How do I know if my gas cylinder is empty?

There are some tests you can try to help determine if your CO2 cylinder is out of gas:

• Make sure the carbonating cylinder is tight enough and retighten it if necessary by twisting the cylinder to the right.
• If you're still not getting bubbles and if you don't hear a sputtering sound when you press the carbonating button*, you may be out of gas.

You can get a new cylinder through our online exchange program or a participating retail location.

Pro-tip: SodaStream recommends having at least 3 cylinders on hand, so you’ll always have bubbles and so you can exchange 2 at a time, taking advantage of the reduced shipping charge.

*In 2020, we upgraded the Aqua Fizz Sparkling Water Maker with a new, silent valve. In these Sparkling Water Makers, it is normal to not hear a sputtering sound and is not an indication of the amount of CO2 left in the cylinder.
