BALL COCK

A ballcock (also balltap or fill valve) is a mechanism for filling water tanks, such as those found in flush toilets, while avoiding overflow. It was invented by Thomas Crapper.It consists of a valve connected to a float by means of a lever, mounted near the top of the tank. The valve is connected to the incoming water supply, and is opened and closed by the lever which has the float mounted on the end. When the water level has risen to a preset fill line, the float forces the lever to close the valve and shut off the water flow.
