Stop Wasting Water—This Does It for You

Tired of overflows, forgotten faucets, and skyrocketing water bills? This self-regulating float valve takes over. It monitors tank levels in real time and cuts off flow the instant your container is full—then restarts when levels drop. No wiring, no batteries, just mechanical precision that works in pools, livestock troughs, sinks, toilets, and cisterns. Built from corrosion-resistant plastic and PA66, it screws onto standard ½ in, ¾ in, or 1 in threaded connections and delivers high-volume fill without rust or wear. Install it once; it runs itself forever.

Why You Need This

  • Cuts Water Waste: Shuts off automatically when the reservoir reaches capacity—preventing spills and runaway usage.
  • Zero Power Required: Purely mechanical float design means no electricity, no batteries, and no moving parts that fail.
  • Broad Compatibility: Fits pools, stock tanks, irrigation systems, water heaters, toilet cisterns, and any threaded inlet from ½ to 1 inch.
  • Tool-Free Setup: Hand-tighten onto your faucet or inlet pipe—no plumbing expertise, no wrenches, no hassle.
  • Rust-Proof Construction: Durable PA66 composite resists corrosion, UV damage, and temperature swings, indoors or out.
  • High Flow Rate: Wide valve opening ensures fast fills for large tanks without choking the supply line.

Built to Last, Easy to Live With

Whether you're refilling a backyard fountain or managing livestock water, this valve stays out of sight and out of mind—doing its job day after day without supervision. The compact footprint fits tight spaces, the lightweight body won't stress aging pipes, and the eco-friendly materials mean safe contact with drinking water. Ships to your door with everything ready to go. We back every order with our 30-day return policy (unused items) and ship across the US at no extra charge. Questions?

When I started Thomler, I wanted one thing — to make it easy to find pieces that actually make a home feel like yours, without the markup. Every item we carry is one I'd happily put in my own home. And if it's ever not right, you've got 30 days to send it back, no stress. I'm only ever an email away.
