ABSTRACT:
Apparatus for supplying water to a carbonator tank in a liquid dispensing system includes a water supply delivery control circuit which generates a periodic supply enabling signal of a relatively short duration when the water level in the tank falls below a predetermined level and an enabling signal of a comparatively longer duration when an initial filling of the tank is desired or a system reset switch is manually activated. Both periods are selected so as to prevent damage to the delivery pump, for example, due to an overload condition caused by an interruption of the water supply.
