Description The Drinking Post is an automatic frost-free waterer for horses and livestock that doesn't require any electricity! The Drinking Post provides the freshest, cleanest water possible for your animals and saves you time and money. The Drinking Post fills with new, fresh water every time your animal pushes the paddle, and then drains away any excess water that isn't consumed.
