Abstract

The invention relates to a dual-discharge tank for toilets, including a tank, a water inlet having controlling means which are activated depending on the volume of water contained in the tank, a discharge mechanism coupled to a drainage collector, and means for actuating the discharge mechanism. The tank also includes an additional water inlet connected to a timed valve for controlling water flow, which automatically cuts off the flow of water through said inlet after a predetermined time has elapsed since the actuation thereof. The outlet of the timed valve for controlling water flow is connected to a first pipe that directs the additional water toward the drainage collector.
