Abstract
A water treatment system having an inlet for receiving water to be treated and a manifold that defines a pair of fluid streams communicating with the inlet. A valve module carried by the manifold controls the communication of water at the inlet with treatment cartridges and with a common outlet. The valve module includes a valve member that is movable between two positions such that, in one position, the valve member communicates each fluid stream with an associated cartridge and, in a second position, communicates the inlet with the common outlet and bypasses the cartridges. A remotely mounted cartridge depletion indicator is provided that includes a linkage that is magnetically coupled to a stem assembly located within a flow metering mechanism. Movement in the internal stem assembly is transferred via the magnetically coupled external linkage to a cartridge depletion indicator visible to the operator.
