A method and apparatus for removing and dispensing liquid from a receptacle. The apparatus includes a pump housing having a cylindrical fluid chamber, a coil spring within the fluid chamber, a coil spring within the fluid chamber to bias a piston which slidably traverses the inside wall of the fluid chamber, and an actuator button supported by the top of the piston. A bottom plug with a plug valve port, a plug intake port, a plug vent port, a plug shoulder, and a conduit boss engages the bottom of the pump housing. A tube connects to the boss to extend into the liquid within the receptacle. A cylindrical skirt rotatably lodges between the bottom of the pump housing and the plug shoulder for application to the neck of the receptacle. A diaphragm is interposed between the bottom of the pump housing and the bottom plug. The process includes pushing repeatedly downward the actuator button to draw liquid into the fluid chamber until the same is substantially full. The process additionally includes continuing to push downward the actuator button after the fluid chamber has become substantially full to bulge the diaphragm and allow the passage of liquid from the fluid chamber into the atmosphere.
