I brew some batches for a buddy of mine who has a Sanyo 4912 kegerator that can fit two kegs. Depending on my schedule he sometimes has two Cornys and sometimes he swaps them out with a locally-filled Sankey keg. What is the best way to be able to swap the beer line from the pin lock beer out to the sankey coupler without having to pull the cold beer line off the barb every time?
