The most common garden hose for pressure washers, also known as the standard garden hose, is 3/4 inches in diameter.

But you can consider buying a larger size, such as a one-inch or 1 1/4 inches garden hose, depending on your pressure washer.

If you are confused in determining the size of the garden hose for your pressure washer, just remember these tips:

  • A 2700 psi pressure washer will work well with a 3/4 hose.
  • Also, for 2700 PSI to 3600 PSI, 1-inch hoses will be your best bet.
  • The biggest diameter hose is 1 1/4 inches, permitting the most efficient water flow while minimizing wasted energy.

3/4-Inch Garden Hose

You can use 3/4-Inch garden hoses for various tasks, such as cleaning vehicles, watering plants, filling baby pools, etc. These hoses are standard ones that are affordable and easy to find.

  • Hose diameter: 3/4 inches.
  • Hose length: Range from 25 to 100 feet.

1-Inch Garden Hose

This garden hose can withstand up to 80 PSI, meaning it has more pressure than the standard 3/4 inch hose.

Greater pressure means you need an increased water flow. That is why you need a larger hose diameter.

  • Hose diameter: 1 inch.
  • Hose length: Range from 25 to 100 feet.

1 1/4 Inches Garden Hose

It is the largest size for a garden hose that you can find. This hose size allows for a significantly stronger water flow than 1-inch or 3/4-inch hoses.

This hose works well in completely saturating a large area with water to get rid of dirt rather than just spraying it around.

Because of its stronger water flow, some homeowners prefer this size to anything else. However, it is harder to find than a standard garden hose.

  • Hose diameter: 1 1/4 inches.
  • Hose length: unknown.

Things To Consider While Purchasing Garden Hoses

Things to consider when buying garden hoses

Diameter

Let's start by checking out the PSI level of your pressure washer before purchasing a hose.

  • If your machine has a pressure of 2700 PSI, you should choose a 3/4-inch hose.
  • For 2700 to 3600 PSI, 1-inch hoses will work well.
  • For more than 3600 PSI and up to 5000 PSI, you will be alright with a 1 1/4 inches diameter garden hose.

Length 

Determining the size of the hose is pretty simple.

If you want to cover a broad area, you'll need a lengthy hose, while a shorter length hose is ideal for a small and tight space.

With a longer hose, you may face issues such as less water pressure, stepping on your hose, and being heavy when carrying around.

Hose Material

The material of the garden hose is also an essential factor to consider as it dictates the durability, flexibility, and price of the hose. Hose material comes in three types, including:

  • Polyurethane hose: This type is the most expensive for many good reasons. It delivers the best of anything, including durability, flexibility, weight, etc.
  • Rubber or synthetic rubber hose: It is an excellent garden hose. A 50-ft rubber hose typically costs approximately $50 or more.
  • Plastic hose: This kind works well for light and medium-duty electric pressure cleaners. It is the cheapest hose but still flexible enough to be wound into a reel.

Yet, you will probably want more flex. The plastic hose is commonly  made from plastic PVC

Connection Type

No matter what kind of connection your pressure washer and pressure wand/ gun have or what connection kind comes with your chosen hose, there is always a proper adapter to make them work.

Here are connections available out there:

  • Female & Male Quick-connect: It typically comes with your pressure washer. If you want more, you can order it when buying the hose.
  • Female & Male M22 threaded: In most cases, extension/replacement hoses are M22 female on both ends. So your pressure gun/wand would need to be an M22 male.

Temperature

Every garden hose has its temperature range in which it will function properly.

If you want to use a hot water pressure washer, you must ensure your chosen hose can handle the hot water. If not, it might weaken over time, leading to rupture.
