Automatic Water Level Control Valve, Toilet Float Valve for Water Tank, Pool and Pond
- Spills stop on their own: the flow shuts off by itself once the preferred water level is reached
- No standing guard by the tank: it fills only when necessary, without electricity or constant oversight
- Sun and weather will not wear it down: the UV-stable, weather-resistant body keeps working outdoors
- Tight spots are no problem: the space-saving design installs straightforwardly in confined areas
- One valve for every container: it suits everything from animal drinking troughs to swimming pools
A tank that fills while you are busy elsewhere should never turn into a puddle. This float valve for a water tank lets containers fill only when necessary, and the moment the preferred level is reached the flow automatically ceases, so there are no more spills — and it needs no electricity and no constant oversight to do it.

As the water level declines, the valve adjusts itself automatically, in water tanks, swimming pools, ponds, drinking troughs, solar systems and toilets. Its ABS plastic body is UV-resistant and safe for food, and it comes in 0.5" (1.3 cm), 0.7" (1.8 cm) and 1" (2.5 cm) sizes with an upper water inlet.
