I've had my CO2 tank hooked up to a 3-keg keezer for 6 months with no issue - and then one day I went downstairs and the CO2 is empty - but I haven't used nearly enough for it to be empty - and last time I checked the gauge (a week ago) there was plenty of gas left.
My question is - is it possible for one of my taps (perlicks) to be open enough to leak out co2, but not to be dripping beer? Is there a chance that's how I lost the gas?
Thanks!
