Third faucet system with above sink purity indicator
First Claim
1. A drinking water delivery system for connection to a purification apparatus that receives water from a source and treats the water to remove an amount of unwanted substances from the water, comprising:
- faucet means adapted for connection to the purification apparatus and having means manually operable from an OFF condition to an ON condition for dispensing the treated water, including means for providing a visual or audible signal to a person when energized, a switch actuated in response to the ON condition, a pair of electrodes, and means for mounting the electrodes for contacting the treated water; and
circuit means connecting the switch, the electrodes and the signal providing means for charging the electrodes to thereby determine a level or purity of the treated water being dispensed only during the ON condition, and for thereafter energizing the signal providing means only when the treated water has a level of purity above or below a predetermined target purity level.

Abstract
A plastic faucet having built in LEDs and a pair of electrodes is mounted above a sink for dispensing water from a reverse osmosis purification apparatus installed below the sink or in another remote location. A circuit connected to the electrodes senses the purity of the water dispensed through the faucet each time the valve in the faucet is turned on and illuminates one of the LEDs to automatically indicate on-sight the level of purity to the user. Each time the user dispenses water from the third faucet a visual signal is received which either confirms to the user that the water has an acceptable level of purity or notifies the user that servicing of the purification apparatus is required. An alternate embodiment adapted for use with filtration type purification apparatus has a flow limiter in the faucet and a circuit which adds the time that the valve in the faucet is turned on. The circuit illuminates an LED in the faucet when the cumulative valve on time indicates that a predetermined amount of purified water has been dispensed and that it is time to service the purification apparatus.

9. A drinking water delivery system comprising:
-
a faucet mounted above a sink, the faucet being manually operable between a closed position and an open position; reverse osmosis purification means mounted below the sink for receiving water from a source, treating the water to remove an amount of unwanted substances from the water, and delivering the treated water to the faucet; a pair of electrodes mounted in spaced apart relationship for contacting the treated water as it flows through the faucet; means mounted above the sink for providing an illuminated signal when energized; switch means mounted in the faucet and movable between open and closed positions when the faucet is operated between its closed and open positions; and battery powered circuit means for charging the electrodes only when the faucet is in its open position and the switch means is closed, for determining a level of dissolved solids in the treated water contacted by the electrodes, and for energizing the illuminated signal providing means when the level of dissolved solids is above a predetermined acceptable concentration. - View Dependent Claims (10, 11, 12, 13)

14. A drinking water delivery system for connection to a purification apparatus that receives water from a source and treats the source to remove unwanted substances from the water, comprising:
-
faucet means adapted for connection to the purification apparatus and having means manually operable from an ON condition to an OFF condition for dispensing the treated water; means for providing a visual or audible signal when energized; a switch actuated in response to the ON condition; means for limiting the flow through the faucet means to a predetermined substantially constant flow rate under a normal operating water pressure; and circuit means connected to the switch for accumulating the amount of time that the faucet means is in its ON condition and for energizing the signal providing means after the accumulated amount of time reaches a preset maximum to thereby indicate that a predetermined volume of treated water has been dispensed through the faucet means. - View Dependent Claims (15, 16)
