Frequently Asked Questions

Q: Are these duckbill valves and silicone diaphragms compatible with all wearable breast pumps?

A: These replacement parts are specifically designed for V1 and V2 wearable breast pumps. Please confirm your pump model before purchasing to ensure a proper fit. They are not guaranteed to be compatible with other pump brands or models.

Q: How often should I replace the duckbill valves and diaphragm on my breast pump?

A: Most lactation consultants recommend replacing duckbill valves every 4–8 weeks with regular use, as worn valves can significantly reduce suction strength. Silicone diaphragms should be inspected regularly and replaced if you notice cracks, tears, or a decrease in pump performance.

Q: How do I clean and sterilize these silicone breast pump replacement parts?

A: These silicone accessories can be rinsed with warm, soapy water after each use. They are also safe for steam sterilization or sterilizer bags. Always allow parts to air dry completely before reassembling your pump to prevent bacteria growth.

Q: Which package option should I choose?

A: If you're just restocking valves, Package D (4× Duckbill Valves) is a great choice. For a full replacement kit, Package A or C (valves + diaphragm) is recommended. Package B is ideal if you only need to replace worn diaphragms.
