Can I Turn My Hose Into a Pressure Washer? What the Pros Say


It doesn’t make sense to buy an expensive pressure washer for occasional household cleaning. A much easier and cheaper solution is to turn your hose into a pressure washer. There are multiple options to do this.

Can I Turn My Hose Into a Pressure Washer?

In general, you can turn your hose into a sort of pressure washer using a hose extension. If the pressure of your main water supply is good enough, it will give a significant increase in output pressure. You can expect a pressure of up to 250 PSI from the 30 to 40 PSI water supply. But not nearly as powerful as a pressure washer that can deliver 1500 PSI and up. Hose extensions are fine for many light-duty cleaning jobs, like cleaning your car, sidings, patios, windows, or the pavement.

This article will show you how to convert your hose into a sort of pressure washer. I will look at the different options and tips to increase the hose water pressure.

Convert your hose into a pressure washer

These are the steps to convert your hose into a pressure washer:

● Step 1: Inspect the hose

The hose adapters that convert the hose into a pressure washer don’t produce as much pressure as an electric or even more powerful gas-powered pressure washer. Pressure washers have a built-in pump that delivers 500 PSI or more. Hose adapters, like a firefighter-type nozzle, produce pressure up to 250 PSI. This pressure is enough to blow out old or damaged hoses, fittings, and connections. The first step in converting a hose into a pressure washer is to inspect the fittings and washers. And the full length of your hose for cracks or damage.

– Check for leaks in the hose:

The higher the water pressure, the hight the hose extension output pressure. A leaking hose is one of the most common problems that can decrease water pressure. Lay the hose flat on the ground and move along the hose to check for points where water is leaking. The leaks can be tiny, so you must inspect them carefully. Use a rubber patching kit to repair them or completely remove the damaged part.

– Check for the connection of hose with the spigot and nozzle:

It’s important to look for any leaks at the points where the nozzle is connected to the hose and where the hose is connected with the spigot. The water pressure from a hose drops due to improper connections at those ends. Remove the nozzle and spigot connections and look for any blockages that may prevent the water from flowing. Make sure to check the connections across the splitters as well, if you are using any. Tighten all the connections to fix the problem with the increased water pressure.

– Look for the twists in the hose:

Sometimes the water pressure drops suddenly due to the twists in the hose. Always try to have the hose as straight as possible. If you have to bent the hose, try to make them as wide as possible, to have the lowest water resistance.

– Clean the inside of the hose:

If there are no leaks in the hose or connections, we need to check the hose itself. The pressure will be decreased when there is dirt inside the hose. To clean it, submerge the hose in a bucket filled with water and ¼ cup bleach solution. Let the hose sit in the bucket for 8 hours. Then, place the hose in plain water for an hour and spray it to get rid of any leftover dirt.

● Step 2: Install the high-pressure nozzle

High-pressure nozzles are readily available at hardware stores or online. These nozzles can be installed easily on the hose without any specialized tools. Here are different types of nozzles that can be used to convert a hose into a pressure washer.

– Turbo-Jet Power Washer:

A turbo-jet power washer is an excellent attachment that can convert any hose into a pressure washer. It has a built-in pressure chamber. It converts normal water flow into a powerful jet stream that helps you to remove dirt, grime, and mold. It can be used to clean wood, aluminum, concrete, bricks, vinyl sidings, and many other surfaces.

– Little Big Shot Super Nozzle:

This is one of the better high-pressure nozzles because of its small size. It produces 40% more pressure with 40% less water usage.

– Firefighter-style nozzles:

The firefighter-style nozzles are best for cleaning purposes. They produce up to 250 PSI water pressure.

– Wand-style nozzles:

Wand-style nozzles effectively increase the pressure of the water coming through the hose. They are a good choice for cleaning upper story windows, sidings, patios, and outdoor furniture.

– Squeeze-handle nozzles:

These nozzles produce water pressure up to 150 PSI. These nozzles can be used to clean dirt and mold build-up.

● Step 3: Keep the length of the hose short

To achieve the highest possible water pressure, keep the length of the hose short. The longer the hose, the more resistance for the water. This reduces the PSI rating. Always make sure that you use the shortest hose possible for your job, with the least amount of bends or twists.

