PROBLEM TO BE SOLVED: To provide a water supply device capable of supplying water to a washing device of a toilet by changing over reclaimed water and city water at the same time, preferentially supplying reclaimed water and supplying water without changing any structure of the washing device of the conventional toilet. SOLUTION: The water supply device is used as a channel selector valve 32, and the channel selector valve 32 includes a reclaimed water inflow port 36, a city water inflow port 40, an outflow port 44 for flowing out of the reclaimed water or the city water to the washing device of the toilet, a water service valve 56 for opening and closing a channel 54 of the city water, a diaphragm 62 operatively connected to the water service valve 56 and closing and operating the water service valve 56 when the water supply pressure is higher than set pressure resulting from displacement by water supply pressure of the reclaimed water and a check valve 70 opened by the water supply pressure of the reclaimed water flowing from the inflow port 36 of the reclaimed water and making the reclaimed water flow into the outflow port 44.
