Duckbill valves are wear-and-tear parts that naturally soften and lose elasticity over time. Replacing them regularly helps:

• Maintain strong, consistent suction
• Improve milk output
• Prevent leaks and milk backflow
• Ensure hygienic pumping sessions

For best performance, it is recommended to replace duckbill valves every 1–2 months, depending on usage.
