How to Connect Pressure Washer Spray Gun to Garden Hose?

Pressure washers are a great way to clean driveways, sidewalks, and decks. But what do you do if you want to use your pressure washer to clean your car or boat? That’s where the garden hose comes in!

A pressure washer attachment for a garden hose can be described as a handy household item. You may utilize the many pressure levels to clean your car, water the lawn, maintain your driveway and walkway, wash your deck, and much more.

Pressure washer attachments are available with many types of nozzles. Know how you want to use the pressure washer attachment before purchasing so that you have the right type of nozzles for the job. Many pressure washer attachments come with a number of nozzles.

However, since you can adjust the pressure or temperature of the water at any time using a pump and wand, there are no restrictions.

A higher-pressure nozzle for example (which shoots an intense jet stream of water) is perfect for reaching high places or hard-to-reach crevices.

If you used this nozzle to irrigate your garden, for example, the plants would most likely be harmed because of the high water pressure. Similarly, you cannot clean your automobile or bathe your dogs with this nozzle.

A 25-degree nozzle, which produces a narrow fan of water, is ideal for cleaning wooden surfaces like fences and decks.
You may also utilize this nozzle to clean your house’s siding or the decking on your lawnmower. A wide nozzle, such as one that shoots out 65 degrees, is perfect for cleaning the car using detergents [1].

In this blog post, we will show you how to connect your pressure washer spray gun to a garden hose.

The Difference Between A Garden Hose And A Pressure Hose

The pressure of a typical garden hose ranges from 80-150 running PSI (pounds per square inch). This is adequate for most home applications, as the water pressure coming out of a classic household water source is usually around 80 PSI.

The Difference Between A Garden Hose And A Pressure Hose

Some of the best-related items from this category include hose extenders, heavy-duty garden hoses with burst resistance of 600PSI, and pressure washers.

A pressure washer, on the other hand, generates significantly higher water pressure. The pressure varies from 1000 to 6000 PSI, depending on the type of pressure washer. A hose that is specifically made for high PSI connections between your pressure washer and spray gun will be required [2].

You’ll undoubtedly discover that you can’t connect your garden hose to the output gasket of your pressure washer. It’s designed in this manner so that users will not inadvertently connect a low PSI hose to a pressure washer.

Additionally, unless you buy a used pressure washer, it will most likely come with a pressure washer-rated hose that matches the machine’s PSI output.

The pressure washer is also likely to include a quick-connect connection on the end of each hose, making it simpler to attach and remove them from your washer.

Different Fittings That Can Be Used On A Pressure Washer

There are three types of fittings that can be used on a pressure washer gun:

  • The first type is the screw-on fitting, which is the most common type of fitting. It is simply a matter of screwing the pressure washer gun onto the garden hose;
  • The second type is the quick-connect fitting, which has a spring-loaded sleeve that locks onto the garden hose. To release the pressure washer gun, you simply push the sleeve in and turn it counterclockwise;
  • The third type of fitting is the bayonet fitting, which consists of a collar that slides over the garden hose and locks into place with a set of teeth. To release the pressure washer gun, you pull on the ring at the end of the collar and twist it counterclockwise;

The most important thing to remember when choosing a fitting for your pressure washer gun is to make sure that it fits the hose that you have. If it does not fit, then it will not work properly and could cause damage to your pressure washer or hose.

Types Of Connectors

M22 Connection

The M22 connection is the most common type of pressure washer hose connector. It has a male and female end that screw together to form a tight seal.

M22 Connection

To connect an M22 pressure washer hose connector, simply screw the male end into the female end until it’s tight. You may need to use a wrench to get it started, but once it’s threaded in, you should be able to finish tightening it by hand [3].

If you’re having trouble getting the connector started, try lubricating the threads with soap or water. This will help it start more easily. Once you have the connector screwed on, give it a tug to make sure it’s secure before using your pressure washer.

3/8 Inch Connection

Most pressure washer hoses have a standard garden hose connection of 3/8 inches. These three-way taps are basically M22 connectors. They’re a fraction narrower than M22. 3/8 adaptors will not fit in M22 connections.

Male and female versions are available. As a result, only the opposite is linked. You can convert a female to a male connection using an adaptor if your hose and wand have the same type of connector.

If your pressure washer has this type of connection, you will need to purchase an adapter to connect the two. The size of the adapter will be determined by the size of your pressure washer’s outlet port.

To attach the adapter, first screw it onto the pressure washer’s outlet port. Next, take the garden hose and screw it onto the other end of the adapter. Once both hoses are securely attached, turn on your pressure washer and test the connection by pulling the trigger on the spray gun.

If you have any leaks, tighten all of the connections until they are snug. If you still have leaks, you may need to replace one or more of the seals on your pressure washer or garden hose. Be sure to check for damage before reusing either hose.

Quick Connect (QC)

Quick connect fittings make it easier to attach and remove hoses by converting screw connections to quick connect/release.

Female quick connect hose connections (also known as sockets) include an O-ring to prevent leaks. The end that connects to the other equipment is referred to as a plug.

