Abstract

A water treatment or processor device for household use or commercial use (for example, in a restaurant) is provided with fail-safe features in accordance with this invention to shut the treatment device "off" when an element thereof has become ineffective, such as the saturation of an adsorption element or the clogging of a filter element. Once the device is turned "off", it cannot be restarted until the depleted element has been replaced.
