Abstract
A water quality monitor receives water that has passed through a water softener treatment tank. The monitor contains a sample of ion exchange resin that is exposed to the water and which shrinks in volume when the water quality deteriorates to the point where it is no longer being softened. Shrinking of the resin sample signals that corrective action should be taken, such as regenerating the softener. Signaling may be a visual or audible signal or it may involve closing a valve preventing the flow of service water to one or more points of use, or restricting the flow to the extent that the restricted flow constitutes a signal to the user. The sample ion exchange resin is contained in a replaceable cartridge that can be inserted into the monitor and replaced after the monitor has functioned to signal deteriorating quality.
