Someone mentioned that he disconnected his keezer liquid lines before heading off on an extended trip and came home to find 6 inches of beer in his keezer due to failed poppets. I will be traveling for business for several months and plan to disconnect both sets of lines from kegs. I am wondering whether I should discharge the CO2 in each keg as well, recognizing that it may take a week or see to recarb upon return. They will each be no more than half full so the equilibrium keg pressure should eventually get to maybe 3-5 psi or so, from 10 psi. Interested to hear advice on this matter. Thanks in advance.
