Little Giant Trough-O-Matic Aluminum Housing

Little Giant Trough-O-Matic Aluminum Housing

The Little Giant Trough-O-Matic with aluminum housing provides automatic water level control for most plastic and metal stock tanks, troughs, barrels, and pans. It flows up to 245 gallons per hour and operates between 20 and 50 psi. Best for metal or rugged plastic troughs in busy barns, this model emphasizes long-term durability and steady performance in harsh farm environments. Use this when your system prioritizes durability, a metal housing, and quick up-time after maintenance. A potential limitation is the aluminum housing’s conductance of heat, which can affect performance in very extreme temperatures if not installed away from direct sun.

This version uses a high-grade polystyrene housing, making it lighter and easier to handle. It still provides reliable automatic water level control for a wide range of stock tanks and troughs, with flow up to 245 gph and operation between 20 and 50 psi. Best for lighter-duty installations or setups where weight reduction matters. Choose this if you’re prioritizing portability and ease of mounting, but keep in mind it may be less impact-resistant than metal options in heavy-use areas.

The Threlaco set includes two float valves with mounting screws, designed to connect to 3/4 inch hoses and hang the valve and bracket securely on the tank. It provides a flow rate up to 245 gallons per hour and operates from 20 to 50 psi. Best for farms needing a cost-effective, multi-valve solution for larger trough areas or multi-tank systems. A limitation is the requirement to level the valve during installation to avoid leaks or inconsistent performance.

A caveat is that some installations may require precise leveling and careful hose routing to prevent leaks or sticking floats in heavy frost conditions.

Buying Guide: How to Choose the Right Farm Tank Float Valve

  • Flow rate and pressure: Look for valves that handle up to 245 gph and operate within 20–50 psi for most livestock setups. Higher flow helps quickly refill large troughs, but ensure your water source can sustain it.
  • Housing material: Aluminum housings offer durability in rough barn environments; plastic housings reduce weight and may satisfy lighter-duty applications. Choose based on climate, exposure, and installation location.
  • Thread and hose compatibility: Most valves use standard 3/4″ NPT or GHT hose connections. Confirm your hose size and include adapters if needed to ensure a tight seal and reliable shutoff.
  • Mounting and installation: Some kits include screws and brackets, others require separate hardware. Level the valve during installation to avoid leaks and uneven water levels.
  • Kit versus single valve: If you manage multiple tanks, a 2-pack or kit with mounting hardware simplifies deployment and ensures consistent performance across stations.
  • Durability and maintenance: Consider how easy it is to replace seals or the valve cartridge. Metal housings generally endure more wear, while plastic housings are lighter and easier to handle.

FAQ

  • Can these valves work with both plastic and metal tanks? Yes, most models are designed to fit a wide range of stock tanks, troughs, and barrels.
  • What is the typical installation height? Install so the float remains freely movable and the valve sits level with the tank’s water surface to ensure accurate shutoff.
  • Will these valves prevent overflow in hot weather? They regulate water level automatically, reducing overflow risk, but ensure your water source pressure remains steady.
  • Do these include installation hardware? Some kits include mounting screws and brackets; others require separate purchases. Check product details for included parts.
  • Is a 3/4″ hose the standard connection? Most are designed for standard 3/4″ hose connections; verify your hose type and consider adapters if needed.
  • Do I need an electrician or specialized tools? No specialized tools are typically required; basic hand tools and a level are usually sufficient.