● Step 4: Attach and adjust the nozzle

Install the appropriate high-powered nozzle to the hose. Some of these nozzles come with a long, thin tube and concentrate the water to increase the pressure. For cleaning different surfaces, you can adjust the nozzle. These adjustments include pressure and the shape of the spray.

Find the perfect pressure by opening the water flow lever slowly. To clean surfaces like concrete, adjust the nozzle spray to a pinpoint or compact fan shape. To prevent delicate surfaces, use a wider opening.

Can I Convert My Hose Into a Pressure Washer Using a Water Pump?

Water pressure from a hose can be increased by installing a water pump. This method is particularly suitable when you have a low-pressure water supply. A water pump connects to an outlet, and a hose is attached to the pump to get a stronger stream.

If you have low water pressure, installing a water pump in your main water supply system can be worthwhile. There are many types of pumps available in the market used for different purposes. To increase the pressure for outdoor use, a regular pump will be fine. 

Such pumps significantly increase pressure and allow you to achieve adequate pressure for cleaning outdoor areas and surfaces. A water pump comes with a water pressure regulator that allows you to control the pressure according to your choice.

How to Increase Pressure in the Hose Before Converting It Into a Pressure Washer?

Insufficient hose extension pressure is often due to low water supply pressure. Low water pressure from the hose can be due to a worn-out or damaged hose, an inappropriate nozzle, or a low water supply pressure. Before converting a hose into a pressure washer, try to increase the water pressure. This can be done by removing any blockages in the hose or faucet, adjusting the main valve or the water pressure regulator.

The pressure of the water supply can be measured with a pressure gauge. You can place the gauge near the main valve where the water enters your house. If the gauge shows a reading of less than 20 to 30 PSI, your water pressure is low. The result of using a hose extension will be less effective.

The higher the water pressure, the higher the hose extension output pressure will be. Following are some tips that can help you achieve the high water pressure possible in your situation:

● Low Water Pressure: Check the Outdoor Tap:

Low water pressure can be due to a faulty outdoor tap. Slight blockages in the pipes or the tap itself can decrease the water pressure significantly. The minerals in the water can form build-up or clogs in the tap, which hinders the water flow. If you live in such an area, try to clean the pipes and tap using a suitable cleaner.

● Low Water Pressure: Check the Hose:

The problem with the outdoor hose is somewhat similar to the tap problem. If your outdoor tap is working correctly and there is no build-up or clogs, the problem might be located at your hose. An entangled, cracked, or leaking hose can reduce the pressure. Water may not be able to reach the end of the hose effectively. Repairing the leaking or worn-out parts in the hose or installing a new hose can fix this problem. 
If your hose is not damaged or is new, the type of attachment can lower than expected output pressure. This problem can be solved just by replacing the old attachment with a good quality high-pressure attachment. Hence, from the above discussion, it’s concluded that you must always check your outdoor hose first if you are experiencing a low water pressure problem.

● Low water pressure due to high demand for water:

The cause of low water pressure may not always be due to the outdoor water supply. The demand for water during different times of the day affects the water pressure in your house. Generally, the water demand is very high in the morning and the evening. Or when the washing machine or dishwasher is running. Remember that this not only applies to your house but the whole neighborhood. It’s recommended to check the water pressure during different times and see whether the low pressure is due to high water demand. Using water outside peak times may affect the water pressure.

● Low Water Pressure: Check the Main Valve:

People often make the common mistake of not opening the main valve fully, reducing the water pressure. To solve this problem, you need to locate your house’s main water supply valve and ensure that it’s not damaged and is fully open.

● Low Water Pressure: Check the Pressure Regulator:

Low water pressure can be due to poor water pressure regulator adjustment, also known as the pressure-reducing valve. The water pressure regulator is often located along with your main stopcock valve. Measure the pressure with a pressure gauge nearest to the water regulator and see if the valve can be adjusted to increase the pressure. Generally, a PSI rating between 40 to 60 is considered excellent. Anything below 30 PSI means that the pressure of your water supply is low.
