Freeze-Proof Pressure Solar Pumping for Livestock

Popular with winter pastures! Use a pitless adapter (A) drilled into the side of the well casing below the frost line. From there, plumb to a buried cement container, vertical culvert pipe or sump pit (B) that protects the Reverse Action Pressure Switch, pressure tank and batteries from hard freezing. Trenched pipe from there to distribute water to stock tanks, frost-free hydrants and waterers around the property (C). Longer distances from pump to furthest tank may require larger pipe diameter to account for frictional losses with higher flow rates, or larger pumps to provide higher volume with this increased head.
