With the help of this float valve, you can save the time of filling the tank regularly. The use of float valve in hydroponics is to ensure that nutrient level maintains in your reservoir from a header tank ( with back up nutrients). It works under gravity which means no pump is required. When the nutrients level drops in the main reservoir then fresh nutrients supply to the main nutrients tank under gravity. 

This float valve can even connect to the main water.
