What can I do if I think my Crystal is out of gas?

Not sure if your CO2 cylinder is empty?

• Make sure the cylinder is tight enough and retighten if necessary by twisting it to the right.
• If you're still not getting enough 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.

*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.

Still not sure if your carbonating cylinder is out of gas? Check out the guide below.
