Abstract
A flow channel switching system (') including: a first on-off valve () which is disposed between a merging portion () and a branching portion () and in a raw water path (); a second on-off valve () which is disposed in an outward path for raw water (); and a sensor () that measures a state of water flowing through the raw water path, in which control is performed so as to open the second on-off valve and close the first on-off valve if a signal indicating that water is flowing in the raw water path is received from the sensor, then a signal indicating that no water is flowing in the raw water path is received, and then, within a predetermined time period, a signal indicating that water is flowing again in the raw water path is received.