Quick Connect (QC)

Most hoses today are QC connections out of the box, as they have been for years.

Quick connects have a male end that plugs into the female end, and they are held together by a latch or ring. To connect a quick connect, simply push the male end into the female end until it clicks into place. You can then pull on the quick connect to make sure it’s secure before using your pressure washer.


Most pressure washers will have a standard hose connection size of either ¾ inches or ⅝ inches. To connect the garden hose to the pressure washer, you will need to use an adapter. The most common type of adapter is the brass garden hose swivel adapter. This type of adapter has a male and female end that can be screwed onto the pressure washer and garden hose respectively.

Swivel fittings are used to connect two hoses together and allow them to rotate independently of each other.
This prevents the hoses from tangling or twisting while in use. Swivel fittings are most commonly found on pressure washer hoses, but they can also be used on other types of hoses as well.

To connect a swivel fitting, simply screw the male end into the female end until it’s tight. You may need to use a wrench to get it started, but once it’s threaded in, you should be able to finish tightening it by hand.

Once the swivel is connected, give it a tug to make sure it’s secure before using your pressure washer [4].

Hoses Diameter And Fittings Diameter

Any sort of fittings may be used on a hose with a certain diameter. The hose and fitting diameters are not the same. At the conclusion of a 1/4-inch diameter pipe, M22, 3/8-inch threaded, or quick-connect fittings can be installed.

The connector at one end of the hose should match the one on the other side of your wand. When it comes to purchasing a new hose for your pressure washer, you must double-check its finishes.

If you’re not careful, it could ruin the entire system.

When you have a pressure washer, the most important accessory is undoubtedly the hose. The hose is responsible for carrying water from the pump to the wand and nozzle. If there is a leak in the hose, it can cause major problems with your pressure washer. That’s why it’s important to know how to properly connect your pressure washer hose to your garden hose[5].

Connecting A Pressure Washer Gun To Garden Hose

If you’re looking for an easy way to clean your car or wash the driveway, then you’ll need a pressure washer. These devices use high-pressure water to power through dirt and grime and make short work of tough cleaning jobs.

Connecting A Pressure Washer Gun To Garden Hose

But before you can start using your pressure washer, you’ll need to know how to connect the pressure washer spray gun to a garden hose.

Steps To Connect A Pressure Washer Gun To Garden Hose

Measure The Gallons Per Minute (GPM) Of Your Water Supply

The connection type you choose between the pressure and your garden hose is determined by what you will use it for and how often you will use it. The first step is to figure out how quickly water flows through your tap. It’s possible to figure out how many gallons pass through your faucet each minute.

Because most pressure washers need a 3 gallon-per-minute water supply, your water source should be able to produce three to five gallons in a single minute.

To find out the GPM of your water supply, put a 3-gallon pail under your faucet and time how long it takes to fill it.

Repeat the process three times to get the average time it takes your water supply to fill a 3-gallon bucket. If filling a 3-gallon bucket takes less than 60 seconds, it may be used to provide water for a power washer.

A low GPM water supply can cause pressure washers to break. The average flow rate of a pressure washer is 2-3 GPM. Fill a 3-gallon bucket and time how long it takes to fill it to determine your flow rate.

If the water level in your pressure washer does not fill up within a minute, you may use that supply for it.
This step should not be overlooked since a lack of flow might cause the pressure washer to fail [6].

Connect A Splitter

If you only need to use your pressure washer occasionally, then connecting a splitter to your faucet is the way to go. This will allow you to keep using your faucet for other things while also having a spot to connect your pressure washer.

Connect A Splitter

To do this, find a Y-shaped connector that has one side for attaching to a faucet and two sides for attaching hoses. Once you have the splitter, screw it onto the end of your faucet. Then, take one end of your garden hose and screw it into one side of the splitter.

Connect The Water Inlet With A Garden Hose

The next step is to connect the garden hose to the water inlet on your pressure washer. Make sure the connection is tight and free of leaks. After that, connect the other end of your garden hose to your water source.

Examine the drains for any leaks and double-check if everything is connected. If any leaks are discovered at connecting locations, you must find a fitting to stop the flow.

Attach The Wand Of The Pressure Washer To Your Garden Sprayer

The pressure washer hose must then be connected to the wand or spray gun. After that, connect the opposite end of the pressure hose to your power washer’s water supply. This is because a longer hose will result in a lower PSI while still delivering the needed flow rate to power wash appropriately.

The Power Washer Attachment For Garden Hose Tips:

  • To avoid stripped threads, always use a washer between the hose and the adapter;
  • Do not overtighten. Hand tighten only;
  • If your pressure washer has an adjustable spray nozzle, set it to low pressure before connecting to the garden hose;
  • Connecting the pressure washer attachment to the garden hose is quick and easy;

Attach The Wand Of The Pressure Washer To Your Garden SprayerNow you are ready to use your pressure washer attachment! Simply point and spray away dirt, grime, and gunk from any outdoor surface. From driveways and sidewalks to decks and patios, power washing with a garden hose has never been easier.


Can you use a pressure washer gun with a hose?

