halley_welz 1. It was very difficult to find materials the right size for the washer. For more cost, the correct washer should be included.
2. You should trim them ahead of time, because although we followed your directions we could not get the clamp to secure to the bottle top. This caused water to spray everywhere.
halley_welz I followed the directions for trimming and adding a rubber washer in place. The adapter fits nicely onto the glass carafe, but does not allow the soda stream machine to close properly. Any suggestions?
