Hey guys, I'm having some trouble keeping my C02 pressure correct. I have a light ale on tap right now, it's my first batch ever. I set the pressure at say about 11.5 and it will stay there for about 4 hours. Then, say when I wake up and check it the pressure has risen in the tank to about 18 psi.
Can someone help me out? I lower the pressure down, purge the tank, and up the pressure until I get to about 11.5, then tighten the nut down to lock it in. It always goes up though, I can't figure it out.
The thing that is gettin me is that i'm in thermodynamics right now, which basically all I do is work out pressure problems in seal systems. The temperature is constant in the fridge, the liquid volume changes as I drink but that shouldn't change it as it is replaced with more C02. I don't know what else to do.
Any tips?
