Abstract: A plumbing fixture includes a tubular waterway and an enclosing cover. There is a space between the cover and waterway. In the method of manufacturing such plumbing fixture, a foam material consisting of a base and a catalyst therefor is positioned within the space between the cover and the waterway, with the foam material growing in the space until the space is completely filled and the waterway is secured to the cover. The foam material not only is the securing agent for the waterway and cover, but provides temperature, noise and vibration isolation therebetween.

Abstract: A valve (10) for a water temperature control system having a heat exchanger (C), a tank (T), and a pump (P) for circulating heat transfer fluid through a supply line (11, 12, 13) from the tank to the heat exchanger and through a return line (14, 15) from the heat exchanger to the tank including a valve housing (20) interposed in both the supply line and the return line having supply inlet and supply outlet connections (24, 25), having return inlet and return outlet connections (26, 28), and having first and second drain connections (29), a valve element (45) associated with the valve housing having a first position for normally circulating the heat transfer fluid from the supply inlet connection to the supply outlet connection and from the return inlet connection to the return outlet connection and having a second position discontinuing circulation through the supply inlet connection and the return outlet connection and connecting the supply outlet connection to the first drain connection and the return outle
