What an Unloader Valve Does
An unloader valve is a critical pressure washer component that:
- Regulates system operating pressure
- Diverts water flow during bypass operation
- Protects pumps from pressure spikes
- Reduces wear on hoses, guns, and fittings
- Maintains safe operating conditions
- Extends equipment service life
When the trigger gun is released, the unloader redirects water flow through the bypass circuit until spraying resumes.
