1. A multi-valve water treatment system comprising:
a motor having an output shaft;
a driven shaft fixed to the output shaft such that the driven shaft is driven by the motor when the motor is activated, the driven shaft having a cam disposed at an axial position along the driven shaft; and
a valve assembly including:
a valve actuator urged into engagement with the driven shaft at the axial position, such that the valve actuator is moved axially upon engagement with the cam, the valve actuator comprising an aperture configured to receive the driven shaft;
a fluid flow housing having a fluid outlet and at least one fluid inlet selectively sealingly engaged by the valve actuator to define a valve configured to selectively allow a flow of fluid from the at least one fluid inlet toward the fluid outlet depending on the relative positions of the driven shaft and the valve actuator; and
a diaphragm sealingly isolating the fluid inlet of the fluid flow housing from the valve actuator;
wherein the diaphragm is fixedly coupled to the valve actuator such that diaphragm remains fixed to the valve actuator over all operating positions of the driven shaft.
