Abstract: A pressurized water container for use with a drinking water purification system includes a housing having a top opening and lower first and second valves; a sealing assembly releasably mounted on the opening of the housing; a flexible upper water chamber including a top opening in communication with the opening of the housing; a lower pressure chamber having a rigid top surface fixedly secured to an inner surface of the housing wherein pressurized air is adapted to feed into the pressure chamber through the second valve for storage; an air chamber between the water chamber and the pressure chamber; and a tube interconnecting the first valve and a bottom surface of the air chamber, the tube having a port in communication with the pressure chamber, and a hand wheel for either opening or closing the port. Replacement of the water chamber is made easy by detaching the sealing assembly.
