Any help or insight would be most appreciated! Here's my story:built a kegerator out of an old mini fridge. Have a dual gage regulator. I set it at 12psi and was running my fridge temp at 34. The next day I checked pressure and it was at 15psi, which was too much. So I set it again at 12psi and changed my temp to 36. The next day it reads 10 psi. Are these fluctuations normal? Why can't I get it to just stay where I set it? I am hoping when I get home today it at at least stays at ten psi and doesn't drop any lower! Do psi levels just randomly change like this? I am new to this, thanks for your help!!
