Abstract: A livestock waterer has a first compartment which is typically buried below ground level and has a pressurized water line entering therein. A second compartment is mounted above the first compartment and over an opening in the top of the first compartment so that air in the first compartment is in communication with the air surrounding the second compartment. A third compartment with its bottom portion also buried in the earth surrounds the second compartment and has an open top communicating with an open top of the second compartment. The water line in the first compartment is in communication with the interior of the second compartment. A float valve on the fluid line controls the level of fluid entering into the second compartment. A flexible skirt device surrounds the space between the opening in the second compartment and the opening in the third compartment. The three compartments are free from heat elements.
