A valve leak detecting method includes a started pressure setting step for opening and closing valves individually to set a pressure in a pipe, a first threshold value evaluating step for closing the valves, after the pressure being set to no less than the threshold value, and evaluating whether the pressure, after a specific time interval has elapsed, is at least threshold value, a second valve normalcy evaluating step for evaluating that one of the valves is operating properly or faultily if the pressure is at least or less than the threshold value, respectively, a second threshold value evaluating step for closing the valves and evaluating whether the pressure is less than the threshold value after a specific time interval has elapsed, and a first valve normalcy evaluating step for evaluating whether the valve is operating properly depending on the pressure being less or no less than the threshold value. |
