FAQs: 

Q: How to avoid breaking the backflow protector during setup with the flange?
A: Turn to insert the backflow protector into and off from the flange with care. DO NOT push in or rock straight in and out with force. It will break.

Q: Does the bottle include a nipple?
A: No, the bottle includes one-piece cap WITHOUT nipple.

Q: Where can I find the size marking on the flange?
A: It is marked at the end of the nipple tunnel.

Q: How do I choose the flange sizes?
A: Since your nipples will enlarge after pumping, measure the diameter of your nipples AFTER a pumping session. Do NOT include the areola. Refer to size selection guide in the product photos at the top of this page.

Q: How do I clean them?
A: Disassemble all parts. Clean them with soapy water, and rinse with tap water. Sterilize all parts with water steam for 15 minutes or in boiling water for 5 minutes. When using boiling water, make sure to cover all parts with water to avoid melting them.

Q: Are they dishwasher safe?
A: You may dishwasher flanges, bottles and backflow protectors on top rack with LOW heat drying. However, we DO NOT suggest dishwashing the duckbill valves. Please handwash the valves with care.
