A toilet reservoir water dumping valve for sealing the reservoir's water outlet by hydraulic pressure and for controlling the water volume to be flushed. The dumping valve is situated in the toilet reservoir at the water outlet to the toilet bowl, the dumping valve comprising a membrane housing, and a rod connected to a flush valve. In a first position, when the flush lever is in OFF position, the membrane disconnects communication between the supply line and the reservoir. Simultaneously, the rod is pressed by hydraulic pressure, tightly pushing a flush valve against the reservoir exit. In a second position, when the water is flushed, the membrane opens communication between the supply line and the reservoir, reducing the pressure on the rod, such that the rod pulls the flush valve away from the reservoir outlet, permitting water to be flushed down the toilet bowl.
