Why Replace Your Duckbill Valve Regularly?

Over time, silicone valves can stretch, tear, or lose their seal — reducing suction efficiency and allowing bacteria to build up. Replacing your duckbill valve every 1–2 months ensures your pump maintains maximum suction and your milk stays uncontaminated.
