Miraco MiraFount 3370-S — Six-Hole, 100-Gallon Energy-Free Cattle Waterer
The Miraco MiraFount 3370-S is a large-capacity insulated livestock waterer designed for beef cattle, dairy cattle and cow-calf operations. Its 100-gallon reservoir and six drinking openings offer several animals access at the same time. Two internal valves help the waterer recover as cattle drink. The six floating ball closures help insulate the drinking openings; they are not six separate water-supply valves.
The MiraFount design uses insulated polyethylene construction and incoming ground-temperature water to help moderate water temperature without an electric tank heater under suitable conditions. Proper installation, adequate livestock use and daily inspection remain essential, particularly in freezing weather.

Livestock-capacity figures are the manufacturer's model ratings, not a guarantee for every location or herd. Peak water use, supply rate, water pressure, weather and access patterns can reduce the practical number of animals served.
Why Choose the Six-Hole MiraFount Waterer?
- Six covered drinking stations: The floating ball closures help shield the water from outdoor air when animals are not drinking.
- 100-gallon reservoir: Larger capacity supports watering operations with multiple animals approaching the tank.
- Two refill valves: The 3370-S uses two water-supply valves for faster recovery as cattle drink.
- Removable end panels: The manufacturer describes these as useful when introducing cattle to the waterer or temporarily increasing access.
- Energy-free design: Properly installed, the waterer is designed to operate without an electric tank heater by using insulation, incoming water temperature and regular water turnover.
Installation and Winter Watering Requirements
An energy-free waterer is not automatically freeze-proof. Its cold-weather performance depends on the insulated installation, incoming water temperature and the number of animals using it. Miraco's guidance for MiraFount systems calls for water lines buried below the local frost line, an appropriately protected or insulated heat well and regular animal use. In subzero weather, Miraco commonly specifies at least 20 head using the waterer, with model and climate requirements taking precedence.
Before installation, verify the supply line, available flow rate and pressure, pad preparation, insulated earth tube, anchoring and valve access against the Miraco 3370-S manufacturer information and installation guide. Inspect drinking closures, valves and water availability regularly, especially after storms or in prolonged cold. Where animal numbers or installation conditions are inadequate, consider an appropriately sized electrically heated livestock waterer.
Choosing the Right MiraFount Capacity
If you do not need six drinking positions, compare the four-hole 70-gallon MiraFount or two-hole 44-gallon MiraFount. Compare actual animal use, drinking access, herd size, source-water delivery and installation footprint—not only the gallon rating.
Frequently Asked Questions
Is this the 15-gallon or 100-gallon MiraFount?
This listing is for model 3370-S, a 100-gallon six-opening waterer. The previously listed 15-gallon capacity was incorrect for this model.
Do the six ball closures regulate the water level?
No. They are drinking-port closures. The two internal refill valves regulate incoming water as needed.
Does it need an electric heater?
The MiraFount 3370-S is designed for energy-free operation under suitable installation and livestock-use conditions. Extreme cold or too little water turnover can still cause freezing. Follow the manufacturer's guidance.
How many cattle can use this waterer?
Miraco lists up to 250 beef cattle, 120 dairy cattle or 200 cow/calf units. The practical capacity depends on water supply, animal access, weather and when the herd drinks.
Is the unit suitable for hogs?
This model is listed by Miraco for beef and dairy cattle. For hog-specific units with lift-up lids, see MiraFount hog waterers.
