How to Choose a Pressure Washer


Before you begin your pressure washer project, you should decide on a few factors. Some factors to consider are the amount of pressure, the size of the nozzle, and the GPM. If you’re buying a new pressure washer, make sure that you read the user manual carefully and follow all of the manufacturer’s instructions. Once you’ve determined these important factors, it’s time to start your project! Read on to learn more about how to choose a pressure washer and start enjoying the benefits of your new tool.

Powerful jet of water

A power washer is an electric tool that uses high pressure water to clean various surfaces. It has a hose that sprays water that is pressurized at approximately one hundred to two hundred pounds per square inch. Pressure washers have a range of attachments that increase the water pressure. Some pressure washers can clean concrete, masonry, and other surfaces. A pressure washer can also be electric or gas powered, depending on your needs.

If you are going to use a pressure washer to clean a building, you should buy one that is gas-powered, as they can work more efficiently. Also, check the safety margins of the hoses you choose. You might want to buy a hose that is rated for 6000 psi if you’re using a 2000-psi pressure washer. If you are planning to use the pressure washer to clean the exterior of a building, you should opt for a gas-driven unit.

Size of nozzle

If you’re looking for a pressure washer that produces high pressure, the size of its nozzle is a crucial factor in ensuring a good power washing experience. A smaller orifice will increase pressure, while a larger orifice will reduce water flow and put too much strain on the machine. The table below indicates the recommended size of nozzles for various types of pressure washers. If the PSI of your pump is 2500 and the GPM is 2.8, then the nozzle size should be 3-4.

The nozzles are color-coded according to degree. For example, a red-tipped 0Adeg unit is recommended for cutting surfaces. In contrast, a green-tipped 25-Adeg unit is good for washing vehicles. In addition, a white-tipped nozzle is the best for washing surfaces that need a low-pressure wash, like those found on cars. However, it’s important to note that a white-tipped pressure washer nozzle is designed for rinsing, while a 65-degree unit is designed to clean sensitive surfaces.


One of the most important features of a pressure washer is its flow rate. It is measured in Gallons Per Minute (GPM), which is what determines the length of time it takes to clean a particular job. GPM is calculated by comparing the operating pressure of the pressure washer system in PSI and gallons. The lower the GPM, the less powerful the pressure washer will be. However, there are some things you can do to reduce the water consumption of your pressure washer, such as using a high-quality detergent and a hose.

The GPM of a pressure washer can be important for cleaning delicate surfaces, such as windows and siding. If you don’t know what kind of surface you need to clean, you should choose a pressure washer with sufficient GPM. Having more than 3 GPM will ensure that you get the job done quickly. However, it’s always advisable to choose a high-end pressure washer with a higher GPM.

Power cord

Purchasing the proper power cord for your pressure washer is essential for its safe operation. This cord must be heavy duty and waterproof to withstand the force of the pressure washer. It is also essential to wear rubber-soled shoes when operating the pressure washer to provide insulation. In addition, you should never remove the grounding prong from the power cord plug. In addition, you should not operate your pressure washer after it has tripped its circuit breaker or ground fault interrupter.

The electrical cord assembly on a pressure washer consists of a long wire cord with a GFCI-protected plug. GFCI protects the pressure washer from electrical shock and automatically shuts off power if it senses a ground fault or voltage loss. However, it is important to keep in mind that a ground fault circuit interrupter can be tripped by excessive moisture, internal wire damage, or faulty building wiring.

Cleaning solution

There are several types of cleaning solutions for pressure washers. Some cleaning solutions are concentrated, which means that you will need to dilute the solution before using it. Others are ready-to-use, which means that you can apply the solution directly. Both methods have their pros and cons, but detergents are usually more effective, while soaps tend to leave behind residue or streaking, which can make the job more difficult. Also, your cleaning solution will need time to do its job properly, so you should mix the cleaning solution at least half an hour before use.

When choosing a cleaning solution for pressure washer, you will want to consider the type of surface you want to clean. Multipurpose detergents work well for most surfaces. They are effective at removing all kinds of dirt, oil, grease, and various kinds of stubborn stains. The formula of these detergents is biodegradable and does not contain toxins or petroleum solvents. Furthermore, they are gentle on your pressure washer, reducing the need for heavy scrubbing.
