Turn Garden Hose Into Pressure Washer: 3 Easy Steps

Gardeners know that a pressure washer in their yards is indispensable. Time and again, outdoor hard surfaces such as patios and wooden decks require spray cleaning.

The approach is much faster and easier than the traditional soap and water brushing that takes forever.

Are you wondering what the cost of purchasing a pressure washer is? Before we get to that, lets do some quick math.

Typically, hard surfaces require cleaning once in a while. Should you buy a pressure washer, you will only use it occasionally, but most often, it will be gathering dust in your yard.

Similarly, renting one may not be ideal since the cost adds up with every rental.

Okay, so what options are you left with—nothing better than turning your garden hose into a pressure washer. Let’s explain this further in the steps below.

Materials Required

  • Water hose. 
  • High-pressure spray nozzle. 

Steps To Turning Your Garden Hose Into A Pressure Washer

Before we talk about the steps, you need to know the pros and cons of this method.

First off, you want to ensure your converted garden hose generates enough water pressure to be of any use. For instance, the removal of molds from the exterior surfaces of the house requires some serious force.

A typical pressure washer serves this purpose well since it contains a pump that produces at least 500 pounds per square inch of water pressure.

A high water pressure nozzle can turn your water hose into a pressure washer. However, it still won’t be anywhere near the capacity of a pressure washer.

The best approach is to attach your water hose to a fire-fighting nozzle with a 250 psi rating. Let’s get down to the setup process. 

Step 1: Inspect Existing Water Hose

The water hose to use must meet certain conditions to function optimally. Check if this is true by inspecting the end of the hose.

Its design should be able to screw onto a faucet. Also, check the rubber washer for any cracks. Should you notice any, change it to a new one.

A cracked rubber washer reduces the water pressure. You also want to check the entire length of your hose for any damages to ensure your high-pressure nozzle works effectively.

Using a very long pipe also reduces the pressure significantly. Work with the shortest possible length you can for cleaning effectively. 

Step 2: Attach The Fireman-Type Nozzle

For the best results, you want to attach the fireman type nozzle. We recommend purchasing the 250 psi variant. It’s affordable and readily available in retail stores. 

You can attach a nozzle to a hose in two ways: 

  • Screw tap with a 3/4″ plastic fitting. Push-fit the hose connector onto this fitting. 
  • Fit hose with a brass female ¾” BSP type threaded connector that comes with a bayonet connection that pushes into the hose. 

Once attached, you are ready to make use of the makeshift pressure washer. Use safety glasses when using the hose to avoid hurting your eyes.

Step 3: Adjust The Nozzle 

High-pressure nozzles are usually equipped with settings that can adjust the pace and shape of water coming out.

You can alter these settings depending on the surfaces you intend to clean. For example, if you want to clear up grime from concrete surfaces, you can adjust the nozzle to a pinpoint shape.

For delicate surfaces like windows, make the spray water wide to avoid damages. The other thing is to avoid wasting water by starting slowly and gradually increasing the pressure.

Other Ways To Increase Water Pressure In A Garden Hose 


  • Check the connection between the garden hose and the outdoor faucet. Water should not be dripping at this junction.
  • Use a water hose with a large diameter. The medium hose diameter is 5/16″.
  • Do not confuse flow rate with pressure. A small diameter doesn’t increase water pressure, but shorter pipes do.
  • Low water pressure could also be caused by clogging, leakages, or corrosion in the spigot valve.
  • Avoid twisted and kinked sections on the water hose.

Wrap Up 

If you can afford a pressure washer, you don’t have much to think about.  However, a pressure power washer is heavy and bulky and also consumes tons of electricity. Besides, you will have to grapple with loud noise.

On the contrary, using an improvised water hose for the same purpose is more convenient and pocket-friendly.
