ABSTRACT OF THE DISCLOSURE A method of and apparatus for making and dispensing carbonated water with a double diaphragm continuous delivery pneumatic liquid pump had s water pressure regulator on a water inlet line to the pump, a water fill line to a carbonator, a propellant exhaust line from the pump to the carbonator, a carbon dioxide line to the carbonator, and a gas pressure regulator for controlling the storage pressure in the carbonator and the exhaust back pressure in the pump propellent outlet, the exhaust back pressure in kept higher than the water pressure at the pump preventing diaphragm inversion; the method has the steps of dropping water pressure into the pump to below carbonation pressure, and maintaining the carbonation pressure on the pump diaphragm preventing inversion. A method of and apparatus for boosting water pressure using the aforesaid pump wherein the pump boosted water pressure at its maximum is equal to a pneumatic propellent pressure minus a propellent exhaust back pressure plus a water supply pressure, wherein structure connected to the pump exhaust and the pump water outlet maintains a water inlet pressure less than the exhaust back pressure preventing diaphragm inversion in the pump.
