How can I tell if my Source 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. Do not use tools.
• 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 at a participating retail location.
