What is an insulated earth tube and why should I use it on my J&D Poly Livestock Waterer?
An earth tube is located under the ground around the water supply line. It is highly recommended for cold climates. You many need more than one depending on the depth. This tube allows the movement of air that has been warmed by the geothermal heat around the water supply line to keep it from freezing. The warm air is generated from the ground below the frost line.
