Pressure washing, alternatively known as power washing, is the use of high-pressure water spray to remove loose paint, mold, grime, dust, mud, chewing gum and dirt from surfaces and objects such as sidewalks, buildings, vehicles and concrete surfaces.
The volume of a mechanical pressure washer is expressed in gallons or litres per minute, and is quite often designed into the pump, and is not variable.
The pressure, expressed in pounds per square inch, pascals, or bar, is designed into the pump as well, but can be varied by adjusting the unloader valve. Pressure Washers can produce pressures from 750-psi to 30,000-psi (5 to 200 MPa) depending on the application and what the objective of the pressure washing is
At SoCal Cleaning and Restoration, all our field technicians are trained to use the right pressure settings to pressure clean any and all surfaces. Different types of nozzles are available for different applications. Some nozzles create a water jet that is in a triangular plane (fan pattern), others emit a thin jet of water that spirals around rapidly (cone pattern). Nozzles that deliver a higher flow rate lower the output pressure. Most nozzles attach directly to the trigger gun.
If you have any questions, our field technicians can answer them for you or you can call us to discuss your application in more detail.
