ABSTRACT:
A drink dispensing cart includes a drink dispensing machine that is normally plumbed directly into a municipal water pipe at a fixed location. The cart includes a container of water, preferably a disposable container of water such as a bag-in-box container of water, and a pump to pump water from the container of water to the drink dispensing machine. A controller controls operation of the pump to operate the pump only when water is needed by the drink dispensing machine and to provide an indication when the container of water is empty and needs changing. A pressure sensor in an outlet line extending between the pump and drink dispensing machine senses when water is needed by the dispenser and a pressure sensor in an inlet line extending between the pump and the container of water senses when the container of water is empty and needs replacing. A time delay circuit delays start of operation of the pump when water is needed by the drink dispenser to avoid pulsing of the pump. The bag-in-box container of water is sized for efficient packing and shipping.
