A flush valve is a mechanism used to flush a toilet or urinal. The valve and associated hardware are located within the toilet tank or in the body of the urinal. Most toilets have a lever or push button activator, which is used to operate the flush valve.
Ball Valves. The small shutoff valves you find under sinks and toilets are often ball valves. The valve chamber contains a close-fitting plastic or metal ball with a hole in it, and it's closed when the hole is aligned perpendicular to the water flow. The operation of a ball-valve differs from either a gate or stop valve because you can only turn the handle through 90 degrees. The valve is open when the lever is parallel to the water flow and closed when it's perpendicular.
