What is Unloader Valve?
The unloader valve is a pressure-activated valve that is designed to regulate the pressure output of the pressure washer pump. It is typically located on the side of the pump and is connected to the pressure washer’s high-pressure hose. The valve is responsible for releasing excess pressure from the pump when it is not in use, helping to prevent damage to the pump and improve overall performance.
How It Works
The unloader valve works by using a spring-loaded piston to regulate the pressure output of the pump. When the pressure washer is in use, the piston is pushed back by the high-pressure hose, allowing the valve to open and release excess pressure from the pump. When the pressure washer is not in use, the piston returns to its original position, closing the valve and preventing pressure from building up in the pump.
Symptoms of Faulty Unloader Valve
A faulty unloader valve can cause a range of symptoms, including:
- Reduced pressure output
- Leaks from the pump or high-pressure hose
- Increased wear and tear on the pump
- Difficulty starting the pressure washer
