Common FAQs about refilling CO2

Can you refill CO2 canisters yourself?

While technically it's possible to refill CO2 canisters yourself, it's not recommended for safety and consistency reasons. Dealing with compressed gases can be dangerous if not done properly and can lead to inconsistent carbonation levels in your drinks.

The best and safest way to ensure a steady supply of CO2 for your soda maker is through a refill service like the Soda Sense CO2 Refill Club for your SodaStream CO2 exchange.

This ensures not only safety and convenience but also the high-quality carbonation you love in your homemade beverages.

How do I know if my CO2 cylinder is empty?

To ensure that you are using your CO2 canister to its fullest potential, there are some methods you can use to accurately determine if it is completely empty before you return it.

Be sure to follow all necessary safety measures when using these techniques:

1. Weight Check: Compare the weight of two cylinders; if one feels lighter, it’s likely empty. Use a kitchen scale for accuracy.
2. Machine Performance: If your drinks aren’t as fizzy, your CO2 is running out. When bubbles stop, it’s time to replace the cylinder.
3. Spoon Test: Depress the center pin with a spoon to release remaining CO2. If nothing escapes, the cylinder is empty and safe to store or return. Secure it with the cap before shipping.

How many pumps of gas does a soda machine use?

One CO2 gas canister, used for making soda, has a volume of 60L and can produce 60 bottles of soda. It is recommended to use 2 pumps for carbonating, and 1 pump is equal to 0.5L.

Therefore, if you divide 60L by 0.5L per pump, you can use the canister for 120 pumps before needing to replace it.

Do Soda Sense canisters work with SodaStream machines?

Yes! They absolutely do. Using a Soda Sense Threaded 60L CO2 canister in your SodaStream is far more convenient and cost-effective than exchanging directly with your Soda Machine provider.

Double-check that your SodaStream takes threaded 60L CO2 canisters, although, if your machine takes a snap-in canister, you can also exchange it through the Soda Sense Refill Club.
