how much water does a pressure washer use

When it comes to power washing your home, garden and outdoor areas, the question of how much water does a pressure washer use is one that’s often asked. With summer fast approaching and with more time spent outdoors than ever before this year, understanding the amount of water used by a pressure washer can help you plan ahead for all those big cleaning jobs! In this blog post, we’ll discuss the basics of pressure washers when it comes to water usage as well as looking at ways in which you can reduce your own personal consumption. We’ll also compare traditional hoses versus modern-day electric or gas powered machines – so stick around until the end if you want to find out which uses more water!

Pressure Washer Water Usage: The Basics

Pressure washers are a great way to quickly and efficiently clean outdoor surfaces, such as patios, driveways, and decks. However, it’s important to understand how much water pressure washers use so you can make sure your cleaning is done in an environmentally friendly manner.

The amount of water used by a pressure washer depends on the type of machine you have and the settings that you choose. Generally speaking, electric pressure washers will use less water than gas-powered models due to their lower power output. On average, electric pressure washers will consume around 2 gallons per minute (GPM) while gas-powered machines can range from 4 GPM up to 8 GPM or more depending on the model.

In addition to the type of machine you own, there are several other factors that can affect how much water your pressure washer uses:

The size of the nozzle – A larger nozzle opening allows for more water flow which means higher consumption rates; conversely, smaller nozzles reduce the flow rate and conserve more water.

The PSI setting – The higher the PSI setting on your machine, the greater amount of force behind each spray which requires more water usage; using a lower PSI setting conserves more H2O during operation.

The length of time running – If you leave your machine running for longer periods without interruption then it will obviously consume more water than if it runs only briefly at a time with frequent breaks in between sessions.

Overall, understanding how much water your specific model consumes is key when deciding whether or not this method is right for cleaning jobs around your home or garden area – especially if local regulations limit total daily consumption amounts.

Pressure washer water usage can vary depending on the model, but understanding the basics is key to ensuring efficient and effective use. Now let’s look at how you can reduce pressure washer water usage.

Key Takeaway: Pressure washers can be an efficient way to clean outdoor surfaces, but it’s important to understand how much water they use. Factors such as machine type, nozzle size, PSI setting and running time all affect the amount of water consumed.

How to Reduce Pressure Washer Water Usage

If you’re not careful, they can use an excessive amount of water. Here are some tips for reducing the amount of water your pressure washer uses:

1. Use Low-Pressure Settings: Pressure washers come with adjustable settings that allow you to control the strength of the spray. When possible, use lower-pressure settings as this will reduce the amount of water used by your pressure washer without sacrificing cleaning power.

2. Avoid Over-Spraying: It’s easy to get carried away when using a pressure washer, but it’s important to avoid over-spraying areas that don’t need to be cleaned or rinsed off with high-pressure jets of water. This will help conserve both time and water while still getting good results from your pressure washing job.

3. Choose Eco Mode: Many modern pressure washers have an “Eco Mode” setting which reduces the flow rate and helps save on water usage without compromising performance levels too much – perfect for those who want their cleaning jobs done quickly but also want to conserve resources at the same time.

4. Reuse Water Where Possible: If you’re working on multiple projects in one day, try reusing any excess dirty or soapy water where possible rather than running fresh batches each time – this can help cut down on overall consumption significantly.

While there are many benefits associated with using a pressure washer, it is important to consider alternatives such as hand scrubbing or steam cleaning where appropriate. These methods may take longer but could end up saving more in terms of both energy and resource costs over time.

By making sure you only use the pressure washer when necessary, and using a low-pressure setting for delicate surfaces, you can significantly reduce water usage. Now let’s look at how a pressure washer compares to a hose in terms of water consumption.

Key Takeaway: Pressure washers can be an effective and efficient way to clean outdoor surfaces, but it’s important to use lower-pressure settings, avoid over-spraying, choose eco mode when available and reuse water where possible in order to conserve both time and resources.

Pressure Washers vs Hoses: Which Uses More Water?

When it comes to cleaning outdoor surfaces, pressure washers and hoses are two of the most popular tools. But which one uses more water? Let’s take a look at how each works and compare their water usage.

Pressure Washers: Pressure washers use an electric motor or gas engine to power a pump that pressurises the water from your garden hose up to 3,000 PSI (pounds per square inch). This high-pressure stream is used for powerful cleaning jobs like removing dirt and grime from driveways, decks, siding, etc. The amount of water used by a pressure washer depends on its GPM (gallons per minute) rating; higher GPM ratings mean more water is being sprayed out in less time.

Hoses: Hoses use gravity to pull down on the flow of water coming out of them. This means they don’t require any additional energy source like an electric motor or gas engine – just turn on the tap. A standard garden hose typically has a 5/8-inch diameter opening with a maximum flow rate around 10 gallons per minute when connected directly to your home’s main line. While this may seem like quite a bit compared to other household appliances, it’s still much lower than what you’d get with even low-end pressure washers.

So which uses more water? Generally speaking, pressure washers will use more because they can spray out significantly larger amounts of liquid in shorter periods of time than hoses can manage through gravity alone. However, if you’re using either tool for small tasks such as watering plants or washing cars then there won’t be much difference between them in terms of total volume consumed over time – both will do the job just fine without wasting too much precious H2O.

Key Takeaway: Pressure washers use more water than hoses because they can spray out significantly larger amounts of liquid in less time. However, for small tasks like watering plants or washing cars, both tools are equally efficient and won’t waste much water.


In conclusion, it’s important to understand how much water a pressure washer uses and the various ways you can reduce your usage. Pressure washers are an effective way of cleaning outdoor surfaces but they do use more water than a hose. However, if used correctly with appropriate settings and nozzle attachments, you can still achieve great results while using less water than expected. So next time you’re wondering “how much water does a pressure washer use?” remember that there are many factors to consider before making your decision!
