Re: H2O



In fact the high resistively is used to signal when the filter needs
replacement. Most deionizers have a small electric bulb in series with
an AC line and two contacts in the tank. As long as the filter is
working the lamp does not light. As the filter becomes less efficient
the resistively of the water drops and the lamp begins to glow
indicating time to change the tank.
