So I just kegged a batch for the first time yesterday, and I'm trying to force carbonate it with the set-and-forget method. I put the keg & tank/regulator in the fridge at about 5:30pm yesterday and set the keg-side pressure to about 12.5 psi, tank and regulator open. I checked on it at midnight, and the tank-side pressure had fallen quite a bit, as expected, but what surprised me is that the keg-side pressure had also fallen to about 10 psi. Now this morning, about 9 hours later, I just checked again, and the keg-side pressure has fallen to 8 psi (the tank-side pressure doesn't look like it's changed).
Why is my keg-side pressure slowly falling? It was my understanding that the low temperature in the fridge would only lower the tank-side pressure, because of the gas/liquid mixture in there, but not the keg-side pressure. Does the low temperature somehow affect the diaphram in the regulator (Midwest supplies' double-dual-gauge), such that I have to open it more to keep the same amount of pressure on the keg? Or do I simply have a leak somewhere? (This being my first time kegging, I scrupulously slathered every seal with soapy water, but didn't find any bubbles; and if I had a leak, I would expect the tank to be empty now, rather than this slow loss of keg-side pressure.)
Thanks for any advice to a newbie.
