How do I know if my CO2 cylinder is empty?

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

  • 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.
