Useful Guide: How Much Water Does a Pressure Washer Use?

Pressure washing is a great way to clean your home. It allows you to clean dirt and grime from hard-to-reach areas of your house. However, you will also need to know how much water is used by a pressure washer.

You will need to know this to know if using a pressure washer indoors is a good idea. If you don’t know then this blog is for you.

We’ll look at the different things that affect how much water does a pressure washer use and then give a brief overview of the typical water usage for these machines.

PSI and GPM: What do they Mean?

Before knowing about how much water the pressure washer uses you must learn about PSI and GPM.

A pressure washer’s power and water usage are determined by two factors. PSI is the first (Pounds per Square Inch).

The PSI indicates how much force is ejected from the nozzle. In general, a greater PSI indicates more force and cleaning power.

GPM is the second metric (Gallons Per Minute). In essence, it determines how much water the pressure washer consumes and uses. One thing to keep in mind is that GPM and PSI go hand in hand.

Most people believe that a pressure washer’s power is only determined by its PSI, however, this is not the case. To determine the power of your pressure washer, multiply the PSI by the GPM.

For Example if;

Pressure Washer 1: Has a total of 7,500 cleaning units and produces 3,000 PSI and 2.5 GPM.

Pressure Washer 2: Produces 2,500 PSI at 4 GPM and has a total cleaning capacity of 10,000 cleaning units.

Most people would choose Pressure Washer 1 just because it has a higher PSI rating. However, they are unaware that Pressure Washer 2 consumes more water per minute (GPM). It produces a higher cleaning unit even at a reduced PSI.

How Much Water is Used by a Pressure Washer?

The pressure washer’s GPM will vary depending on the brand, manufacturer, and model. Not all high-pressure washers are created equal.

There are different types of high-pressure washers that serve a variety of needs and can be used in many different applications.

The average good quality home repair high-pressure washer will ease the pressure in jobs around your home or business, reaching pressures upwards of 2,000 PSI at a flow rate of 1.8 GPM.

You’ll also find that the internal components are constructed out of sturdy materials and can handle countless hours of daily use over extended periods.

Many pressure washers come with automatic shut-off valves which means you won’t have to use up so much water each time you want to clean your car or wash your driveway.

This is great for the environment because most people tend to hoses until they drain completely, wasting up to 70 gallons of water per 10-15 minutes depending on how hard the water flows through the hose and your pressure washer nozzle.

Can a Pressure Washer Consume more than a Garden Hose?

Many people believe that because a garden hose does not shoot as much water at such a high pressure, it will use less water.

In actuality, the situation is the polar opposite. Because of the lower pressure, using a garden hose will result in increased water usage per minute.

While some pressure washers may use as little as 2 gallons per minute, a garden hose may consume roughly 20 gallons.

A garden hose, on the other hand, will be less effective at cleaning something on a deeper level. As a result, you may be able to utilize the hose for longer periods and consume even more water.

If you want to preserve water and make sure your sidewalk is spotless, a pressure washer is a better option than a garden hose.

How to use Pressure Washer?

A pressure washer is a powerful tool! It can do a lot of damage if it’s not used correctly, and when used incorrectly means that water usage is wasted.

We know sometimes cleaning things becomes to be a tiresome task, but don’t get tired because we have some tips that will help you keep your work clean while saving time as well.

Proper Assemble your washer

Once you’ve received your item, you should check that you have all the attachments against your receipt of purchase.

You should also check for any items that were damaged in transit or incorrect. Make sure to take a look through the guidebook to see how you assemble this particular tool. Look for whether or not the power cord is still intact and functional.

Using a Quality Nozzle

Pressure washers can come with different nozzles for cleaning various areas. People tend to make the mistake of using one kind of nozzle for various things, materials, and surfaces – but that only makes cleaning less effective.

There are different kinds of nozzle attachments, including a 0-degree one, which is used for cleaning things at close range and around corners, a 15-degree one for medium pressure, a 25-degree one for sharp and more direct spray, a 40-degree one for lower pressure, and a 65-degree one to help penetrate stucco.

Remember that Use only Hot Water

Cleaning various surfaces with a hot water pressure washer is more effective than cleaning with cold water.

Hot water is preferable since it aids in the removal of dirt more effectively. It also cuts down on cleaning time and the amount of cleaning solution needed.

You will use less water as a result. If at all possible, the water utilized should be between 160- and 210-degrees Fahrenheit.

If you simply require this machine for small domestic cleaning tasks, a lightweight hot water pressure unit that you will use less than 5 hours a week would suffice.

The best pressure cleaners can reduce a faucet’s flow to about 5 gallons per minute.
This is the average performance of a 4000 PSI cleaner, even though their price puts them out of reach for most people.

Power washers aren’t the friendliest thing in the world. In fact, they have a way of making everything around them look wonderfully clean – except for that water it emits when doing its job.
