Abstract:
A freeze resistant animal watering installation, comprising:a trough; a substantially vertical flow tube having an upper end in fluid communication with the trough and a lower end adapted for connection to a source of water under pressure; a valve positioned at the lower end of the flow tube which is adapted to control the flow of water from the water source, the valve having an open position and a closed position and being normally in the closed position; a valve actuator adapted to permit activation by an animal accessing the trough to move the valve to the open position whereby water from the water source flows up the flow tube to the trough; a storage reservoir adapted for installation underground below frost level, the storage reservoir being in fluid communication with the lower end of the flow tube and having a capacity that is greater than the combined capacity of trough and the flow tube, such that the trough and the flow tube drain into the storage reservoir; and means for selectively emptying the storage reservoir upon the valve actuator being moved to the open position.
