Abstract: The invention relates to portable apparatuses for dispensing purified water from conventional five gallon water bottles directly into a spigot mounted on a sink or an ice maker of a refrigerator. The bottle of water does not have to be mounted on any known support or cabinet, but can remain in its upright position. The water is pumped directly from the bottle through a flexible tube upon drop in pressure in the transport line. A sensing mechanism detects this drop in pressure when the spigot is open and activates a motor which drives the pump. Second pressure switch de-activates the pump when the water runs out of the bottle to prevent overheating of the motor. The pump then has to be manually reset. A time release is provided when it is desired to connect the bottle to an ice maker, so that the pump continuously operates for several minutes to fill in the ice maker and then automatically stops.
