The pressure washer trigger – the lever on the spray gun that you pull to release water – is the control point for the entire machine. It’s simple, but critical for safety and operation. A pressure washer trigger lets you control flow on demand, and the safety lock prevents accidental discharge. Understanding how it works and maintaining it helps ensure safe, reliable operation.
Over time, triggers can stick, leak, or fail. Replacing a trigger or gun is often straightforward if you match the rating and connectors. This guide covers the basics.
