Pressure Washer Cleaning Hints

High Pressure - Why and how?

Every homeowner knows how difficult it is to clean paths, driveways and patio areas when using a garden hose and a stiff broom, this is because the water pressure from garden hose can only provide a very limited cleaning power. However, a pressure washer provides significantly higher cleaning power, with water delivered at pressures above 1,500 psi and a controlled water flow and is therefore perfect for most exterior cleaning tasks around the house, garden and for cleaning the car.

How does a pressure washer work?

Water from a suitable supply is supplied through a garden hose to the inlet of pressure washer. An electrical or gasoline driven high pressure pump generates water pressures in excess of 1500psi and in some commercial models as high as 4000psi. A high pressure hose delivers the high pressure to the pistol and the lance. With the trigger of the pistol open, the water leaves the nozzle of the lance as a sharp, concentrated jet with high cleaning power. Despite its remarkably better cleaning performance a pressure washer uses dramatically less water than a garden hose thus protecting the environment. Typically a garden hose with 60 psi water supply pressure uses up to 600 gallons of water per hour, whereas a pressure washer uses only about 180 gallons per hour but supplied at a pressure of 1500psi and upwards.
