When running for an extended time is it ok to do a quick moisture purge by opening the bleed valve and then closing or is that equivalent to running under a quick heavy load of back pressure?
Extended GX-CS4 fills.

Good point didn’t think of that. I was thinking it probably would be ok. I ran mine for the first time today for about an hour and ten minutes. Never thought of purging and at the end there was a decent moisture buildup.

I have no problem with purging while the motor is running. Usually, I will close the tank valve, then purge, close the purge valve and let the whip fill up to almost the tank pressure before I open the tank valve again. I feel 100% safe with that methodology.
I believe firmly that the issue comes from trying to start from a cold stop, against high-pressure air already loaded against the exhaust valve. The motor and linkages have to overcome inertia and the back pressure from the exhaust end.

A one way check valve on the tank fill adapter removes the need for closing the tank valve while purging. You won't lose any air already in tank.

...or I can avoid another point of potential failure and more cost, and purge the water trap as explained. Yes a one way valve is an option, but why?
The back pressure would come from the release of pressure at the purge and the premature opening of the bottle valve, hence why I let the pressure in the fill whip build to nearly what the tank pressure is.
