky spots under the eaves.

Lower pressure on a two- or three-story house isn’t cut it. So we have written an article on cleaning a two-story house with a pressure washer

Adequate water pressure also blasts off dirt and stains in concert much more quickly. Gas power washers clean three times as fast, according to Consumer Reports.

Suppose you’re cleaning a large driveway, outdoor furniture, patio, lawn equipment, RVs, boats, grill, and walkway. In that case, this adds up to significant time savings. An all-day – or three-day-long – affair with an electric power washer will be cut into a third.

How do I find out the best gas pressure washers?

Look around outside your home and note what needs a deep cleaning. Driveways, patios, decks, porches, siding, windows, and outdoor furniture all get a bit grimy over time.

After making your list, you’ll better know the best gas power washer to fit your needs. When talking about home use, we typically talk about these in terms of light-, medium-, and heavy-duty.

These broad terms include a range of pressure and output measured in pounds-per-square-inch (PSI) and gallons-per-minute (GPM).

If your cleaning needs are minimal, look for a light-duty pressure washer. The PSI tops out at 1,900 for these models, with 2 GPM. You’d use one of these if you’re cleaning a small deck, some patio furniture, and a little light grime on a small house.

Most people’s uses will fall into the medium-duty category. For example, you can efficiently clean up an average-sized house, fences, and driveways. The PSI ranges from 2,000 to 3100 psi. The max GPM is 3.

If you have a farm, a two-story house, or a shop, you’ll want to find a heavy-duty pressure washer. 2,800+ PSI and 2 to 4 GPM help you blast through your chores.

What to Consider When Shopping for the Best Gas Pressure Washer

Gas Pressure washers, unlike electric ones, are more powerful and may be used for various tasks. Consider the intended application, portability, features, and price when choosing a gas pressure washer.

Intended application

Gas pressure washers are ideal for cleaning various objects, including cars, boats, patios, driveways, siding, and grills.

Choose a model designed for the specific cleaning applications you have in mind.


When purchasing a gas pressure washer, the three most important things to consider are PSI (pounds per square inch), GPM (gallons per minute), and cleaning power. The PSI and GPM determine the machine’s cleaning capacity. The higher the PSI and GPM, the more powerful the machine. CU (cleaning units) is a technical term that refers to the combination of PSI and GPM. It’s an excellent method to compare how various effective versions are.


Some pressure washers are easier to move around than others. If you plan to use your pressure washer at different locations, choose a lightweight model with wheels for easy transportation.

Build Quality

When looking for a gas pressure washer, look for one with the excellent build quality. Choose a model made of high-quality materials and has a sturdy design.

Detergent Injection

Some pressure washers have a detergent injection system that allows you to add detergent to the water stream. This feature helps clean tough stains.


A variety of nozzles are included with all pressure washers. Select a machine with the precise nozzles you need for your planned application.


If you plan to move your pressure washer around, choose a model with wheels for easy transportation.

Hose Length

The hose length will determine how far you can move around using the pressure washer. If you plan on cleaning large areas, choose a model with a long hose.


Gas pressure washers range in price from $200 to $600. Choose the one that best matches your budget and cleaning requirements.


Choose a model that comes with a good warranty. It will ensure that you are covered in case of any problems.

The most effective gas pressure washer options have been carefully curated to meet the demands of today’s professionals. Check out our top picks to see which one is right for you.

Gas Pressure Washer Reviews – The Top Picks

Here are the gas pressure washer reviews to help you find the perfect one.

Simpson Cleaning MSH3125 MegaShot – Best overall

Last update on 2024-05-15 / Affiliate links / Images from Amazon Product Advertising API

Simpson Cleaning’s MegaShot pressure washer is one of the best-rated gas pressure washers in the heavy-duty category. The Honda GC190 residential engine powers 3,200 PSI and 2.5 GPM.

Welded steel construction frames out a solid, sturdy piece of equipment. So you end up with a lean, mean cleaning machine for a surprisingly economical price.

With your washer pressure, you get a 25 feet kink-free hose, ergonomic spray gun, and five stainless-steel quick-connect nozzles. In addition, a small clear hose is attached for detergents instead of a tank to dump soap into.

You’ll also notice clips and books for keeping all the accessories bundled when not in use.

Simpson Cleaning touts a range of warranties on the components of their equipment. For example, the Honda engine has a 2-year warranty, while the axial cam pump and frame have a 1-year and 5-year warranty, respectively.

