Overview

Pressure washers have the ability to clean cars, buildings, homes, sheds or any durable area that needs treatment. The pressure washer itself can be altered to change the pressure of the water coming out of the machine. There are two common ways to achieve this.

Adjusting the Motor Valve of the Engine

Step 1

Change the regulator knob to adjust water pressure. Often the knob is located on the outside of the machine.

Step 2

Refer to the washer's customer service number or manual if the pressure washer does not have an external knob to change the pressure. This could be an internal feature.

Step 3

Contact the store of purchase for further assistance. They may be able to provide advice on how to remedy the washer or service it themselves.

Adjusting the Angle and Distance of the Pressure Washer's Water Stream

Step 1

Start washing an area from a distance (more than five feet) and at a wider angle (closer to 90 degrees.) Different surfaces require different amounts of water pressure.

Step 2

Move closer to the surface and shorten the angle of the nozzle (less than 90 degrees) if more pressure is needed (dirtier areas.) This will also concentrate the water for smaller areas.

Step 3

Switch between wide angles and distances and smaller angles/closer distances to thoroughly clean a wide area, depending on the varying surfaces.

Tips and Warnings

  • Too much pressure with a pressure washer can permanently destroy certain surfaces. Use caution and lower pressure when beginning a project.
