Why doesn’t my Crystal make a buzz sound when carbonating?

Glad you noticed! SodaStream is always looking for ways to improve the consumer experience. We took your feedback and in 2020 upgraded the Crystal Sparkling Water Maker with a new, silent valve. Now you can create those bubbles without alerting the dog!

You may have a Sparkling Water Maker that makes noise while carbonating – don’t worry, this is a standard part of the carbonation process.
