The WaterPro2 Open Top Waterer is ideal for use with equines and is often installed in or nearby a stable or shed. Designed to withstand the harshest weather conditions, these energy-free units provide a reliable fresh water supply to your valuable animals year-round. The drinking height is at a comfortable 21.65″ making it an ideal water source for larger animals like horses. An optional immersion heater can be installed to keep the ice off the Open Top Waterer. The insulated and securely sealed exterior drain plugs can also be used as interior plugs. This provides the flexibility to seal off one side for cleaning and maintenance without having to turn off the water supply.
