How do I know when my CO₂ cylinders are empty and ready for exchange?Updated 21 hours ago

You’ll know your CO₂ cylinder is empty when the water no longer becomes bubbly during the usual carbonation process.

You can also check by weight — an empty cylinder weighs around 750-800g.

Before exchanging your cylinder or placing it in the return box, you can confirm it’s completely empty by gently pressing the center pin with a spoon. This will release any remaining CO₂ safely before shipping.
