Solution

1. Clean and Dry the Parts: Remove the duck bill valve. Clean and completely dry the valve and its connection area.
2. Reinstall the Duck Bill Valve: Align the base of the duck bill valve with the connection point. Press the base straight down until it is fully attached. Do not pull or press the tip of the valve during installation.
3. Test with Another Valve: Replace it with another clean, dry duck bill valve and check whether it stays attached. If the replacement valve stays in place, stop using the original valve.
