Can You Run a Pressure Washer Without Water?

Starting a pressure washer without water can be catastrophic. The pump will be the hardest hit. You see, the function of the pump is to push water out through the nozzle from the supply hose.

Denying the pump water is akin to denying it much needed lubrication. It will, therefore, work so hard for nothing since the water meant to flow through it is absent. The result will be massive friction within the pump, causing it to wear down.

The pump struggling to run without water will also have a ripple effect on the motor. The motor is responsible for turning the pump. It will be working so hard to turn a pump that is near impossible to turn due to friction.

In the blink of an eye, you might find yourself with a problematic pressure washer that struggles to clean the smallest of dirt. Major components such as the pump, gaskets, motor, seals might become defective, never to recover.

It might cost you dearly to replace these components or get another pressure washer. We don’t want that for you, bearing in mind that finances might be quite tight right now due to the pandemic.
