Float Rises with the Water, Shuts Off When It’s Full: The buoyant float follows the water level and triggers the valve to close at a set height—reopens automatically as the level drops, so you never have to watch or wait Custom Fill Height with a Simple Pivot: Just loosen the lock nut, swing the float arm to the level you want, and tighten it down—works equally well for shallow troughs and deep storage tanks Slim Profile Fits Tight Spots Without Crowding: The compact, streamlined valve body slips into narrow tank openings, under sinks, or onto garden hose threads without blocking other fittings Seals Tight the Moment the Float Settles: The tapered closure seats firmly as the valve shuts, stopping the flow cleanly and keeping water from dribbling past the set level One Valve Handles Pools, Tanks, Troughs, and Fountains: Dependable for auto-fill on swimming pools, livestock waterers, hydroponic systems, decorative fountains, and garden reservoirs, Manufacturer: Qvorlth
