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.
