This past weekend I had to crank up the pressure to around 30 PSI to get a stubborn keg to seal.
This was a first for me since I have always been able to get a seal at 10 PSI.
Anyway, after the keg sealed, I tried to turn the pressure down but I can not return the adjusting screw back to its original setting.
I was able to back it off to a 20 PSI setting but it is stuck there and and I can not get it to move in or out.
Any suggestions?
