What Size Garden Hose For Pressure Washer?

What Size Garden Hose For Pressure WasherThe pressure washer enhances the power of a common garden tap by increasing the pressure several times and can be used to clean all types of surfaces easily. The pressure washer pressure can range from 1000 psi to about 4000 psi, which is a lot of pressure. Another important thing in the pressure washer is the flow rate measured in GPM, and it is the major contributor to the cleaning of the surface by the pressure washer. The pressure is a threshold quantity, and you would not get the best cleaning effect by increasing the pressure, but it can damage the surfaces. However, the GPM directly impacts cleaning capacity, and the GPM is related to the capacity of the garden hose supplying the water to the pressure washer.

In this article, we are going to discuss the qualities, specifications, and size of the garden hose that you can use with the pressure washer.

What Size Garden Hose For A Pressure Washer?

There are two types of garden hose used in the pressure washer, the first is the garden hose that connects the inlet of the pressure washer with the garden tap, and the second is the one that connects the outlet pressure with the spray gun. The second garden hose is also known as a high-pressure or simple pressure hose.

The Low-Pressure Hose

The low-pressure hose is generally easier to find and is commonly used for various purposes. Depending on the area where you live, the garden hose must be able to withstand a specific range of temperature without degrading or losing its integrity. In the United States, the garden hose comes in different diameters with 1/2″, 5/8″, 3/4″, 1″, one ¼” etc. you should select the garden hose based on the GPM of your pressure washer. The more comprehensive the hose, the more water it can handle in a minute. It is better to go with the 1 inch or 1 ¼” hose if you are using a high GPM pressure washer.

The low-pressure garden hoses are available in 25 feet to 100 feet in size, and you can choose any of them based on your preferences. The factors need to be considered with the recommended temperature and pressure range. Most garden hoses are rated for less than 100 psi, but if you want them for a high-power pressure washer, you would need more than that. Another important thing is the temperature; the garden hose must be able to handle the surrounding temperature. They are made from plastic or rubber that can lose its integrity under too much heat. The garden hose that you are selecting must be able to handle the temperature.

Your garden should also have the ability to easily connect with a regular connector, so there is no need for particular components.

High-Pressure Hose

The high-pressure hose is the most crucial part of the hose, and they generally come with the pressure washer. If you need to buy a garden hose to connect the pressure washer output with the spray gun, you would need to consider some factors. The first is the pressure that it is going to handle. Most pressure washers are under the range of 2000 psi, but it is better to choose the garden hose that can handle 3000 psi because the instant pressure built up can cause the rupture. There are also some other factors, such as size, the diameter of the high-pressure garden hose does not matter much because, in the end, the water will come out of the nozzle. The length should not be more than what’s needed, and use the long high-pressure hose if only required.

The high-pressure hose must also be able to handle the soap and detergent if they are mixed inside the pressure washer. This can create corrosion, and it must be able to counter that. If the pressure washer is hot water enabled, then obviously, the temperature resistance of the garden hose at the high-pressure end should also be high.


Thus by reading this article, you will get an idea about the appropriate size of garden hose and the importance of the correct size for getting the maximum results.
