Abstract
A dual flush toilet assembly including a locking mechanism that prevents over travel of a piston, thereby preventing inadvertent full flushing when only a partial flush has been selected, yet permits full flushing when so desired. Specifically, a rotatable locking mechanism that prevents the piston from moving fully upwards into the second latched position when a partial flush is desired, yet rotates to an unlocked position to permit the piston to move fully upwards into the second latched position when full flushing is desired.

1-10. (canceled)
A toilet flushing system, comprising:
- a frame;
- a piston moveable within the frame;
- a lever mounted to the frame, wherein the lever lifts the piston to a first latched position for a first flush and lifts the piston to a second latched position for a second flush;
- and
- a locking mechanism mounted to the frame, wherein the lever lifting the piston causes the locking mechanism to move between a locked position that prevents the piston from moving to the second latched position to an unlocked position that permits the piston to move to the second latched position.
The system of claim 1, wherein the second flush is a full flush, and wherein a distance travelled by the piston for the first flush is less than a distanced travelled by the piston for the second flush.
