A faucet has a housing defining a cold water chamber, a hot water chamber, a first output chamber, a second output chamber, a first passage between the cold and hot water chambers, and a second passage between the hot water chamber and the second output chamber. A stem is disposed in the housing. First, second and third gaskets are mounted on the stem. The diameter of the first gasket is substantially identical to the diameter of the first output chamber and smaller than the diameter of the cold water chamber, the diameter of the second gasket is substantially identical to the diameter of the first passage and smaller than the diameter of the cold and hot water chambers, and the diameter of the third gasket is substantially identical to the diameter of the second passage and smaller than the diameter of the hot water chamber. In a first position, the first gasket is in the first output chamber, the second gasket is in the first passage, and the third gasket is in the second passage, isolating the chambers. In a second position, the first gasket is in the first output chamber, the second gasket is in the cold water chamber, and the third gasket is in the hot water chamber. Thus, the first output chamber is isolated and the cold and hot water chambers and the second output chamber are all in fluid communication. In a third position, the first gasket is in the cold water chamber, the second gasket is in the hot water chamber, and the third gasket is in the second output chamber. Thus, the second output chamber is isolated and the cold and hot water chambers and the first output chamber are all in fluid communication.
