A bottled water pressurization system draws purified water from a five gallon bottle by means of an electric pump, forcing the purified water into a tank containing a certain quantity of pressurized air, maintaining a level of water in the tank sufficient to produce a pressure of approximately 25 to 50 pounds per square inch. An outlet of the tank delivers pressurized water to a faucet or spigot, coffee machine, an ice make, a refrigerator, a hot and/or cold drinking water delivery unit, or other such appliance. A flexible tube is connected to the pump inlet and draws water from the bottle through an upright tube and cover assembly inserted into and over the mouth of the bottle. The upright tube extends nearly to the bottom of the bottle. A one-way valve attached to the bottom of the upright tube prevents reverse flow spillage of residual water in the upright tube when it is removed from an empty bottle and installed in a full one. A low water level sensor produces a control signal to actuate a low water level switch to disable the electric pump when the bottle is empty.

An apparatus for supplying pressurized water from an unpressurized bottle, comprising in combination: (a) a cover having a hole therein and covering an opening at the upper portion of the bottle; (b) a sealed tank containing a certain quantity of pressurized air and having an inlet/outlet opening located at the bottom of the tank and a delivery tube connected in open communication with the inlet/outlet opening for delivering pressurized water in the tank to an external utilization device, such as a faucet, or an ice maker and/or a cold drinking water delivery unit of a refrigerator; (c) a pump, having an inlet and an outlet, for pumping water from the bottle into the tank; (d) a tube connecting the outlet of the pump to the inlet/outlet opening; (e) first tubular means extending through the hole in the cover to a level near the bottom of the bottle; (f) second tubular means for connecting an upper end of the first tubular means to the inlet opening of the pump; (g) first valve means located in the bottle connected to the bottom of the first tubular means for preventing spillage of residual water from the first tubular means when it is removed from the bottle; (h) second valve means connected in series relationship with the inlet/outlet opening of the tank for preventing flow of water from the tank back into the outlet of the pump; (i) a pump motor for driving the pump; (j) pressure sensing means for sensing the pressure in the tank; (k) control means connected to the pressure sensing means for turning on the pump motor when the pressure in the tank falls below a first level and turning the pump motor off when the pressure in the tank exceeds a second level that is greater than the first level; and (1) means for producing a control signal when the level of water in the bottle falls below a selected level near the bottom of the bottle, the control means responding to the control signal by turning off the pump motor, thereby preventing the pump from running dry, whereby the pump and pump motor operate to maintain a supply of pressurized water from the bottle in the tank and a continuous supply of pressurized water is provided to the utilization device.
