I’ve got a Micromatic single pressure regulator connected directly to my keg – no manifold and only a non-return valve on the line. My problem is that after I’ve dialled in my pouring pressure, if left connected with the gas on, the pressure in the keg creeps up over time. The pressure gauge on the reg reports upward of 200 kPa after a few hours, when the pressure I set was 50 kPa and the keg was pouring beer perfectly. I was taken a bit by surprise when I tried to pour a beer the day after I got my shiny new system working beautifully (or so I thought) .
I’ve RTFM and found nothing useful. Am I stuffing something up, or does this sound like a faulty reg?
