Water Trough Float Valve for Livestock

This universal float valve is designed to automatically control water levels in troughs, tanks, and reservoirs used for cattle, horses, goats, and more. It supports standard 3/4 inch NPT hose connections and delivers up to 245 gallons per hour, operating under 20 to 50 psi. A straightforward assembly makes it suitable for farms where water management and preventing waste are priorities. The unit aims to reduce manual monitoring by ensuring a steady water supply during day and night hours.
API Automatic Waterer Deicer

The API Automatic Waterer Deicer is thermostatically controlled with overheating protection to prevent water from getting too hot. It is designed to be safe for use in plastic water tanks and features a cooling profile that maintains a lower operating temperature. This deicer helps keep liquid water from freezing in cold environments, reducing the risk of water blockage and ensuring livestock have access to liquid water during winter months.
Little Giant Automatic Livestock Waterer

This automatic waterer dispenses fresh water based on the basin’s water level. Its galvanized steel body is coated with a nontoxic epoxy finish, offering corrosion resistance. It’s designed to connect easily to standard hose or pipe sizes (1/2 inch), making it a practical choice for barns seeking a simple, reliable water dispensing system for horses, cattle, or hogs. Regular maintenance keeps the unit functioning effectively without frequent attention.

The kit supports 1/2 inch to 3/4 inch threaded connections, making it suitable for barrels and small tanks used to hydrate hogs efficiently.
Buying Guide: Key Purchase Considerations
Watering systems for hogs and livestock vary in mechanism, installation requirements, and maintenance needs. Consider the following when selecting a setup:
- Durability and material: Aluminum housings and galvanized steel offer corrosion resistance in humid farm environments; stainless steel nipples resist rust and cracking.
- Water flow and pressure: Ensure compatibility with your water source; most valves and float systems perform well within 20–50 psi.
- Automation vs. manual: Float valves provide automatic replenishment, while nipple drinkers require animals to trigger hydration. Choose based on herd size and labor capacity.
- Installation compatibility: Look for standard fittings (1/2″ or 3/4″ NPT) and common tank shapes to simplify mounting and maintenance.
- Winter performance: Deicers are valuable in freezing climates but should be paired with well-insulated tanks or sheltered setups.
- Maintenance and cleanliness: Regular inspection prevents leaks and ensures clean water; units with easy disassembly benefit routine cleaning.
- Compatibility with existing tanks: Verify that float valves and deicers fit the tank materials (plastic, metal, or composite) in your stock troughs.
When choosing, assess the livestock type (hogs require robust, durable fixtures), the climate (winter readiness), and the property layout (ease of access for filling and cleaning). Testing multiple configurations over a season helps determine which system provides consistent water access with minimal maintenance, aligning with farm operations and animal welfare goals.
