ABSTRACT:
A system for treating a portion of water passing through a pressurized water conduit. The system comprises water treatment means such as a reverse osmosis module. An upstream branch line communicates between the pressurized water conduit and the inlet of the water treatment means. Another branch line is provided for connection with pressurized water conduit at a location downstream from the upstream branch line, and communicating with a water outlet of the treatment means. A flow restrictor is provided, positioned in the pressurized water conduit between the conduit connection locations of the respective branch lines. Thus, water can flow through the upstream branch line from the conduit to the water treatment means, and water can flow from the treatment means through the other downstream branch line back to the conduit when water is flowing through the pressurized water conduit.
