Drinking Post is the best auto waterer for horses and livestock. It fills and drains with each use, keeping the water fresh and clean all year long. Since the water drains away, it’s completely empty when it’s not in use. This means there’s never any standing, stagnant water. This prevents algae growth, bugs swarming, dirt and debris collecting, the treat of water-borne illnesses, and much more.
