What does pressure washer unloader valve do?
What does pressure washer unloader valve do?
The unloader diverts the flow of water from the outlet side of the pump back to the inlet side, causing water to flow in a loop back to the pump under virtually no pressure rather than to the nozzle under operating pressure. Flow may be directed back to the pump inlet or to a float tank or other type of reservoir.

What happens if unloader valve is bad?
A failed unloader valve can cause high pressure at the nozzle. The unloader valve recirculates water to the pump inlet when the pump is running but the spray wand isn’t in use. A defective pressure regulator can cause high pressure at the nozzle.
How do I know if my pressure washer unloader 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.
How do I adjust the pressure on my unloader valve?
How to Set the Unloader Valve or Pressure Regulator
- Make sure the engine or motor is spinning at the proper rpm.
- Use a new high power washer spray nozzles of the proper size orifice for your pressure washer.
- Remove the nylock nut off the top of the unloader valve and spin the black plastic pressure adjusting knob off.
How does an unloader valve work?
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. Trapped pressure unloaders are opened by the increase in pressure when the trigger is released on the gun.
How do you adjust the unloader valve on a pressure washer?

How does a pressure washer unloader valve work?
How a pressure washer Unloader Valve works. 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.
What is a general pump unloader?
The unloader is a valve that directs flow to either the nozzle or to bypass. Pressure is developed in a pressure washer system as a result of forcing a constant volume of water through a fixed orifice (nozzle). This is accomplished by the use of a positive displacement pump such as the TS1011.
What is hydraulic pressure regulator?
Hydraulic Pressure Regulator Pressure regulators, often referred to as unloading valves , are used in fluid power systems to regulate pressure. In pneumatic systems, the valve, commonly referred to as a pressure regulator, simply reduces pressure.