Your accessories only have a 90-day warranty. However, if you receive damaged accessories, Simpson Cleaning is happy to replace them promptly.

The MegaShot may not be as pretty as some models, with no plastic covers. Still, that minimalist functionality is your best friend in a hard-working tool. Unfortunately, all those little plastic details are one more thing to break or snag.

It would have to be the wheels if we hit the MegaShot with a downside. Most pressure washer models turn to never-flats to save you from replacing tires.

If your pressure washer is used around the shop, you know how easily a nail can get run over. Is it a dealbreaker? Not at all. You’ll even appreciate the pneumatic tires if you have to go over bumpy terrain in your yard.


  • Starting the engine is super easy. Just one pull is usually enough.
  • The 3,200 PSI offers enough power that some jobs don’t need detergent.
  • Simpson Cleaning starts and tests every engine to ensure a quality, functional product.
  • Brass fittings and an abrasion- and kink-free hose ensure a long lifespan.
  • At 65 pounds, most users will have no problem rolling the MegaShot around.


  • There’s a lot of vibration when the engine is running.
  • The short handle makes it more difficult for tall users to move their washers.

WEN PW3100 Pressure Washer – Best for Concrete 

Last update on 2024-05-14 / Affiliate links / Images from Amazon Product Advertising API

WEN has made a bit of an easier-to-use high-pressure washer than the MegaShot from Simpson Cleaning. As a result, the PSI is slightly less, at 3,100, but the 208 ccs 4-stroke engine is powerful.

Other upgrades over the MegaShot include a more extended, 30-foot hose and prominently labeled quick-connects for the nozzle attachments. If the siphon hose for soap were an issue for you on the MegaShot, you’d also appreciate the built-in soap tank on the WEN. The 41″ high handle is also a perk, especially for taller users.

WEN backs the PW3100 with a 2-year warranty on the entire machine. In addition, if you experience problems requiring repair, they work with a network of repair technicians nationwide.

The price tag on this high-pressure washer is almost stupidly low for a gas-powered one. The quality of the steel and engine more than justify the money.

Most people found a reliable, budget-friendly tool in the WEN. Perhaps not surprisingly, since WEN is a U.S. company with an excellent reputation.

For those who pay close attention to the maintenance of your equipment, the fuel shut-off valve is a nice feature. The fuel flow is turned off to the engine when you close it.

When you’re done with your work, stop the fuel flow, wait until the engine starts to choke, then turn off the machine. Doing this prevents gasoline from standing in the carburetor, meaning you won’t have to clean it out a few times during the life of your pressure washer.


  • The 3,100 PSI and 2.5 GPM rating make most chores take very little time to complete.
  • 12″ plastic never-flat wheels roll very easily across most terrain.
  • The spray nozzles, frame, and wand are all metal, and the brass connections will withstand extended use.


  • The 75-pound weight of the PW3100 may prove too much for some users, particularly senior citizens who want light equipment.
  • Some of the parts can break, especially the clips for attachments.

Simpson Cleaning PS3228 PowerShot – Best gas pressure washer with honda engine

Last update on 2024-05-15 / Affiliate links / Images from Amazon Product Advertising API

By now, we’re pretty familiar with Simpson Cleaning. Their PowerShot pressure washer is the big brother of the MegaShot and is one of the top gas pressure washers. It rolls in with 3,300 PSI and the same flow rate of 2.5 GPM.

This Honda engine is the GX200, a more powerful option than the previous model. However, be sure to consider that it weighs 83.5 pounds – this is not a lightweight tool.

You’re more likely to need this bad boy if you’re a contractor or have a huge house to clean. Be careful using it on surfaces you don’t want to remove the paint because that is what it was designed to do. On the other hand, the power is impressive for projects where you want to strip and refinish.

It has a 90-day warranty on the accessories. Every other warranty is longer and covers more on this unit.

The Honda engine has a 2-year warranty, which is ample. Still, Simpson Cleaning expects great things from this pressure washer based on the warranties offered on the pump and frame.

The pump’s warranty is five years – impressive. The 10-year warranty on the frame is just outstanding.

The same 25-foot high-pressure hose comes with the PowerShot and five spray nozzles. It includes the soap nozzle. Speaking of soap, Simpson Cleaning still doesn’t offer a detergent reservoir on the PS3228. You’ll have to dip the siphon line in a tub of soap, just like before.


