Keep your livestock watered with fresh water without having to constantly pump or manually refill the tank. With the Little Giant FW16RED 4-Gallon Auto Float Controlled Waterer 4-Pack, you can hook it up and forget about it. This automatic water trough is hooked up with the included 30-inch hose to a standard 3/4-inch water hose or faucet. That means you can easily get water to this float-controlled water trough without any complicated plumbing. A 4-gallon capacity makes this auto livestock waterer ideal for horses and cattle, and when the water level drops below a certain level, the waterer will automatically refill itself from the hose. This 4-pack of automatic water trough includes metal brackets for over-the-fence or on-the-wall installation (hardware not included). So wherever you have hose access and a solid object on the farm, watering the horses just got a whole lot easier.
