This patent describes a bypass/diverter valve for controlling the flow of fluid from a source to a fluid treatment device such as a water softener. The valve includes a valve housing defining a circular chamber having a cylindrical wall into which three spaced ports open into. Two of the ports form inlet/outlet ports communicating with connecting conduits. The third port forms an intermediate port that communicates with the input to the water softener. The valve housing also defines a second intermediate port communicating with the output of the water softener and which communicates with the valve chamber through a passive arrangement. A plug-like valving member is rotatable within the chamber and includes a recess which together with the chamber wall defines a passage for selectively communicating one of the inlet/outlet ports with the first intermediate port while concurrently communicating the other inlet/outlet port with the second intermediate port or alternately for communicating the first inlet/outlet port with the first intermediate port.
