2. Full the sipper part up until it is fully open as shown below. The air release valve is part of the sipper.
3. Now push the sipper down a little and start drinking. You may be able to adjust with well drinking to get the right flow for you.
4. If your sipper part has worn and needs to be replaced, please contact us for a 4 pack replacement part.
