A semi-flush valve mechanism in a toilet tank is provided with a two way flush operating handle. If the handle is pressed downward the toilet tank is flushed fully in the conventional way. If the handle is pressed upwardly the toilet tank is only half emptied in a semi-flush. A pivotally extended vane on a tilted valve assembly will receive a water stream from a refill tube to sooner help restore the toilet tank valve assembly to its closed upright position causing the semi-flush.
