FAQs

Does this cylinder fit the ProCook Sparkling Water Maker?
Yes. It uses the standard screw-in CO₂ connection, which this 425g cylinder is made for.

How much sparkling water does one cylinder make in a ProCook Sparkling Water Maker?
Up to 60 litres. At around a litre a day, that's six to eight weeks for most households, depending on how fizzy you like it.

Will a SodaStream Quick Connect cylinder fit my ProCook?
No. Quick Connect cylinders use a click-in valve that only fits SodaStream's TERRA, ART, DUO and similar machines. Your ProCook needs a screw-in cylinder like this one.

What do I do with my empty cylinder?
Gas4U offers an empty-cylinder return service. Eligible one-off customers can return empty cylinders for store credit towards a future order. Refill Club subscribers can arrange returns through the subscription renewal process.

Not sure which cylinder you need?
Use the Gas4U Compatibility Checker before ordering to confirm the correct cylinder connection for your sparkling water maker.
