A purified water storage system for a reverse osmosis purification unit has a container containing an interior chamber defined in part by a flexible wall member, such as a bladder or diaphragm, for receiving and containing purified water. A second chamber for containing pressurized air exists on the opposite side of the flexible wall member. The second chamber is at least 75%, preferably 80%, and still more preferably 100% of the maximum volume of the water-containing chamber.
