ABSTRACT:
A flush control system, for releasing different amounts of water from the holding tank of a toilet into a discharge pipe, includes an auxiliary tank mounted in the toilet holding tank. The auxiliary tank has a volume which is less than the volume of the holding tank, and has one end wall assembly with a flapper valve communicating with the interior of the auxiliary tank and another flapper valve in a different wall communicating with the interior wall of the holding tank. A chamber is formed between the two walls in which the flapper valves are located. The bottom of this chamber has an opening which is placed over the discharge pipe opening in the bottom of the holding tank. A balancing aperture is formed through one of the other walls of the holding tank to permit water flow to take place between the auxiliary tank and the holding tank. The balancing aperture is smaller in diameter than the diameter of the openings closed by the flapper valves; so that a low volume flush is effected when the flapper valve inside the auxiliary tank is opened, and a maximum flush is effected when the flapper valve located in the wall communicating with the holding tank is opened.
