A faucet waterway assembly is provided having a housing comprising a first valve for controlling flow of hot water and second valve for controlling flow of cold water. A first handle interface is configured to attach to a first handle for controlling the first valve and to rotate about a first axis of rotation that is spaced apart from the housing. A first mechanical transmission device is provided coupled to the first handle interface and coupled to the first valve, wherein rotation of the first handle interface about the first axis of rotation causes the mechanical transmission device to cause rotation of the first valve about a second axis of rotation to control the flow of hot water. A second handle interface for controlling the second valve is provided, along with a corresponding second mechanical transmission device for coupling the second handle interface to the second valve.

An electromagnetic valve manifold includes an electromagnetic valve including an output port, a manifold base including an output passage, and a spacer arranged between the manifold base and the electromagnetic valve. The spacer includes a spacer block including a shaft hole and a manual shaft accommodated in the shaft hole. The spacer block includes an output connecting passage that is connected to the shaft hole and connects the output passage and the output port to each other. The manual shaft is configured to be manually operated to be switched between a first switching position, in which the manual shaft allows for connection between the output passage and the output port through the output connecting passage, and a second switching position, in which the manual shaft blocks the connection between the output passage and the output port through the output connecting passage.

A channel selecting valve has: a main body, two control cores, two stopping members, and two handles. The main body has an intake opening on one side, and a first outlet opening, a second outlet opening, a third outlet opening and a fourth outlet opening on another side. The main body connects the intake opening with each outlet opening. Two openings at each end of the main body respectively accept a control core for assembly. Each control core is a hollow tube with one open end and one closed end, the open end of the control core is inserted into one of the openings of the main body. Each of the closed ends of the control cores is connected to a respective handle for switching. Both of the two control cores have a first through hole, a second through hole, a third through hole and a fourth through hole.
