A ballcock is the fill valve that controls the flow of water into a toilet tank. It consists of a float attached to a lever arm, which rises and falls with the water level in the tank. As the float rises, it shuts off the water supply once the tank reaches the desired level. Ballcocks are essential for maintaining the correct water level in the toilet tank, ensuring a proper flush and preventing overflow. They come in various designs, including traditional brass models and more modern plastic versions. Over time, ballcocks may require adjustments or replacement due to wear, mineral buildup, or faulty seals, all of which can lead to water waste or inefficient flushing.
