Abstract: A sanitary fitting of the type that is used to connect, in back-to-back relationship, a hot and cold water source without the necessity of crossing the pipe connections, is disclosed. The sanitary fitting includes a valve assembly which, when mounted in back-to-back relation with another sanitary fitting, the valving mechanism is arranged and constructed to reverse the flow of hot and cold water through the valve, so that the fitting can be operated in its normal mode, for example, when the handle is in the left-hand position, the hot water flows and, when the handle is in the right-hand position, cold water flows.
