Abstract

A reverse osmosis system for purifying water. The system comprises a reverse osmosis module comprising a housing within which a membrane is disposed, the housing provided with an inlet and two outlets, a first outlet for dispensing water that had passed through the membrane and a second outlet for emitting water that had not passed the membrane to be rejected into a drain. A collecting tank comprises first and second compartments, separated by a diaphragm, the first compartment for containing water fed from a feed-in line having a first inlet/outlet opening and the second compartment for containing purified water having a second inlet/outlet opening. A dual purpose valve is adapted to be switched between two positions, an open position facilitating filling of the first compartment with water, to thereby force purified water from the second compartment, and simultaneously opening a faucet dispensing purified water to a spout, and a closed position facilitating filling of the second compartment with purified water, forcing emission of water into the drain, and simultaneously closing the faucet to the spout.
