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.

A fail-safe water processor for in-line installation between a source of water supply and a point of use in a water distribution system, said fail-safe water processor comprising: a housing having inlet means and outlet means adapted to be connected to a water distribution system so that water flowing through the water distribution system passes through said fail-safe water processor; replaceable mechanical filter means and replaceable adsorption means within said housing in serial fluid communication with one another and with said inlet and outlet means said mechanical filter means causing a water pressure drop in water flowing through said water distribution means between said inlet means and said replaceable adsorption means across said mechanical filter means; water metering means within said housing normally in fluid communication with said inlet means and with said replaceable adsorption means, said water metering means being actuated directly by water flowing through said fail-safe water processor regardless of the duration of flow so as to cumulatively total the quantity of water that has flowed through said water metering means to said replaceable adsorption means; shutoff valve means operatively connected to said water metering means to stop water flowing to said replaceable adsorption means after a predetermined quantity of water has passed through said water metering means, said predetermined quantity of water being generally equal to the maximum safe quantity which can safely be treated by said replaceable adsorption means; first indicator means associated with said water metering means for continuously indicating what portion of the functional life of said replaceable adsorption means has been exhausted and when said replaceable adsorption means is at the end of its functional life and should be replaced; flow interruption means operatively associated with said replaceable mechanical filter means for measuring the pressure drop of water pressure across said replaceable mechanical filter means and for interrupting water flowing through said replaceable mechanical filter means when a predetermined water pressure differential, indicating the depletion of said replaceable mechanical filter means, exists across said replaceable mechanical filter means; and second indicator means associated with said replaceable mechanical filter means and said flow interruption means for indicating when the flow interruption means has interrupted the water flowing through said replaceable mechanical filter means and said replaceable mechanical filter means should be replaced.
