I read somewhere that the high pressure gauge on the regulator will read at a lower PSI at cooler tempuratures. Does this work the same for the regulators going to the kegs? I'm asking because I'm force carbing my first batch and the pressure on my regulator keeps dropping a point or two over every 8 hours or so. I've been cranking it back up to adjust for the loss in pressure. Should I be doing that, or should I leave it alone. I'm carbing at 45 degrees and 13 PSI.
Someone else just posted with the same issue. Yes, I think it's normal, when the diaphragm in the regulator is cold it can take a day or two to stabilize. Adjust as needed, and I bet you'll find that it's fine after a couple days.
