A method of and apparatus for making and dispensing carbonated water with a double diaphragm continuous delivery pneumatic liquid pump has a water pressure regulator on a water inlet line to the pump, a water fill line to a carbonator, a propellent 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 is 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.

A method of boosting water pressure and supplying quantities of water at the boosted pressure with a double diaphragm continuous delivery pneumatically powered liquid pump, comprising the steps of: providing and controlling the water supply pressure (Pws) water boosted pressure (Pwb), pneumatic propellent pressure (Pp), and the propellent exhaust back pressure (Pe), according to the algorithm Pwbmax=Pp-Pe+Pws, by maintaining Pe greater than Pws with control means connected to a propellent gas exhaust from the pump and to a water supply line into the pump, for controlling the valves of Pe and Pws respectively, and thereby preventing inversion of the diaphragms in the pump while reciprocating the diaphragm in the pump and pumping water at up to Pwbmax . A pneumatically powered water pressure boosting apparatus (a) operatively defined by the algorithm Pwbmax=Pp-Pe+Pws, wherein: Pwb=boosted water pressure, out of the pump, Pp=pneumatic propellent pressure into the pump, Pe=propellent exhaust back pressure at the pump, Pws=water supply pressure at the pump; and having (b) a double diaphragm continuous delivery pneumatically powered liquid pump having a liquid inlet connectible to the water supply pressure, a liquid outlet for water at the boosted pressure, a gas inlet connectible to the propellent pressure, and a gas outlet subjectable to said exhaust back pressure; (c) means connected to said gas outlet and said liquid inlet for maintaining Pe greater than Pws.
