So for my first venture into kegging I built a 4 tap keezer. I put it all together the first week of October and hooked up all 4 of my kegs. When my wife went to pour a pint today the tank was empty. I have a 10# tank and four taps set at 11-12 psi. 2 of the kegs were primed with sugar before they were hooked up. Is it just me or does that seem like the co2 ran out too fast?
