How do I know if the cylinder is empty?

There are a number of indications that show your cylinder is empty:

• When you press the carbonating button you will not see any gas going into your bottle of water
• Even after repeated presses the water is not carbonated
• The carbonating button may stay down
• The cylinder splutters, showing you have run out of CO2

Please note: Keep a spare so you always have a cylinder ready to pop into your Sparkling Water Maker while you exchange your empty cylinders.
