  • Patent number: 3945536
    Abstract: A tank is provided which may be filled with water and pressurized from a CO.sub.2 bottle or the like and it may be connected to the system to be cleansed by means of conventional quick connector hoses. An inner container is provided which holds a cleansing solution and a valve system is located within the inner container connecting and disconnecting same to the outlet of the main tank. When pressure is applied to the main tank, a one-way valve in the container permits this pressure to act upon the liquid within the container which is then forced into the valve system and thence to the outlet of the main tank mixing with water from the main tank as it passes from the outlet. The discharge of the liquid is controlled by the dispensing taps of the system to which it is attached. When the cleansing solution is exhausted from the inner container, the valve system closes and the remaining water in the main tank is then forced through the system to purge the lines of cleansing liquid and dissolved deposits.
