An animal waterer comprises a bowl having an open top and a bottom drain, and a valve is operatively associated with the drain for selectively blocking and unblocking the drain. A water supply line cooperates with the valve and is operably associated with the bowl for supplying water to the bowl when the valve blocks the drain so that the bowl thereby fills with water and for causing water to drain from the bowl when the valve does not block the drain. A sensing system is operatively associated with the bowl and with the drain for causing the valve to block the drain when the presence of an animal is sensed so that the bowl is thereby filled with water for the animal to drink and for causing the valve to unblock the drain when no animal is sensed so that the bowl is drained of water.

An animal waterer, comprising: (a) a bowl having an open top and a bottom drain; (b) first valve means operatively associated with said drain for selectively blocking and unblocking said drain; (c) water supply means cooperating with said bowl and operatively associated with said first valve means for supplying water to said bowl when said first valve means blocks said drain so that said bowl thereby fills with water, and for preventing water from flowing to said bowl when said first valve means does not block said drain; (d) second valve means interposed between said first valve means and said water supply means and operably associated with said first valve means; and (e) non-contact sensing means operatively associated with said bowl, said water supply means and said first and second valve means for causing said first valve means to block said drain when the presence of an animal is sensed so that said bowl is thereby filled with water for the animal to drink, and for causing said first valve means to unblock said drain and said second valve means to block said water supply means to prevent water from flowing to said bowl when no animal is sensed so that said bowl is drained of water; said second valve means being operably associated with said sensing means for causing water to flow to said first valve means when the presence of an animal is sensed, and for permitting water to drain from said first valve means and from said bowl when no animal is sensed.