  • It has severe water pressure, more than ample enough for home use.
  • The triplex axial cam pump is an absolute workhorse.
  • This machine can be used as a commercial pressure washer.
  • For a commercial application and engine, the cost is pretty affordable.
  • The parts are made and assembled in the U.S.A., even the Honda engine.


  • The 25 feet of hose runs out very quickly while you’re working.

Generac SpeedWash 7122 Pressure Washer

Last update on 2024-05-15 / Affiliate links / Images from Amazon Product Advertising API

Most people know Generac from their portable job site generators and home emergency backup generators, and now they’ve made it to our gas power washer reviews. Delving into pressure washers is a move that makes sense for Generac, given their experience with small engines.

The SpeedWash 7122 lives up as a powerhouse. The focus on increasing labor efficiency is impressive. Cleaning time is improved by up to 50%. The power dial on the spray gun that allows you to tune the pressure to the appropriate level for the material you’re cleaning is also remarkable.

For instance, you can lower the water pressure to wash your car without damaging the paint or crank it up to blast mildew off the concrete.

Only four nozzle tips are available with the Generac, but you may not miss that 10° spray tip. Rather than a bunch of nozzle tips, Generac has focused on accessories to help your chores get done correctly.

These accessories include a power broom, a turbo nozzle to spray 30% faster, and a soap blaster that shoots soap three times as far as the regular soap nozzle. In addition, a 30-foot hose that resists kinking and marring is included with the pressure washer.

It is easy to forget the basics with all the other striking features. The SpeedWash 7122 has the highest flow rate we’ve seen so far, with 2.7 GPM. It is coupled with 3,200 PSI for serious cleaning capability. Powering all of this is Generac’s 196 cc engine.


  • The pressure dial on the wand is hands down the best feature on the Generac.
  • The additional attachments provide a lot of bang for the buck.
  • There’s enough cleaning power to reach second-story siding.
  • The oscillating spray pattern of the turbo nozzle removes grime and paint quickly.
  • The SpeedWash 7122 has outstanding fuel economy – around 5 hours on a single gas tank.


  • The unit sometimes vibrates pretty hard, causing it to walk around.

Champion Power Equipment Dolly-Style Pressure Washer

Last update on 2024-05-15 / Affiliate links / Images from Amazon Product Advertising API

Despite its unassuming name, this machine boasts a 224 cc engine from Champion. That engine is pushing 2.4 GPM at 3,200 PSI. Not too shabby, especially since this unit is one of the lighter models we’ve reviewed.

Champion Power Equipment has done its best to consider the practical side of its cleaning power washer. They included a 4-foot lead hose to siphon detergent and two 1/2-gallon soap tanks on the unit.

You can store nozzles, hoses, and spray wands on their docking stations. In addition, the dolly handle and never-flat wheels are a relief from the bending and lugging involved in some other models.

Champion Power Equipment’s power washer is a good fit for those of you who live in California. Unlike the WEN PW3100, this pressure washer meets those emission standards set out by California and is EPA certified.

With a 2-year warranty and lifetime technical support, Champion Power Equipment is ready to stand behind its products and ensure customer satisfaction. However, suppose you have any issues with your equipment. In that case, they have a network of service centers specializing in small engine repairs to get you back up and running.


  • The owner’s manual is surprisingly well written and easy to follow. It has all the information you need in an easy-to-find format.
  • A single gas tank lasts for around 5 hours; you may even wriggle a little more time out of it.
  • The following is a simple pull-starter that only requires one pull.
  • Customer service is prompt if you have mechanical issues or operating questions.


  • The muffler gets extremely hot and is by the gas cap. You must be very careful when adding fuel after running the unit for a while.
  • The cost of this pressure washer is on the higher end, especially with no genuine accessories.

A-iPower APW2700C – Best budget gas pressure washer 

Last update on 2024-05-14 / Affiliate links / Images from Amazon Product Advertising API

If the other pressure washers on the list have been a little more than you want to spend, the APW2700C will make you a lot happier. Sure, it has the least PSI we’ve seen at 2,700 and the lowest GPM with 2.3. That’s not a bad thing, though. If you don’t need a monster power washer, you don’t want to pay for the extra oomph.

The three quick-connect nozzles and 25-foot hose are probably more than enough for a medium-duty pressure washer. In addition, there is a siphon hose for soap to help you clean off gunk that this unit may not have the power to blast off with force alone.

The engine is a Predator 196 cc engine with6.5 horsepower. It doesn’t have the reputation of the Honda or Generac engines, but it is enough to run this machine. Those other brand names command a higher price; the APW2700C couldn’t be sold at the same affordable level if it used a different brand.

