Pros & Cons

👍 Pros

  • Float-controlled automatic refill eliminates the need for manual tank checking and filling
  • Three waterers per pack allow you to set up multiple watering stations at once
  • Standard garden hose connection makes installation straightforward with no special plumbing
  • Included metal brackets support both fence-mount and wall-mount configurations

👎 Cons

  • Mounting hardware such as screws and bolts is not included and must be sourced separately
  • 4-gallon capacity may require frequent refilling cycles for larger herds or hot weather conditions
  • The 30-inch included hose is short, so the spigot or hose extension must be close to the mounting location
  • No built-in heating element, so water can freeze in cold climates without a separate heater

Yes. Each unit comes with metal brackets that support both over-the-fence and on-the-wall mounting. Note that the mounting hardware (screws, bolts) is not included.
The 4-gallon capacity works for supplemental watering or smaller herds. Horses can drink 5-10 gallons per day, so a single unit may need to refill multiple times. The automatic float ensures a continuous supply as long as the hose is connected.
