How do I know if my gas cylinder is empty?

Not getting enough bubbles with your Sparkling Water Maker? We can help.

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. Get your back-up CO2 cylinder here.

*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.
