Pressure washer spray guns guide
BISON’s guide to pressure washer guns is now available! Choosing the right pressure washer gun can transform cleaning jobs for both professionals and homeowners.
A pressure washer gun, also known as a spray gun or trigger gun, is a handheld device that connects to the high-pressure hose of a pressure washer. By compressing water and forcing it through a narrow outlet under controlled conditions, these guns amplify the water’s natural cleaning properties.
BISON pressure washer suppliers offer top-notch pressure washer guns that are easy to operate and durable, ensuring users always get the best application results. In this guide, BISON will cover the various types of pressure washer guns, their basic features, and how to choose the best washer gun for your needs.
Types of pressure washer guns
Household washer guns: These are medium-sized models designed for residential use. They typically have lower PSI (pounds per square inch) and GPM (gallons per minute) ratings, making them perfect for everyday cleaning tasks around your home, such as washing cars, decks, or outdoor furniture.
Industrial grade washer guns: These are heavy-duty models built for commercial or professional use. They can handle higher PSI and GPM ratings, allowing them to tackle tough cleaning jobs like removing paint, deep-set grime, and even graffiti.
High-pressure washer guns: These are designed to deliver a powerful, concentrated stream of water. They’re excellent for hard-to-reach areas or stubborn dirt. Some of our high-pressure models come with quick-release features for easy nozzle changes.
Washer guns with extensions/lances: These models come with lances or extensions, helping you reach further distances or heights without a ladder. They’re great for cleaning gutters, rooftops, or tall vehicles.
Trigger spray washer guns: These models feature a trigger mechanism that gives you control over the water flow. They’re user-friendly and ideal for precision cleaning.
Washer guns with adjustable nozzles: These washer guns allow you to adjust the spray pattern for different tasks. You can switch between a narrow, high-pressure jet for intense cleaning and a wide, low-pressure fan for rinsing or gentle washing.
Are pressure washer guns universal?
Pressure washer guns almost always work the same way, so they are usually interchangeable. While different brands of guns may look different and some may have more accessories, their basic functions are standardized. Some manufacturers will offer their own brand of gun to match their pressure washers. If you want 100% compatibility and to avoid using the wrong accessories, it is recommended that you choose the same brand of gun. Now, however, this is no longer necessary. Most consumer grade pressure washers have trigger guns that work the same way and they are essentially compatible with each other. Therefore, you can buy any brand of gun and they should all be compatible with your pressure washer.
However, it is best to pay attention to the following issues before buying so that you do not have compatibility issues.
- Water temperature: Many home models are designed for cold water, and while most professional-grade guns can withstand temperatures of at least 140°F, make sure the heat resistance of the gun is compatible with the temperature range of a hot water pressure washer. If your pressure washer uses hot water, you need to make sure your gun is rated for high temperatures (usually up to 250°F).
- PSI: PSI is a measurement of pressure. The gun must be rated at the same or higher PSI as the pressure washer to avoid the risk of leaks or breakage. While some of our models are designed for low-pressure applications, most of our models can handle pressures up to 5000 PSI.
- GPM: Similar to pressure, matching the GPM rating of your pressure washer gun to the output of your washer will help protect your gun and pressure washer system from damage by maintaining an even flow rate.
- Connections: Commercial-grade pressure washer guns typically have an inlet port size of 3/8″ FPT and trigger guns typically have an outlet port size of 1/4″ FPT. Most users don’t have to worry about this, but if your pressure washer is a consumer-grade model or the hose ends are M22 twist-offs, you need to be extra careful.
Features to consider when choosing a pressure washer gun
Features to consider when choosing a pressure washer gun
- Ergonomic design: A lightweight pressure washer gun with a curved handle and easy-to-reach trigger can reduce hand fatigue and stress. We recommend the BISON commercial pressure washer gun, which is one of the most comfortable spray guns on the market.
- Materials and durability: Choose a pressure washer gun that is made of high-quality materials, such as brass or stainless steel, to withstand abrasive cleaning conditions and have a long life.
- Adjustable spray pattern: Having the ability to switch between different spray patterns (e.g., wide, narrow, and fan-shaped) allows for flexibility in handling more varied cleaning tasks.
- Price: Choosing the best equipment is important, but BISON recommends investing in a durable, high-quality professional pressure washer. Cheaply made pressure washer guns are more likely to malfunction, which can cause company downtime, safety issues, and operational disruptions.
