Provide a constant supply of clean, cool water to your pets and livestock with the Little Giant Cast Iron Automatic Stock Waterer. This dog water bowl dispenser is a reliable source of hydration that's ideal for a single pet or a whole herd. A push-pedal design provides water when your animal presses down, rationing the liquid and preventing standing water from building up and becoming a breeding ground for unwanted organisms. The automatic water trough is safe for use from 20 psi to 50 psi and features a non-siphoning valve to prevent freezing. Keep your cattle's and horses' thirsts slaked at all times with this automatic pet trough installed in your stable or barn. Or install it at a dog-friendly height on your patio to give them a convenient water source while they patrol the yard. Whatever your agricultural and home lawn needs, the Little Giant Cast Iron Automatic Stock Waterer is here to make sure your animals are healthy and happy.
