Abstract: A multi-operation discharge control device is provided, the device includes a lower housing having a water inlet and outlet, a valve set slidably and axially disposed in the upper portion of the lower housing, a manual operation system slidably and transversely disposed into a lateral extension opposite to the water inlet of the lower housing, an upper housing axially connected to the lower housing including an automatic operation system therein. The automatic operation system contains an electromagnetic valve and an IC plate. Thereby the valve set is selectively actuated manually or automatically to move upward to define a water passage in the lower housing permitting the water to flow from the water inlet to the water outlet of the housing.
