An insulated watering system is provided for fowl, animals or the like in which a length of pipeline is defined by several groups of watering pipes with each group of watering pipes being of a different wall thickness and having greater heat-insulating efficiency in the direction of water flow. The pipes are preferably formed from foamed polymeric/copolymeric material, such as polyvinylchloride, and each includes an interior cylindrical closed cell core sandwiched between noncellular skins or plies. The exterior diameters of all watering pipes are identical, but the interior diameters of the various groups decrease in the direction of water flow. In this fashion, a larger wall thicknesses of the pipes effectively insulate the lesser volume of water flowing through the water line along downstream portions thereof.
A watering system for fowl, animals or the like comprising a plurality of lengths of tubular watering pipes, means for connecting said watering pipes to form a relatively long watering line through which water is adapted to flow in a predetermined direction, a plurality of drinker means along said watering line for delivering water from said watering line to fowl, animals or the like, said tubular watering pipes being of generally the same exterior diameter, said tubular watering pipes being of at least two different interior diameters to thereby define a first group of watering pipes of a first relatively small wall thickness and a second group of watering pipes of a second relatively large wall thickness, and said second group of watering pipes being disposed downstream relative to said first group of watering pipes in the predetermined direction of water flow whereby the relatively large wall thickness effectively insulates the lesser volume of water flowing through the water lines along downstream portions thereof.
