A labor-saving push-button water valve includes a button, a valve core, a valve core spring, and a valve seat. The middle portion of the valve seat is formed with a core chamber. An outer periphery of a front end of the valve core is formed with an annular groove. When the button drives the valve core to move to the position where a water inlet hole is not communicated with a water outlet hole, an annular hydraulic chamber is formed between the valve core and the peripheral wall of the core chamber. The water valve is able to switch the opening and closing of the waterway smoothly by reducing the water pressure applied to the valve core, and reduces the wear of the valve core, and improves the service life and the airtightness of the water saving structure.
