A platform receives at least two water bottles. A handtruck is configured to engage under a water bottle on the platform and carry it to the dispensing cabinet. In the handtruck, the water bottle is tilted so that the lowest corner of the bottle is directly below its neck. The handtruck engages and locks into the cabinet with the water bottle in proper, tilted position. A suction tube is dropped straight down into the bottle so that it reaches the lowest corner of the bottle. The suction tube carries a pump and discharge spout so that actuation of the pump causes dispensing of water.
