To quickly perform ignition for a hot water supplying device by opening a bypass valve when the flow rate required for ignition for the hot water supplying device connected to a water faucet is less than the consumption flow rate for a device, and compensating for the flow rate so as to satisfy the ignition flow rate of the hot water supplying device.
When hot water supply is to be started to a device, a valve element 12e of a bypass valve 12 is turned and moved downward. The upstream side of a constant flow valve 11 is communicated with a socket 5 side, and supply water from a second valve hole 6b is supplied to the device by being divided into water to pass the constant flow valve 11 and water to pass through a bypass passage 12d from a communication hole 12a. The upper limit of the passing flow rate of the constant flow valve 11 is limited, however, the flow rate to pass the constant flow valve can be added by opening of the bypass valve 12. Therefore, ignition for a hot water supplying device is made possible before starting water supply to the device, by making the total flow rate exceed the flow rate value required for ignition for the hot water supplying device.
