Assembling and Using a Cylinder
To assemble and use a SodaStream cylinder, start by placing the gasket in the connector of the filling adapter and screwing it onto the valve of the large CO₂ tank. Tighten the connection until it's snug. Ensure both adapter valves are in the closed (90°) position.
Before filling the cylinder, put it in the freezer for at least an hour to make the filling process more efficient. This will help the liquid CO₂ expand less with heat. If your CO₂ tank doesn't have a dip tube, you'll need to hold the tank upside down during the filling process or lay it on its side for larger capacity tanks.
To use the cylinder, screw it onto the pin knob connector, ensuring the pin is unscrewed. Then, screw in the pin knob to open up the SodaStream cylinder valve.

Cylinder Problems
If you're experiencing issues with your SodaStream cylinder, there are a few things to keep in mind. To refill the cylinder completely, it's essential to have it as cold as possible, ideally by putting it in the freezer for at least an hour before starting the filling process.
For a smooth filling process, it's a good idea to weigh the small cylinder on a food scale, as it can take approximately 1-2 minutes to reach its full capacity. This will help you track the progress and ensure you don't overfill the cylinder.

Be aware that as the large CO₂ tank empties, the pressure inside will drop, making filling the smaller bottle increasingly difficult. This is usually when you have around 2 lb of CO₂ left in the bottle, and you may need to partially fill the smaller cylinder, requiring repeated refreezing to reduce the internal pressure.
If you have a large CO₂ tank without a dip tube, it's best to lay it on its side, such as on a mattress, to allow the liquid CO₂ to flow into the recipient cylinder. This is because liquid CO₂ tends to keep at the bottom of the bottle, so we need to keep it at an angle during the filling process.
If your SodaStream canister is damaged, don't attempt to refill or use it. Contact SodaStream or a qualified professional for inspection and replacement, as using a damaged canister can be extremely dangerous.

Residual Pressure Valve Awareness

Some CO₂ tanks have a Residual Pressure Valve (RPV) that prevents contamination.
This valve often has a unique shape, like a square, round, or triangular middle part.
If you have an RPV valve, you'll need to remove it or get a special adapter to refill your CO₂ tank.
Most refilling adaptors aren't compatible with RPV valves, so it's best to look for a CO₂ cylinder without one.
