Flush Valves
The flush valve can use a tapered rubber float ball or a flapper ball to control the flow of water into the toilet.
Flapper balls are common on newer flush valves and are connected to the handle lift arm with a lift chain.
Toilet Tank Flapper Ball
Float balls are more common on older style flush valves and are designed to lift and drop into the valve opening. The float ball is connected to the handle lift arm by a lift wire that runs through a guide arm attached to the overflow pipe.
