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.

You can test the weight of your cylinder, grab some kitchen scales and if your cylinder weighs less than 750 grams it is empty and it’s time to change it . 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 website or exchange it at a participating retail location.

*In 2020, we upgraded the Crystal 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.