Yes, you can use a pressure washer gun with a hose. You will need to purchase a pressure washer gun that has the proper fittings to connect to your garden hose.

Make sure that the pressure washer gun is rated for the PSI of your garden hose. Most pressure washer guns have a maximum PSI rating of 400.

You may also need to purchase an adapter to connect the pressure washer gun to the garden hose. Adapters can be found at most hardware stores. Follow the instructions that come with the adapter to properly connect it to the garden hose and pressure washer gun.

Once you have everything connected, turn on the water at the spigot and then squeeze the trigger on the pressure washer gun to release the water. Start by holding the pressure washer gun about a foot away from the surface you are cleaning and then move it closer as needed.

If you are using a pressure washer for the first time, be sure to read the safety instructions that come with the machine. Do not point the pressure washer gun at anyone and always keep your fingers away from the trigger when not in use.

Can you put a pressure washer nozzle on a garden hose?

Your garden hose will clean your automobiles and mold from house siding when it has greater water pressure. Although adding a high-pressure nozzle to the garden hose can enhance its water pressure, it will not create the substantial water pressure created by a power washer.

Do you need a special high-pressure hose for a pressure washer?

No, you do not need a special hose for a pressure washer. You can use a standard garden hose.

However, there are a few things to keep in mind:

  • The first is that the diameter of the hose should be at least three-quarters of an inch. This will ensure that enough water flows through the hose to power the washer;
  • Second, make sure that the end of the hose is equipped with a high-pressure nozzle. This will help to create a tight seal when you attach it to the pressure washer gun;
  • Finally, be sure to check the maximum operating pressure of your garden hose before using it with a pressure washer. Most hoses have a maximum operating pressure of 150 PSI, which is more than enough for most pressure washers;

What size are pressure washer fittings?

There are just three kinds of connections on gas units, and they’re all the same: M22, 3/8-inch threaded, and Quick Connects (QC). The only exception is for the gun and lance [7].

What type of fittings do pressure washers have?

Most pressure washers will have either quick-connect or threaded fittings:

  • Quick-connect fittings are the most common and are found on almost all residential models;
  • Threaded fittings are more common on commercial grade pressure washers;

To connect your garden hose to a pressure washer with quick-connect fittings, simply insert the garden hose into the inlet until it clicks into place. To disconnect, press the release button and pull the hose out.

What type of fittings do pressure washers have?

For pressure washers with threaded fittings, screw the garden hose onto the inlet until it is tight. Unscrewing it in the opposite direction will loosen and release it. Be careful not to over-tighten as this can damage the threads.

How much PSI is a garden hose nozzle?

Hoses for smaller purposes, such as watering the lawn or washing your car, have a burst pressure of up to 200 PSI. High-quality hoses can reach a burst pressure of up to 400 PSI, and sometimes even more [8].

Can you use a collapsible/expandable hose with a power washer?

Yes, you can use an expandable hose with a pressure washer if your expandable hose is connected between your house or garden faucet and the water intake of your pressure washer. Never use an expansion hose between the water outlet of your pressure washer and the spray gun [9].

How long of a hose can you use with a pressure washer?

You can use a pressure washer with any length of hose, but the longer the hose, the lower the water pressure. If you need to extend your reach, consider using an extension wand.

Are all pressure washer connectors the same?

No, not all pressure washer connectors are the same. The size and type of connector will depend on the model of pressure washer you have. Some pressure washers have quick-connect fittings that make it easy to connect and disconnect the hose from the spray gun. Others may require that you use a wrench to tighten or loosen the connection.

If you’re not sure what type of connector you need, consult your pressure washer’s manual or contact the manufacturer. You can also bring your old hose and spray gun to a hardware store or home improvement center and ask an associate for help finding a replacement.

How do you connect a hose to a jet wash?

There are two ways to connect a hose to a pressure washer:

  • The first is by using the quick-connect fittings that are located on the back of the pressure washer;
  • The second way is by using threaded fittings that screw into the back of the pressure washer;

If you have quick-connect fittings, simply push the hose onto the fitting until it clicks into place. If you’re using threaded fittings, screw the hose onto the fitting until it’s tight.

Once your hose is connected, turn on your water supply and then start your pressure washer. Make sure to hold onto the trigger while you’re doing this so that water doesn’t spray out everywhere!

How do I pressure wash without a pressure washer?

If you don’t have a pressure washer, you can still clean your patio or deck by using a garden hose and a little elbow grease:

  • First, sweep the area to remove any loose dirt or debris;
  • Next, mix a solution of one part water to one part vinegar in a bucket;
  • Then, wet your surface with the garden hose and scrub it with a brush dipped in the vinegar solution. Rinse the area with clean water from the hose and let it air dry. Your patio or deck will be sparkling clean in no time;

Do quick connect fittings swivel?

Yes, quick connect fittings swivel. This is important because it allows you to change the direction of the spray without having to remove the fitting.

How can I use a pressure washer without an outside tap?

If you don’t have an outside tap, you can use a pressure washer with a garden hose adapter. This will allow you to connect the pressure washer to a standard garden hose [10].
