Abstract
Abstract A toilet tank flush valve which can be operted to provide a full or partial flush of the fluid contents of the tank. An auxiliary operating arm is provided so as to cooperate with the conventional valve actuating mechanism and at the same time not interfere with the operation of such mechanism. The operating arm cooperates with the conventional mechanism so that upon actuation of said arm the mechanism effects only a partial opening of the flush valve from a closed position.
