SodaStream CO₂ Refill: 5 lb Tank, Adapter & Direct Connect Options

If you use your SodaStream regularly, you may be looking for an easier and more economical way to keep CO₂ on hand. Instead of relying only on the smaller SodaStream cylinders, some users choose to use a larger 5 lb CO₂ cylinder.

There are two common ways to do this: refill your smaller SodaStream cylinder from a 5 lb CO₂ tank, or connect the 5 lb tank directly to your SodaStream.

Here’s a look at how each option works.

Option 1: Refill Your SodaStream Cylinder From a 5 lb CO₂ Tank

With this setup, a 5 lb CO₂ cylinder is used to refill your smaller SodaStream cylinder.

The larger CO₂ tank connects to the smaller SodaStream cylinder using a compatible refill adapter. Once the smaller cylinder is filled, you put it back into your SodaStream machine just as you normally would.

This option can be a good choice if you want to keep the SodaStream setup looking clean and familiar on your countertop.

Benefits include:

• Keep using your existing SodaStream cylinder

• Keep the larger 5 lb tank away from the countertop

• Have the ability to refill your smaller cylinder multiple times

• Keep an extra filled cylinder available for convenience

The main consideration is that you still need to remove and refill the smaller cylinder when it runs out.

Option 2: Connect a 5 lb CO₂ Tank Directly to Your SodaStream

The second option is to connect the larger 5 lb CO₂ cylinder directly to the SodaStream using a compatible connection and hose.

Instead of installing a small SodaStream cylinder in the machine, the 5 lb tank supplies the CO₂ directly while you use the SodaStream.

This can be convenient for people who make sparkling water frequently and want a larger CO₂ supply without repeatedly changing the smaller cylinder.

Benefits include:

• A much larger CO₂ supply

• No need to repeatedly change small cylinders

• Convenient for frequent use

• Less reliance on SodaStream cylinder exchanges

The trade-off is that the larger tank needs to be positioned near the SodaStream, and the hose and connections become part of the setup. Connections also need to be properly fitted to help prevent CO₂ leaks and wasted gas.

Which SodaStream CO₂ Setup Is Right for You?

It really comes down to how you use your SodaStream.

If you want a cleaner countertop setup and don't mind refilling the smaller cylinder, using a 5 lb tank to refill your SodaStream cylinder may be the better option.

If you use your SodaStream frequently and want the convenience of a larger CO₂ supply, connecting a 5 lb tank directly to the machine may make more sense.

Make Sure You Have the Right Adapter

SodaStream machines use different cylinder connection systems, including screw-in and Quick Connect cylinders. The adapter or connection you need will depend on the SodaStream model and cylinder you have.

Before purchasing an adapter, make sure it is designed for your specific SodaStream setup and the CO₂ cylinder connection being used.

Food-Grade CO₂ for Home Carbonation

The CO₂ used for making sparkling water should be food-grade CO₂. Rapid CO₂ supplies food-grade CO₂ for home carbonation, SodaStream setups, kegerators, restaurants and other beverage applications.

Larger-cylinder setups are alternative configurations and are not approved by SodaStream. If you are considering one of these options, it's important to understand how the setup works and use compatible equipment.

The Bottom Line

A larger 5 lb CO₂ cylinder can give frequent SodaStream users another way to manage their CO₂ supply.

You can either use the 5 lb cylinder to refill your smaller SodaStream cylinder or connect the 5 lb cylinder directly to your SodaStream.

Both options have their advantages. The right choice depends on whether you prefer a cleaner, more familiar setup or the convenience of having a larger CO₂ supply connected directly to your machine.
