Installation & Usage Tips

For best results, wrap the 1/2" NPT threads with PTFE (plumber's) tape before threading into your supply line fitting. Hand-tighten first, then snug with a wrench — avoid overtightening brass fittings. Adjust the float arm angle to set your desired water level, and the valve will handle the rest automatically.

Frequently Asked Questions

Q: What pipe thread size does this float valve use?

A: This float valve uses a standard 1/2-inch NPT (National Pipe Thread) connection, making it compatible with the vast majority of standard plumbing fittings and water supply lines used in ponds, tanks, and troughs.

Q: Can I adjust the water level this float valve maintains?

A: Yes! The float arm rotates over 180 degrees, giving you a wide range of adjustment. Simply reposition the arm to raise or lower the cutoff point to match your desired water level — no tools or electricity needed.

Q: Is this float valve suitable for aquariums and fish tanks?

A: Absolutely. The valve is constructed from rust-resistant plastic and brass with no high-concern chemicals, making it safe and reliable for use in aquariums, fish tanks, ponds, and livestock water troughs alike.

Q: Does this valve require electricity or a pump to operate?

A: No — the LEENKEA float valve is entirely mechanical. It uses the buoyancy of the float ball to open and close the water inlet automatically. No batteries, power outlet, or pump are required.

Q: How do I ensure a leak-free installation?

A: The package includes a rubber gasket that creates a watertight seal at the connection point. For added security, wrap the NPT threads with PTFE tape before fitting and hand-tighten, then give it a firm (not excessive) final turn with a wrench.
