Honda GX690 Pressure Washer - gauge flew off

You’re lucky. If I shut the machine off with pressure still in the line, it won’t start.

The ZK1 is a heckuva good luck charm.

I’m unsure which unloader I’ve got as part of this set up. I wonder if I could add a pressure relief valve in the spot where the pressure gauge blew off. Would that work?

I panicked when I saw the pressure gauge shear it’s thread and fly into the air. Water was jetting everywhere… so I closed the main valve for a bit and then pressed the emergency stop button. Haven’t started it since. Joined this forum. It’s been very helpful. Thanks.

Same here, except I only run at 1/2 throttle about 30 sec before wide open

Yep. The difference in pressure between the unloader block and the nozzle can be dramatic.
