A system for providing different levels of carbonated water on demand, the system comprising:
- a pressurized chamber to hold at least one of water and carbonated water;
- a gas canister to dispense carbon dioxide (CO2) into said pressurized chamber;
- a water pump to cycle said at least one of water and carbonated water in and out of said pressurized chamber;
- a controller to control said dispensing of said CO2 according to one of a plurality of pre-defined levels of carbonation, wherein said controller switches off said water pump and stops the flow of CO2 from said gas canister once a required level of carbonation has been obtained;
- an activator to activate said water pump according to pre-defined times to meet said demand at one of said pre-defined levels of carbonation;
- and
- a valve to vent excess gas from said pressurized chamber after carbonation.
