摘要： A livestock watering system comprising an underground water storage tank having a pump means connected thereto for pumping water therefrom. A first water line extends from the pump to a vertically disposed riser pipe positioned in the ground and extending upwardly to ground level. A waterer housing is positioned over the upper end of the riser pipe and has an interior compartment formed therein which communicates with the upper end of the riser pipe. A second water line is connected to the first line and extends upwardly through the riser pipe and into the interior compartment of the housing. A nipple water valve means is connected to the upper end of the second water line and has nipple valve members extending outwardly through the housing to permit the livestock to obtain water. A third water line is connected to the valve means and extends downwardly through the interior compartment and the riser pipe. A fourth water line extends from the lower end of the third water line either to a return line to the water tank or to another waterer housing. A pipe means extends between the lower ends of the second and third water lines and has a restriction formed therein so that a predetermined amount of water passes upwardly into the second water line and so that a predetermined amount of water bypasses the second water line. The riser pipe and the interior compartment of the housing have cross-sectional areas sufficiently large so that heat from the ground may rise upwardly through the riser pipe and into the interior compartment so that the water in the valve means will not freeze. Most heat energy is in the circulating water itself.
