ABSTRACT:
A water purification system and method. A closed water recirculation loop supplied at one point by a water inlet with water to be purified, and having at least one outlet point of use of the purified water. Also included is a pump and a water purifier on the loop respectively downstream of the inlet point and upstream of the at least one outlet point, in the water flow direction. The system includes two independent valves, including a first valve on the loop upstream of the pump and a second valve upstream of the at least one point of use outlet point. The first and second valves are selectively opened and closed to recirculate all the water treated by the purifier.