A 2-year warranty backs the whole setup, which is probably the closest thing to a “premium” aspect of A-iPower’s machine. The small .95-gallon fuel tank means frequent refills. Think every two hours. You’ll need to plan accordingly.

Again, this is not a heavy-duty machine intended for rugged, prolonged use. However, if you only want to clean your house and vehicle once in a while, it should be all you need.


  • The price point is very affordable for almost any budget.
  • 2,700 PSI is more than enough for basic household chores for most homeowners.
  • Weighing in at 62.9 pounds, most people can quickly move the pressure washer around their home.
  • No significant problems have been reported from damage during delivery.


  • The 8″ never-flat wheels are too small to easily roll over bumps or divots.
  • Only three nozzles are available without an additional purchase, meaning specialized jobs will require you to buy more nozzles.

Generac 6922 Pressure Washer

Last update on 2024-05-15 / Affiliate links / Images from Amazon Product Advertising API

If you want the Generac name but without as much bite as the SpeedWash 7122, the 6922 is probably up your alley. Great for general home use, you’re getting a severe tool to make your chores easier. 2.4 GPM flow rate and 2,800 PSI will clean your siding or deck without overkill.

Generac’s 6922 doesn’t have all the excellent attachments standard with the SpeedWash. It does, however, have four quick-connect nozzles and a 1/2-gallon soap tank onboard. In addition, the 25-foot hose is right on par with most models.

You do have the option to purchase that excellent power broom separately if you want it. However, you may balk at spending any more on your pressure washer at this price point.

The best feature for your comfort is the ergonomic extra-large cushioned handle on the spray gun. You aren’t forced to squeeze a little trigger for hours while working. The meager 57 pounds the 6922 weighs is also a back saver on a long day.

Generac’s 2-year warranty covers parts, the engine, and the frame. Unless, of course, you intentionally mess something up. Treat them fairly, and they’ll treat you fairly as well. Customer service is usually on top of it if you have a complaint or some piece of your pressure washer has busted.

Most of the time, they promptly send you replacement parts or help you get a hold of their closest service center to repair any issues.


  • 2,800 PSI is enough to lift dirt and mildew easily from most surfaces.
  • Most of the assembly has been done; just a little work on the handle, some fuel, and oil, and you’re ready to go.
  • 10″ never-flat wheels move quickly over the yard.
  • The horizontal shaft engine and pump are on the same level, connecting hoses is a breeze, and the machine is well balanced.
  • Tough enough for residential or small farm use.


  • The stiff hose can be challenging to maneuver.
  • The PSI is insufficient to clean a 2-story house effectively.

Ford 2,700 PSI Gas Pressure Washer

If you want a pressure washer that looks like you’re ready to banish grime from your property forever, you should go with the Ford model. Want to rub it in the nose of Bob down the road, which always has the fancy equipment and perfect yard?

Again, go with the Ford. No shame; we want you to win the neighborhood war.

The 180-cc engine is not the largest we’ve looked at, nor are the 2,700 PSI and 2.3 GPM. It also comes with just three quick-connect nozzles and a 25-foot hose. So what are you getting with the Ford, besides an excellent paint job and a logo?

Ford’s pressure washer is about the name. Ford is well known for quality engines and machines, whether in your vehicle or shop. But, unfortunately, you’re investing in their top-rated reputation, and the price on that can be high.

Before thinking the brand is the only good aspect of this power washer, remember the fold-down padded handle and 10″ never-flat wheels. Okay, maybe remember the brand, too, because the wheels are designed to look like the rims on Ford’s F-150. You just won the Battle of the Awesome against Bob.


  • The onboard soap reservoir eliminates extra hoses and a tub for detergents.
  • The folding handle makes a more compact profile for more accessible storage.
  • Pulling the handle back out raises it to a very comfortable level for the average user.
  • Sixty-six pounds of weight allows you to move the unit as you work quickly.


  • The whole system is proprietary; you cannot use aftermarket pieces or adapters with it.
  • The noise level is pretty high.

Craftsman CMXGWASO21021 Pressure Washer

Last update on 2024-05-13 / Affiliate links / Images from Amazon Product Advertising API

Craftsman has a long reputation for cheap but reliable tools. Their pressure washer lives up to the legacy. In addition, they’ve made a friendly little medium-duty power washer with some thoughtful details.

