How do you prepare a cylinder refill adapter to connect to your SodaStream?

SodaStream Cylinder To ensure the SodaStream cylinder will accept its full capacity of gas / liquid CO2, it is recommended to put the SodaStream cylinder in a freezer for 2 hours prior to refilling. This is not essential, but it will ensure the cylinder is filled to full capacity. Freezing lowers the pressure inside the cylinder, which enables it to readily accept more CO2.

How do you connect the SodaStream refill adapter?

  1. Connect the refill adapter to the parent/donor cylinder at the adapter inlet. Tighten using a spanner or wrench (do not hand-tighten).
  2. Ensure the shutoff valve on the adapter is closed by turning fully clockwise. Use gentle/moderate force to tighten, as over-tightening may damage the valve.
  3. Turn the knob of the SodaStream isolation valve fully anticlockwise. This will retract the pin inside the adapter which ensures when the SodaStream cylinder is screwed in, it will not press the SodaStream valve to release the gas.
  4. Screw the SodaStream adapter into the refill adapter body. The output of the SodaStream adapter may point in any direction, rather than vertically as shown, this is not a problem and will not affect the refilling of the cylinder.
  5. Screw the SodaStream cylinder into the adapter. Tighten until the cylinder slips in your hand.
  6. Open the valve on the parent/donor cylinder to release the gas.
  7. Turn the knob of the SodaStream isolation valve in a clockwise direction until it cannot be turned any further.
  8. Slowly turn the shutoff valve anticlockwise, which will release the gas from the refill adapter. You will hear gas begin to enter the cylinder.
  9. Continue to refill until either the pressure indicated on the gauge reaches the pressure of the recipient cylinder or you can no longer hear gas being transferred. Once refilling is complete, turn the shutoff valve clockwise to shut off the CO2.
  10. Turn the knob of the SodaStream isolation valve anticlockwise to isolate the SodaStream cylinder.
  11. Slowly turn the purge/dump valve anticlockwise to release the residual gas contained in the apparatus. Upon doing so, you will hear a pronounced ‘hiss’ – this is normal. Once all of the gas has been released, turn the valve clockwise to close it again for next use.
  12. Remove the SodaStream cylinder from the adapter.
  13. The weight of the refilled cylinder should then approximately equal the weight specified on the cylinder.
  14. Once you have finished refilling all cylinders, close the valve on the parent/donor cylinder by turning clockwise and then dump the residual trapped gas in the apparatus by turning the shutoff valve anticlockwise.

CO2 Adapter For Your Sodastream Refill Additional Tips

  • To prevent underfill – close the Donor tank valve, then open the release valve on the side of the adapter, prior to unscrewing the bottle.
  • The lower the Sodastream cylinder temperature, the lower Sodastream cylinder internal pressure, the easier it for CO2 to flow from the Donor tank. Sodastream cylinder after freezer will increase max filled capacity.
  • It might take several fills (up to 4) to reach Max capacity.
  • Keep the normal Donor tank in an inverted position and NOT invert the Soda Siphon Donor tank. The Siphon Donor tank has an internal tube that reaches the bottom so what comes out is liquid CO2. Gaseous CO2 is always at the top and inverting the Siphon Donor tank will make the internal tube reach the gaseous CO2 and will reduce filling capacity. The upright position for a normal (none Siphon) Donor tank is wrong for the same reason.
  • Gunk, corrosion has built up around the Sodastream cylinder internal valve. If you have more than one cylinder available, the easiest way to test for issues with the valve is to swap cylinders.
  • New design Sodastream cylinders with the flat valve are more difficult to refill. If a Sodastream cylinder valve has a pin, it will be much easier to refill.
