Another question, O wise brewers!!
I noticed a significant drop in my tanks PSI from about 650 to 500 overnight. I charged the keg and disconnected the tank to see if the pressure comes back up after the tanks warms back up, thinking the cold temp may have caused it. If it turns out that the pressure stays low in the tank, I'll tighten every thing up and test for leaks on the reg connections. But if they test alright, what's the best way to test the keg for leaks with beer already inside?
Any other little tips or tricks would be helpful too.
