An American Standard toilet actuator works like the flapper valves in modern gravity-flush toilets. … The actuator lifts up, opening the drain hole in the bottom of the toilet, letting the water rush into the bowl and flush the waste down the drain.

What does a flush valve do?

The flush valve, located in the middle of the toilet tank, includes the overflow tube, the hole where water enters the bowl when the toilet is flushed and the rubber tank ball or flapper that covers the hole when the tank is full. A broken flush valve prevents your toilet tank from forming a seal to hold water.