How to use a pressure washer gun
- Safety first: Always wear safety goggles, and sturdy footwear, and avoid loose clothing that could get caught in the washer. Make sure the area is clear of other people or pets before starting.
Caution! Avoid pointing gun at yourself or others; never aim it at electrical outlets or appliances. Follow the safety instructions and guidelines provided by the manufacturer. - Inspecting the pressure washer and gun for any damage: Inspect the pressure washer and a gun before each use for any signs of wear or damage, such as cracks, leaks, or damaged parts. Pay close attention to the hose, trigger, wand, and nozzle, as these components are involved in the pressure washing process.
- Connect the pressure washer gun: Attach the pressure washer gun to the hose. Ensure it’s securely fastened to prevent any leaks or disconnections during operation.
- Attach the correct nozzle: Depending on the job at hand, select and attach the appropriate nozzle to the end of the washer gun. Remember, different nozzles provide different spray patterns and pressure levels. For stubborn stains, a narrow nozzle with a concentrated spray pattern works best; for larger surface areas, a wide nozzle with a fan spray pattern works best.
- Turn on the water supply: Before starting the pressure washer, turn on the water supply to allow water to flow through the system. This helps prevent damage caused by running the washer dry.
- Start the pressure washer: Once everything is connected and the water is running, you can start your pressure washer according to its specific instructions.
- Operate the gun: Hold the gun with both hands and aim it at the area you want to clean, one on the trigger and the other supporting the gun. Squeeze the trigger to release the pressurized water. Always aim the spray away from people, animals, and windows. Keep your fingers away from the trigger when not actively spraying to prevent accidental release of water.
- Adjust pressure and spray pattern: Adjust the pressure and spray pattern as needed for different tasks. For instance, use lower pressures for delicate surfaces and higher pressures for tough grime.
- Shut down properly: Once you’ve finished cleaning, release the trigger, turn off the pressure washer, and disconnect the water supply. Allow any remaining water to drain from the system before storing the gun. If your pressure washer has a safety lock on the trigger, engage it to prevent accidental spraying during shutdown. Finally, rinse the gun, lance, and nozzles with clean water to remove any residual detergent or debris, And keep the equipment dry.
Pressure washer gun accessories
Nozzles: These come in various sizes and spray patterns, allowing you to adjust the pressure and angle of the water stream based on the job at hand. Some common nozzle types include 0-degree, 15-degree, 25-degree, 40-degree, and soap nozzles.
Extension wands/lances: These are ideal for reaching high or hard-to-reach places without the need for a ladder. They attach directly to your pressure washer gun and can extend several feet.
Hose adapters: These are used to connect or extend your pressure washer hoses. They come in various sizes to suit different hose diameters.
Soap dispensers/detergent bottles: These attach to your pressure washer gun or hose and allow you to apply detergent for deep cleaning tasks. Some models have adjustable dials to control the amount of soap dispensed.
Surface cleaners: These are large, round attachments that cover a larger area than a standard nozzle, making them great for cleaning large flat surfaces like driveways or decks.
Brush attachments: These can be used for scrubbing stubborn dirt or grime during pressure washing. They’re typically used for tasks such as car cleaning or window washing.
Quick connect kits: These allow for easy and quick switching between different nozzles or accessories without having to screw and unscrew each time.
Gutter cleaners: These are bent wand attachments that help you clean gutters without needing to climb a ladder.
Pressure washer gun maintenance
In the world of pressure washing, we understand that your equipment is the lifeblood of your operation. That’s why regular maintenance of your pressure washer gun is not just recommended—it’s essential. Proper upkeep not only extends the lifespan of your equipment but also ensures peak performance and safety. Here’s our guide to keeping your pressure washer guns in top-notch condition:
Regular inspections: Regularly check your pressure washer gun for any signs of wear or damage. Pay special attention to the hose connections, seals, and the trigger for any potential issues.
Clean after every use: Ensure you rinse the detergent off the gun and through the system after each use. This prevents any buildup that could clog your system and reduce efficiency.
Nozzle maintenance: Remove and clean the nozzles regularly to prevent any blockages. A small piece of debris can significantly reduce your pressure washer gun’s effectiveness.
Proper storage: Store your pressure washer gun in a clean, cool, and dry place to prevent rust and corrosion. Always disconnect from the pressure washer when not in use to relieve any residual pressure.
Lubrication: Lubricate moving parts such as the trigger mechanism and connections periodically to ensure smooth operation. Lubricate these parts every 3-4 uses or more often if you notice stiffness or resistance.
