ABSTRACT:
A freezeless animal waterer has a vertical container having a top, bottom, sidewalls and an interior compartment. A vertical tube is located within the compartment and extends upwardly from the bottom to the top of the container with both the top and the bottom of the vertical tube being open. A pressurized water supply pipe extending from a riser tube in the ground extends through the vertical tube, and upwardly out of the upper end thereof, and thence downwardly back into the container and into the interior compartment, and terminates in an outlet opening. The cross sectional area of the pressurized water supply pipe is less than that of the vertical tube or the riser tube. An electrical heating element is positioned in the compartment to warm the water therein. At least one animal operable watering valve is located in the sidewall of the container to permit animals to selectively withdraw water from the compartment.
