ABSTRACT:
A faucet includes a body and first and second independent liquid conduit systems passing through the body, for handling first and second liquids, which may be respectively pure water from a water purification system and waste water (brine) generated by reverse osmosis in the purification system. The first conduit system has lower, upper and intermediate tubular portions, the latter providing a passage between the lower and upper portions. A handle is movable between a position in which the passage is closed and a position in which the passage is open. The second conduit system is a tube which is always open and which has a liquid inlet and a liquid outlet end, the liquid inlet end being connectible to the waste water (brine) line and the liquid, with the liquid outlet end spaced above and providing a gap with the maximum level of liquid in a sink.
