There are several main reasons why you want to adjust the pressure on a pressure washer.

Damage Prevention

The most important reason for adjusting the pressure on a pressure washer is to avoid damage. Not all surfaces are indestructible. While concrete and asphalt might be able to handle a lot of pressure, not all materials can. Paint, vinyl siding, and wood can’t handle too much pressure. They will break, chip, and be otherwise damaged.

Better Cleaning Power

The more pressure a pressure washing question has, the better it can clean. Therefore, being able to adjust the pressure on a pressure washer is very important. Different cleaning jobs require different levels of power. You might have to adjust your pressure washer up to a very high level to clean those oil stains from your concrete driveway. It’s all about being able to maximize cleaning efficiency.

Energy and Water Conservation

Energy and water conservation should also be taken into account. If you only use as much pressure as is needed, you won’t use too much energy or water.

Longer Lifespan

Some pressure washer accessories can only handle certain amounts of PSI. Therefore, being able to adjust your PSI means prolonging the lifespan of various components.

How to Adjust the Pressure on Different Pressure Washers

There are two main types of pressure washers, and you need to know how to adjust the pressure on both of them. Here, we are talking about gas pressure washers and electric pressure washers.

Gas Pressure Washers

Gas pressure washers usually have many options for adjustment. You can adjust the pressure regulator, the spray wand, or the nozzle tips. Let’s take a look at how to do each of these.

  • To adjust the pressure regulator, first locate. You’ll usually find a regulator knob near the pump. To increase the pressure, turn the knob clockwise, and vice versa. Start low and then adjust as you see fit.
  • You can also adjust the spray wand itself. Some gas pressure washers have spray wands that allow you to change the pressure. Some models also come with lawns that you can rotate to adjust the pressure. Keep in mind that the wider the spray pattern, the lower the pressure.
  • To adjust the pressure, you can also change nozzles. Different nozzles have different pressure levels and different spray angles. This is something to consider when you are first choosing the pressure washing question.

Electric Pressure Washers

Electric pressure washers generally offer fewer adjustment options, although it is still possible. You can adjust either the pressure regulator or the nozzle.

  • Just like gas-powered models, electric pressure washers also have a regulator knob. The regulator knob is found on the spray wand or near the water outlet. Turn the knob counterclockwise to decrease pressure, and vice versa.
  • Electric pressure washers usually allow you to change the nozzle as well. Remember that different spray angles feature different pressure levels. But the wider the angle, the lower the pressure level.

How Much Pressure Should I Use?

Now that you know how to adjust the pressure on a pressure washer, let’s figure out how much pressure you should use for each of the following applications.

Garages

For a garage ground, use between 2000 and 3000 PSI. You need a relatively high-pressure setting to break down oil and grease stains. Try to start with around 2000 PSI, although you might need to move up to 3000. Concrete is quite resilient, so it shouldn’t take damage from your pressure washer. You also need a unit with a relatively high GPM.

Driveways

Asphalt and concrete driveways can take even more pressure than your garage. Also, mildew, oil stains, dirt, and more can all build up on driveways. If you need to clean your driveway with a pressure washer, use a setting of up to 4000 PSI. You can start with 3000 PSI, but that might not be enough for tough stains. You’ll also want to use a nozzle with a narrow-angle.

Wooden Decks and Patios

Remember that wooden patios and decks can be relatively fragile and delicate. Therefore, you want to use a wide-angle nozzle and not too much PSI. Start with around 500 PSI. Make sure to hold the one no closer than 12 inches from the surface. If needed, you can go up to 2000 PSI. However, beware that you may cause damage to wood.

Siding

For exterior siding, don’t go above 1600 PSI. Although, for aluminum and vinyl siding, you may need around 1300 PSI at the least. You also want to use a nozzle with a wide angle. This will help avoid damage from being caused to the siding. Always remember to start at the top and work downwards.

Vehicles

For your vehicles, don’t exceed 1900 PSI. You don’t want to strip the paint right off of your car. For this reason, also use a relatively wide-angled nozzle. You also need to hold it at least 12 inches from your car to prevent any pain from being stripped off.

FAQs About Adjusting Pressure Washer Pressure

Here are some of your most frequently asked questions about pressure washers and PSI.
