Abstract:
1. A reverse osmosis water purification system, comprising: a reverse osmosis cartridge having a tap water inflow port for receiving a tap water inflow from a water supply system to produce a supply of relatively purified water discharged from said cartridge via a purified water outflow port, and a supply of brine having impurities concentrated therein and discharged from said cartridge via a brine outflow port; a storage reservoir coupled to said purified water outflow port for receiving and storing a predetermined volume of the produced purified water for on-demand dispensing; a purified water dispense faucet coupled to at least one of said purified water outflow port and to said storage reservoir for dispensing the produced purified water; a recycle pump coupled to said brine outflow port for recycling the produced brine to the water supply; and a control valve coupling said recycle pump to said water supply system through alternate flow paths such that brine is selectively recycled to flow through the tap water inflow.
