Best Pressure Washer Pump Buying Guide

A pressure washer is truly the best way to deep clean a large and thoroughly stained or dirty area, as it is super easy, fast and efficient, with great professional results.

However, a pressure washer is only as good as its pump, as that is where the high-pressured flow of water comes from and it is what determines the power and efficiency of its use.

But for those that aren’t as experienced or knowledgeable in the field of pressure washing, it can be tricky to know what pressure washer pump to buy, or which one is the best option for the best possible results. 

With so many options in the market, it’s important to know which factors determine a good product, and what features to look out for so that the pump you buy is suitable for your pressure washer and your cleaning needs.

To help you out, we’ve summarized the main features and factors to take into consideration when buying a pressure washer pump, in this small buyer’s guide. 

Pressure levels:

When it comes to pressure washers, it’s pretty obvious that the pressure levels are going to be important. It’s important to look at the maximum power pressure a pump can handle, which is always measured in PSI.

The higher the pressure, the stronger the cleaning power is, and the faster a pressure washer will be able to get rid of dirt and stains.

However, sometimes less pressure can be more convenient, depending on the type of surface you’re wanting to clean, or the amount of power you want it to have.

Material and construction:

A pressure washer pump should be sturdy and durable, able to support the high-pressure flow of water that it is creating, and able to withstand the majority of common cleaning or detergent chemicals that you might want to use with the pressure washer for better deep-cleaning.

Stainless steel is a material you should always look out for, as it is a sign of good quality and good build. You should also keep an eye out for anti-corrosion or anti-abrasion features, as they will be the ones that enable you to use a wider range of chemical products with your pressure washer. 

Compatibility:

It’s vital that the pump you buy is compatible with the pressure washer you own or are planning on buying, as it would be pretty useless to buy a pump you can then not attach and use.

Some pressure washer pumps come in more than one mounting configuration, and this is a handy feature to look out for as it means it will be a lot more versatile and a lot more compatible with more pressure washers. 

Safety features:

Using a pressure washer should always be an easy task that you can perform feeling confident and safe, without having to worry about the risk of something going wrong.

If you’re worried about its use, we recommend you look for a pump with some safety features, so that it gives you that extra peace of mind.

Built-in pressure control valves are amazing to have included, and something we recommend you look for in a pump. Otherwise, there are other features such as thermal safety control.

Another thing that comes in handy, adds to safety, and makes a pump a lot easier to use, is the EZ easy startup feature. This allows you to start up the pump engine, without having to hold down on the trigger gun. 

Frequently Asked Questions

Can I adjust the pressure on a pressure washer pump?

Some pressure washers can adjust the pressure PSI by using a pressure regulator that’s situated on the pump.

However, if your pressure washer pump doesn’t come with a pressure regulator, you can reduce the pressure of the water by being further away from the area you wish to clean, or by changing the pressure nozzle tips to alter the pressure impact when cleaning.

How many PSI do I need to clean a concrete driveway?

On average, the PSI needed to pressure wash outdoor areas effectively is 1500 PSI and above.

However, to deep-clean concrete to a high-standard, you should aim for using around 3000 PSI, as it takes a lot more force to properly clean out concrete surface in the same amount of time.
