Abstract
A self-cleaning, low-maintenance, water-saving automated animal watering device () is provided which includes a watering tank () moveable between a lower, water-full condition and an upper, water-low condition. Preferably, one end of the tank () is pivotally supported by a pivot shaft (), while the other end of the tank is biased upwardly via a lower lift spring (). The device () also has a water fill assembly () operably coupled with tank () to selectively fill the tank () when needed, and a drain valve assembly () also coupled with tank () in order to completely drain the tank () on a periodic basis. A control assembly () is coupled with at least the tank () and drain valve assembly (), and is operable to actuate the drain valve assembly () after a predetermined number of movements of the tank () between the elevated and lowered positions thereof.
