PROBLEM TO BE SOLVED: To cope with the occurrence of abnormality to a water supply device by detecting whether solenoid on-off valves for changing water flow to a plurality of branch channels are normally operated, without depending on a flow sensor or the like provided in each branch channel, and to simplify device constitution therefor to reduce cost required for the water supply device. SOLUTION: This water supply device 10 comprises the first and second branch channels 12A, 12B; the solenoid on-off valves 16A, 16B for opening/ closing the respective channels 12A, 12B; a generator 18 performing power generating operation according to the water flow of the respective channels 12A, 12B to supply power to the solenoid on-off valves 16A, 16B; and a controller for controlling the operation of the solenoid on-off valves 16A, 16B. The state of the solenoid on-off valves 16A, 16B is grasped by the controller 24 on the basis of the power generation operating state of the generator 18.
