Abstract
A water treatment and storage system includes a reverse osmosis treatment unit having an untreated water input line, a treated water output line and a bleed water output line. An expandable container, compressed by a spring arrangement, is provided for storing treated water. A container valve, connecting the reverse osmosis treatment unit and the expandable container, terminates the flow of treated water to the container when a predetermined quantity of water has been accumulated therein. The container valve further includes a bleed valve arrangement connecting the bleed water output line and a drain line. The bleed valve arrangement terminates the flow of bleed water to the drain line after the container has accumulated the predetermined quantity of treated water.
