A method of batch carbonating water and then dispensing in a carbonator using carbon dioxide at a supply pressure, such as to result in fast and efficient carbonating and unrestricted dispensing comprising: (a) disposing a slow feed valve at the inlet of said carbonator, said slow feed valve having a small orifice and larger orifice; (b) causing a flow of the carbon dioxide through the water being carbonated at a controlled rate by causing carbon dioxide gas to flow in a controlled manner through said small orifice until a predetermined pressure less than the supply pressure is reached in the carbonator and, upon reaching said predetermined pressure effectively terminating flow through said small orifice; and (c) after said predetermined pressure is reached then allowing gas to flow through said larger orifice. Apparatus for controlling flow of gas in a batch carbonator comprising: (a) an inlet slow feed valve disposed at the inlet to said carbonator, said inlet slow feed valve containing a small orifice and which will limit flow of gas through water in said carbonator and a valve responsive to the pressure within said carbonator for controlling the flow through said orifice and an orifice of larger size, said valve adapted to maintain said orifice of larger size closed until said predetermined pressure is reached whereupon said valve opens to permit flow through said larger orifice; and (b) a check valve in said slow feed valve to prevent backflow therethrough.