Winterize: If you’re in a region with freezing temperatures, make sure to protect your pressure washer gun from the cold as water left inside can freeze and cause damage. Consider using an air compressor to blow out any remaining water in the system. You can also use a special pump saver or non-toxic RV anti-freeze through the gun to further protect against freeze damage.
Remember, a well-maintained pressure washer gun is a powerful tool. And as a business owner, investing time in maintenance now can save you money on costly repairs or replacements down the line.
Your equipment is your partner in this business. Treat it with care, and it will serve you well in return. Happy pressure washing!
Troubleshooting pressure washer guns
- No pressure or low pressure: This could be due to a clogged nozzle. Turn off the system and check the nozzle for any debris. If it’s blocked, you can clean it with a small piece of wire or a needle. Also, check whether the water supply is sufficient and the hose isn’t kinked or leaking.
There can also be pressure issues with air in the system, you can try disconnecting the gun and letting the pressure washer run for a minute to clear out the trapped air. - Pressure washer loses pressure when the trigger is pulled: This could indicate an issue with the unloader valve, which is designed to divert water flow when the trigger isn’t engaged. You might need to adjust or replace this part.
- Cannot shut off pressure: If you cannot shut off the water from the trigger wand and there are no known issues with the unloader valve, there is likely an issue with the wand itself. The problem could be a stuck trigger due to dirt or debris. Clean the trigger area thoroughly, and if the problem persists, consider replacing the gun.
- Pressure washer pulsates (surges in pressure): There are two possible reasons why this may happen. The first possibility is that the pressure washer’s unloading valve is faulty, and the faulty valve needs to be replaced. The second possible reason is a water supply problem. Please check whether the water supply source has sufficient flow and pressure. Also, confirm whether there are any kinks in the hose or closed valves.
- Leaking gun: First check if there are loose fittings, try tightening all connections between the gun, hose, and pressure washer. Be careful not to overtighten. If this is not the problem, then the seal or O-ring is worn and causing the leak. Inspect these parts and replace them if necessary. Always make sure connections are tight and secure. The last and most unfortunate event is a crack in the gun body or joints which will require professional repair or replacement.
- Irregular spray pattern: This is often caused by a worn-out or incorrect nozzle. Check the condition of the nozzle and replace it if needed. Ensure you’re using the right nozzle for the job.
What should you know about upgrade pressure washer guns?
When considering upgrading your pressure washer’s lance, the most obvious reason is that the current lance is damaged. However, if you want better cleaning results, upgrading the lance can be a good option. More research and understanding is needed when choosing to ensure your choice is right for your pressure washer. Other factors worth considering include ergonomic design and durability. A good gun design should make it more comfortable for you to use. Also, if you use your pressure washer frequently, it is recommended that you choose a durable, heavy-duty gun. In addition, the PSI capacity and GPM flow rate of the cleaner need to be considered to ensure that the gun, spray bar and nozzle you choose will meet your needs. Finally, it is important to note that not all pressure washers require an upgraded gun. If your pressure washer is already capable of meeting your needs, then upgrading the gun may not be necessary.

FAQs about pressure washer gun
A pressure washer is an efficient device that uses water flow to clean surfaces. Water pressure is measured in pounds per square inch or lbs, and cleaning capacity can be measured in gallons per minute (GPM). PSI rating reflects the strength of the water flow and is important for understanding the overall power of a pressure washer. The overall power of a pressure washer can be calculated by multiplying PSI by GPM (PSI x GPM). In pressure washer guns, the highest PSI can be 3100 or higher. At Bison, we recommend a washer for light duty work for vehicles or outdoor furniture with a maximum PSI of 1899. medium duty is recommended for fences or patios with a maximum PSI between 1900-2799. Heavy duty jobs are recommended for driveways or stripping paint with a maximum PSI of 2800 and up. In addition, we offer commercial pressure washers with a maximum PSI of over 3100 for a variety of commercial needs.
There are advantages and disadvantages to both domestic and industrial pressure washer guns. Choose the right gun based on the use scenario and needs. Household guns are affordable and suitable for handling cleaning tasks in residential and domestic use, and usually do not require particularly powerful nozzles. Industrial guns, on the other hand, are usually designed to be more durable and suitable for greater water pressure and frequency of use.
The service life of a gun depends on maintenance and use. A well-maintained gun will last for years, while a poorly maintained gun will wear out quickly. Maximize the life of your gun by cleaning it regularly and following the manufacturer’s usage guidelines.
