Frequently Asked Questions (FAQs)

1. How does a pressure regulator work on a pressure washer?

Pressure Washer Unloader Valve - Pressure Regulator. ... Spray guns start, stop, and direct the flow of water from the pressure washer's nozzle. Squeezing the trigger releases pressure. Releasing the trigger interrupts the flow of water to the nozzle, although the pump continues to run.

2. What does unloader valve do on pressure washer?

A pressure washer unloader valve diverts the water flow through the bypass when the trigger on the gun is depressed. The Unloader valve is designed to respond to an increase in pressure or a change in water flow. The unloader valve can also be used for adjusting the pressure of your machine.

3. How do you know if your unloader valve is bad?

Water leaks and inconsistent behavior are also signs of a potential failure in the near future. González: The typical signal when there is an unloader malfunction is a reduction of flow through the nozzle, which results in pressure loss. Dean: Typical symptom of an unloader failure is a sudden smooth pressure loss.

4. What causes pressure regulator failure?

There are several reasons that a pressure regulator goes bad. One common cause is age. As the regulator is severely tested over the years by pressure fluxuations, it can end up suffering from stress and decay. This natural aging process makes it necessary to replace it as soon as possible.
