Abstract
A single valve and associated conduits for so operating a reverse osmosis assembly that includes a reverse osmosis cartridge, a reservoir that has a movable barrier therein that sub-divides the interior into first and second confined spaces of variable volume, and a manually operated purified water dispensing valve, so that as the first confined space approaches a filled condition with purified water, the single valve throttles the flow of pressurized feed water to the cartridge to minimize the use of feed water in the operation thereof and when the second confined space approaches a filled condition with reject water the single valve stops the flow of pressurized feed water to protect the reservoir from damage due to high pressure that may be present in the feed water source.
