The present invention provides a sanitary automatic water leakage detection and shut-off apparatus installed between a water controlling unit and a water outgoing unit and comprising a water controller, an accumulating unit and a detecting unit; wherein the water controlling unit comprises an inlet, an outlet and a solenoid valve. The solenoid valve is a normally-open solenoid valve capable of closing the outlet to stop water from going out. The accumulating unit is mounted between the water controlling unit and the water outgoing unit and comprises an accumulating hole adjacent to a bottom thereof. The detecting unit is installed on the accumulating unit and electrically connected to the solenoid valve. The detecting unit activates the solenoid valve via an electronic communication method based on a leakage status of the accumulating unit to shut off the water outlet of the water controlling unit and to stop water supply thereof immediately.
