I have no manner of luck when it comes to my regulator. It's been running fine for weeks, but when I opened up the stand this morning to dose, I noticed the pressure was way down. Somehow the connection got loose over the past few days, and there was another leak at the main connection. Frustrating, as it had been flawless until today. Still have at least a week's worth in the tank. Thermal expansion? Gremlins? I dunno.
