  • Q How often should I replace breast pump accessories?

    A
    To maintain optimal performance and hygiene, regular replacement of pump accessories is essential, especially if you notice suction issues or visible wear and tear.
    Recommended Replacement Timeline:
    Silicone parts (like Duckbill Valves, diaphragms): Every 1–3 months
    Other parts (such as flanges, Tubings, milk collectors): Replace based on usage or if damaged
    Immediately replace any parts that show signs of:
    Cracking
    Fraying
    Stretching
    Reduced suction or improper fit
    Regular inspection and timely replacement ensure better pumping efficiency and protect your milk supply and breast health.

  • Q How to measure my breast pump flange size?

    A
    To find your correct flange size, measure the diameter of your nipple (do not include the areola), preferably in millimeters. Then refer to the flange sizing chart provided by NCVI. Choosing the correct flange size is crucial for comfort and effective milk expression. A poor fit may cause pain, reduce milk output, or damage nipple tissue.

  • Q Pain?

    A
    Pain during pumping is not normal and often indicates a problem with flange fit, suction level, or positioning.
    Steps to reduce discomfort:
    1. Check flange size: A flange that is too large or too small can cause nipple pain or damage.
    2. Adjust suction level: Start with a lower setting and increase gradually if needed.
    3. Always ensure your pump is correctly positioned and fits comfortably for a pain-free experience.

  • Q Leak?

    A
    Leaks can occur for several reasons. To prevent leaking, ensure proper posture, correct assembly, and timely part replacement.
    Common Leak Points and Solutions:
    Motor or collection cup: May not be securely connected, or the cup could be cracked. Make sure everything is sealed tightly.
    Pour hole: Check that the notches on the silicone shield and collection cup are properly aligned during assembly.
    Flange hole: May leak due to reclining too far. Also check if the duckbill valve is worn or torn.
    Replace parts every 1–3 months to maintain proper sealing.

  • Q Transfer?

    A
    If you are transferring milk: Use a clean and sterilized container to pour slowly to avoid spilling.
    If you are traveling with a breast pump:
    1. Make sure the power voltage matches your destination.
    2. Consult the airline's regulations before boarding the flight.

  • Q No suction?

    A
    If your breast pump is not producing suction, follow these steps:
    1. Check Duckbill Valves and membranes: Remove and inspect for damage like cracks, chips, or tears. Parts should fit snugly and lie flat. Replace any worn pieces.
    2. Confirm flange size: An incorrect flange size can lead to poor suction or no milk expression.
    3. Adjust settings: Try changing suction levels or modes.
    4. Ensure that all parts are assembled correctly and airtight before use.

  • Q Making a noise?

    A
    It is normal for breast pumps to make mild noise during operation, as the motor naturally generates sound while running. However, if you notice unusually loud or strange noises, it may indicate that a part is loose, improperly assembled, or damaged.
    Here are some steps to troubleshoot noise or squeaking:
    1. Keep parts dry before use – Moisture may lead to squeaking or slippage.
    2. Check for damage – Inspect all accessories to ensure they are intact and undamaged.
    3. Confirm correct assembly – Make sure all parts are installed securely and aligned properly.
    Ensure proper fit – The pump should be snug against your breast with no gaps. Wearing a well-fitted nursing bra can help keep the pump in place and reduce vibration or noise.
    If the noise continues despite following these steps, please contact our support team so we can help resolve the issue promptly.
