Retro Valve venting out back

[robertreed711]

This valve has been working fine for the longest time and just started doing this. It vents at what seems like full pressure out the rear as soon as I turn the air on but if I pull the trigger it stops and works fine until I turn the air off and back on again. I assume that means something isn't quite seating correctly but not sure how to remedy it. Any ideas?

Thanks!

take the back of the valve apart and check the orings and everything for wear, if not you could have a reg thats going

I did that once and looked everything over and wiped it down and put it back together. It seemed to fix it temporarily but then it started doing it again. Any idea what o-ring I should specifically target?

There is a clear diaphragm inside the reg piston. Try opening it up and flipping it.

Replace the regulator piston. Email me if you need one.

Will do. Is it worth trying to open up the old one first?