The flexible, 25-foot hose hook is intelligent under the handle. Also innovative are the slots for the four quick-connect nozzles in the plastic billboard. The billboard also features a strap to keep your pressure washer anti-freeze and lubricant bottle in an easy-to-use location.

No worrying about forgetting to use it or losing it in the sea of bottles in your garage. 10″ never-flat tires are featured for maneuverability without maintenance.

The 163 cc Briggs & Stratton engine is what you expect to see with Craftsman. The ReadyStart engine starting system is another sweet feature. If your engine doesn’t start in a maximum of two pulls every time, an authorized Briggs & Stratton service technician will do the repairs at no charge.


  • Craftsman’s pressure washers are made in America, albeit from globally sourced parts.
  • A generous 3-year frame warranty and a 2-year engine and equipment warranty are provided.
  • A soap reservoir tank and siphon hose are attached.
  • Additional attachments like the circular attachments make a versatile cleaning tool.


  • The hose is not kink-free, making it more challenging to work uninterrupted.

PowerBoss 3100 PSI Pressure Washer, Powered by Honda

Last update on 2024-05-05 / Affiliate links / Images from Amazon Product Advertising API

Back into heavy-duty pressure washers, the PowerBoss is as mean as it sounds. Unfortunately, the price tag is, but you get what you pay for.

In this case, you’re paying for 3,100 PSI and 2.7 GPM powered by a 187 cc Honda GC190 engine. You also get a 1-gallon detergent tank, four quick-connect nozzles, a 25-foot hose, and 10″ pneumatic wheels—all standard inclusions for any quality pressure washer.

If you purchase the PowerBoss for commercial use, note that the warranty is only 90 days. For residential customers, however, it’s two years.

The possible 90-day warranty may alarm you less when you consider that PowerBoss had all its units tested at an independent lab. In addition, the Pressure Washer Manufacturer’s Association certified them, and all the specifications are verified as accurate before making a purchase.

Given the size of the engine and the water pressure, you expect a beefier machine. So it’s surprising to learn that the PowerBoss only weighs 62 pounds.

That makes it a perfect choice for homeowners who need more power than the other lightweight models we’ve reviewed. So again, you’re striking a balance between a manageable size and job-appropriate PSI.


  • The Honda engine is ultra-reliable and runs excellent with proper maintenance.
  • You can easily log more than 100 hours of use without noticing a decline in performance.
  • The nozzles can become gentle enough for cleaning the barbeque grill or furniture.
  • Strong enough for heavy use on a farm.


  • The 25-foot hose is prone to kinking and scuffing.
  • Sometimes the connection at the wand and hose develops a link; you’ll need a plastic o-ring if it does.

Stanley SXPW2823 Pressure Washer

Last update on 2024-05-15 / Affiliate links / Images from Amazon Product Advertising API

While not the most inexpensive pressure washer on the list, the Stanley SXPW2823 certainly comes close. You get more bang for your buck over the A-iPower pressure washer. For example, four quick-connect nozzles are included instead of three, plus a bonus Turbo nozzle that shoots oscillating water for a scrubbing effect.

The welded steel frame has been powder coated to prevent corrosion. This machine is backed up with a 5-year warranty for the frame. The engine, a Stanley overhead cam engine, features a 2-year warranty. Unfortunately, the pump, which will always wear out before the engine, only has a 1-year warranty.

Unlike some models we looked at, the 25-foot hose is kink- and abrasion-resistant. Paired with the hose is a spray wand that is comfortable in your hand and features an adjustable pressure regulator. The time savings from the adjustment knob is tremendous.

Don’t expect a light machine with the Stanley. Although not the heaviest on the roundup, it does come in at 71.8 pounds. You’ll notice that weight when you’re moving it around for a full day of work.

2,800 PSI at 2.3 GPM lends itself to moderate work around the house. You won’t be cleaning the eaves of a two-story or a larger home, but you will get done a lot of chores all the same. The driveway, patio, and a good-sized deck can all be easily tackled with the Stanley.


  • An excellent price for a medium-duty pressure washer.
  • Large never-flat wheels can roll around the yard without much difficulty.
  • Siphon hose for using detergents ups the cleaning capabilities of this pressure washer.
  • The pressure regulator in the wand is convenient and just awesome.


  • The fuel economy is not excellent. Except to run out and have to refuel every couple of hours.
  • The water pressure is not sufficient to clean in high places.

The Most Sold & Loved Gas Pressure Washer Brands

What kind of gas does a pressure washer use?

Some people are purists about machines, and that’s awesome if you are, too. But, unfortunately, your small engine will probably outlive us, then.

