Changing a keg is the process of replacing an empty keg of beer with a full one. It is a relatively simple process that can be completed in a few minutes. However, there are a few things to keep in mind when changing a keg to ensure that it is done safely and correctly.
First, it is important to make sure that the keg is properly connected to the CO2 tank. The CO2 tank provides the pressure that forces the beer out of the keg. If the keg is not properly connected, the beer will not flow out.
