Claim:
1. A storage device for a water purification system to supply filtered water in a purified water line dispensed through a tap, said storage device comprising: a housing in which is disposed a flexible bladder for retaining filtered water and a pumping zone formed between said bladder and said housing; and a hydroautomatic unit including a pressure-sensitive, normally open pumping valve having a pumping valve controlled chamber and a pumping valve controlling chamber, and a pressure-sensitive, normally closed drainage valve having a drainage valve controlled chamber and a drainage valve controlling chamber, said normally closed drainage valve controlled chamber having an input in flow communication with said pumping zone and an output to drainage, said pumping valve controlling chamber and said drainage valve controlling chamber operating independently and each controlling chamber being in communication with said filtered water in said purified water line, wherein when said tap is closed, said filtered water in said purified water line flows into said bladder and supply water in said pumping zone flows out through said normally closed drainage valve controlled chamber to drainage, and wherein when said tap is open, said drainage valve controlled chamber closes and said pumping valve controlled chamber opens permitting supply water to flow though said open pumping valve controlled chamber directly into said pumping zone, thus forcing filtered water in said bladder to flow out to said purified water line and out through said open tap.