It can seem a little confusing for those who aren’t as careful or knowledgeable about what goes into our pressure washers. Do I use regular gasoline or some high-octane stuff? Do I need to buy one of those tiny gas bottles from the hardware store?

The good news is, yes, you can use regular old gasoline for your pressure washer. However, I don’t think you’re doing it a favor buying ethanol. You’ll ruin the engine. It’s been designed to run on unleaded gasoline with no more than 10% ethanol.

You can purchase premium, ethanol-free fuel for your pressure washer if you’re one of those guys who likes to keep everything a notch above perfect. Also, unlike a weed eater or chainsaw, you don’t have to mix the gas and oil. Instead, each has its tank for you to fill as needed.

How do I safely run a pressure washer?

Before you do anything, read your instruction manual. Yeah, yeah, we know. But you’ll appreciate being prepared. For instance, if you’ve washed dishes with cold water before, you already know that it requires more soap and effort.

You may think you’ll save yourself a lot of time by cranking up the heat and letting her rip. But instead, what you may end up doing is ruining your new pressure washer if it has been designed to clean efficiently with cold water.

Reading the manual first will warn you about your machine’s specific requirements.

After you’ve thoroughly acquainted yourself with your pressure washer, you can pull that bad boy out. However, it’s a solid idea to grab some eye and hearing protection before you begin.

Debris can fly up into your eyes from the water hitting it, and if you’d use earplugs while mowing, you should consider them now, too. While you’re rounding up your safety gear, bring the detergent and water source you’ll also be using.

Now you’re ready to get going. Add gasoline and oil as necessary to your machine. Fill the detergent tank or put the lead hose into the soap bottle; this step depends on your specific pressure washer. Attach the water source. For most pressure washers, this is a hose, and turn it on.

Most gas engines on pressure washers have a pull start. Pull the handle, and it will crank. If yours is an electric start, all you have to do is push a button. Now pull the trigger and watch the gunk go bye-bye.

One last thing: it may seem like common sense, but don’t point the nozzle at yourself or anyone else. It’s a bad idea that will lead to a bad day. The water pressure is intense enough to strip the paint. You don’t want to experience it on your skin.

Gas Pressure Washer Troubleshooting

This guide will walk you through the steps for resolving pressure washer issues.


  • Low water pressure
  • Water leaking issues
  • Engine/motor turning off while in use And much more.

Low water pressure

If your pressure washer is not producing enough water pressure, you should check the water supply first.

Three things can cause low water pressure:

The water supply is turned off: Make sure the water supply to your pressure washer is turned on. The water inlet valve may be inside your house near the main water shut-off valve.

The garden hose is kinked: Check the garden hose for kinks or blockages. A kinked hose will restrict the flow of water to your pressure washer.

The pump is not priming: If the pump is not priming, it may be because there is air in the system. To bleed the air out of the system, follow these steps:

Turn off the power to the pressure washer.

Turn on the water supply and let the water run through the system for a few minutes.

Turn off the water supply and turn the power to the pressure washer.

Start the engine and squeeze the trigger on the wand to prime the pump.

Water leaking issues

If you notice water leaking from your pressure washer, you can do a few things to troubleshoot the problem.

Check the hose: The first thing you should do is check the hose for kinks or blockages. A kinked hose will restrict the flow of water to your pressure washer.

Check the connections: Make sure that all of the connections are tight. Loose connections can cause water to leak from your pressure washer.

Check the O-rings: The O-rings are located on the fittings and valves. If they are damaged, they can cause water to leak from your pressure washer.

Engine/motor turning off while in use

If this is the case, you can do a few things to troubleshoot the problem.

Check the oil level: The first thing you should do is check the oil level. If the oil level is low, add more oil to the engine.

Check the fuel level: If the fuel level is low, add more fuel to the tank.

Check the air filter: A dirty air filter can cause the engine to turn off. Clean or replace the air filter if necessary.

The best gas pressure washer is

The Generac SpeedWash 7122 is the clear-cut winner when it all comes down to it. The number of accessories you get for the price is a real value driver.

Back it up with the reliability of the Generac name – people trust them to keep the lights on in emergencies, after all – and you know you’re getting a bargain.

While some gas pressure washer reviews touted impressive PSI ratings and engine power, only the SpeedWash is the complete package. That it has enough power for any job the average homeowner throws at it is enough for us. In addition, the ease of use and genuinely intelligent attachments are why we can easily recommend it to any user.
