How do float valves work?
Float valves work off of the same concept that your toilet works off of. When the water level of the reservoir drops, it causes the float valve to drop with it, thereby opening up the pathway for water to flow into the reservoir. When the reservoir is filled up again, the float valve rises back up with the water and closes off the pathway, thus restricting water from passing through. A watering timer is suggested to prevent unwanted floods from occurring. When your hydroponic system is running full steam ahead, the last thing you want is the float valve to drop, allowing EXCESS water into the reservoir.
