Disclosed is a water pressure booster apparatus which can be employed for the dispensing of beverages. The booster can be combined as a carbonator and water pressure booster apparatus for holding both carbonated and non-carbonated water at elevated pressures, for the dispensing of carbonated and non-carbonated beverages. The apparatus has a tank including a tank chamber with a booster chamber therein. The two chambers are separated by a flexible membrane such that the elevated pressure is essentially the same in the two chambers. The booster chamber is removable through an access port in the tank. A valve provides inlet water to the tank chamber and the booster chamber. The location of the membrane controls the valve between charging of the two chambers. The valve is a spool valve with one end coupled to the membrane. The quantities of water in the two chambers controls activation of a pump which provides charging water to the chambers.
