Cleaning equipment is connected to automatically clean conduits which deliver beer from a keg to a spigot. An operator may manually commence the cleaning operation by controlling valves connected to the keg and to a source of water. The spigot is then manually opened by the operator to permit the water to flow through the conduits being cleaned and dispensed at the spigot. The water pressure at the entrance to the conduits creates a vacuum effect to cause a chemical solution to be mixed with the water in accordance with the amount of water pressure. A gauge measures the water back pressure at the entrance to the conduits. The amount of chemical concentration in the solution may be determined when the cleaning equipment is installed from systems involving different numbers of conduits having different back pressure levels.
