Things that will ruin your day
by Jamie Martin, Brewmaster, Dells Brewing Co.
Bubbles: If you ever have just one tank that won’t cool down first thing to check is if there are air bubbles in the glycol line. I used to always forget about this and I would spend all day troubleshooting the wrong thing.
Check valves: Insure all carbonation stones and couplers have working check valves; you do not want to end up with beer in your regulators or gas lines.
