PROBLEM TO BE SOLVED: To inexpensively perform inspection with easily-operable and simple facilities, and moreover surely detect the presence of a water leakage spot of a dispenser for drinks. SOLUTION: The drink dispenser (1) is provided with a bottle loading section (3) at the top surface of the main body (2) of the dispenser, a drink storage section (6) inside the main body (2) is made to communicate with the loading section (3), and water faucets on the external surface of the main body (2) and the storage section (6) are connected to each other with pipes (7). With the water faucets closed, a sealing member (17) is fitted into a liquidtight state to a loading start position (S) of the loading section (3). Following this, press fit of the sealing member (17) to a measuring position (T) lower than the start position (S) of the sealing is performed while maintaining the liquidtight state. A pressure gauge (19) is connected to an air communication passage (18) formed in the sealing member (17) by penetration, and changes over time in the inside atmospheric pressure of the storage section (6) increased by the press fitting are measured.
