Abstract
Abstract First and second kegs, each having a keg adapter mounted in an opening in a wall of the keg. A tapper in operative engagement with each keg adapter. Each tapper and associated keg adapter providing an inlet passageway for the transfer of fluid from outside to inside the keg, and an outlet passageway for the transfer of fluid from inside to outside the keg. Each inlet passageway containing a valve yieldably biased toward the closed position to prevent flow from inside to outside the keg. Each outlet passageway containing a normally closed valve which is manually movable to the open position. A fluid pressure source is connected to the outer end of the inlet passageway of the first keg to cause the fluid in the first keg to flow through the outlet passageway. The outlet passageway of the first keg is connected with the inlet passageway of the second keg to transfer fluid from the first keg to the second keg. And, the outlet of the second keg is connected to a fluid dispensing faucet.
