Wow, I never dreamed Oklahoma would get that cold.
Did you install it in a barn or in a pasture? I guess I'm thinking that a
waterer that is covered might be less likely for the paddle to freeze from the
moisture in the air.
I installed one of these units in 1994, in Oklahoma where our
freeze line was 24", and a 300 gallon tank would freeze solid. The "how it
works" screen describes better than I can...valve is below freeze line. Warm
water enters the bowl for drinking - then when paddle is released the water
drains out of the bowl. The bowl is empty before the paddle gets cold or any
freezing could occur. Best
