ABSTRACT:
A wet/dry feeding device for the watering of live stock, primarily smaller animals, such as grower pigs, comprising a vacuum valve1with a diaphragm, water holding reservoir pans4, water leveling tube6, and double walled water feeding tube5. The water level is automatically maintained within the reservoir pans4by an adjustable water feeding tube5which is placed into the water at a perpendicular angle to the water surface. At the top of the water feeding tube5, a vacuum valve1with a diaphragm is located to allow water into the reservoir pans4until the water level enters the feeding tube sleeve, thereby activating the vacuum valve1, and ceasing the flow of water.
