Miraco MiraFount 3345 — One-Hole 30-Gallon Cattle Waterer
The MiraFount 3345 is an insulated, non-electric cattle waterer with a 30-gallon reservoir and one covered drinking opening. Designed for beef and dairy operations with a suitable water supply, this polyethylene waterer combines a patented roll-away ball closure, an internal water-level refill valve and urethane insulation to help reduce heat loss between drinking visits.
Important: Energy-free operation is conditional, not a guarantee against freezing. The waterer relies on incoming groundwater temperature, frost-protected plumbing, correct installation and adequate daily use by livestock. It does not contain a built-in electric heater.

Head-count ratings are manufacturer guidance rather than guaranteed performance for every herd. Drinking patterns, peak demand, supply flow and cold-weather conditions affect how many animals can use a waterer effectively.
How the Roll-Away Ball Waterer Works
Cattle push the floating ball aside to access drinking water. Afterward, it returns to cover the opening, helping reduce exposure to cold air, light and debris. The ball is not the refill valve; a separate valve assembly maintains water level as animals drink. A removable dome offers access to the valve for inspection, while the sealed, sloped bottom is designed to make cleaning easier.
Installation and Freeze Protection
Miraco's energy-free design depends on an appropriately installed underground water supply below the local frost line and a compatible insulated heat tube or heat well. Regular livestock visits replace water with incoming ground-temperature water. Low animal usage, inadequate pipe depth or prolonged extreme cold can allow freezing even in an insulated waterer.
- Water source: Verify pressure and flow rate for the herd and available supply.
- Buried supply line: Follow Miraco's current installation instructions and local frost-depth requirements.
- Anchoring: Mount the waterer on the specified base using suitable hardware; Miraco lists stainless-steel anchor bolts with its MiraFount models.
- Maintenance: Check the refill valve, ball closure, water level and drinking opening regularly, especially in freezing weather.
- Low-use installations: Consider a compatible heated livestock waterer if water turnover is insufficient for energy-free operation.
Choosing the Right One-Hole MiraFount
The 30-gallon model is one option for a single drinking station. Compare it with the 15-gallon MiraFount 3330 if a different reservoir size is needed, or see two-hole MiraFount waterers when animals need more simultaneous drinking access. Select on the basis of herd use, water flow, height and available installation space—not gallons alone.
Frequently Asked Questions
Does this MiraFount require electricity?
No. Model 3345 is an energy-free waterer with no integrated heater. Correct plumbing, insulation and water turnover are necessary.
Will it stay free of ice through winter?
Not in every situation. Low animal use or incorrect installation can lead to freezing. Follow Miraco's model-specific instructions and inspect water availability daily during cold spells.
Is the floating drinking ball a valve?
No. It is a drinking-port cover. The internal refill valve regulates the reservoir's water level.
Can horses use this one-hole waterer?
Miraco's published listing for the 3345 is specifically rated for beef and dairy cattle. Confirm intended species, drinking height and manufacturer guidance before using it for horses or other animals.
