Troubleshooting
If you encounter issues with your Phanpy Milk Collector Cups, consider the following:
- Reduced Suction:
- Ensure all parts are correctly assembled and securely sealed. A loose connection can cause suction loss.
- Check the duckbill valve for tears or damage. Replace if necessary.
- Verify that the tubing is properly connected to both the cup and the pump unit, and that there are no kinks or blockages.
- Leaking Milk:
- Confirm that the breast shield is properly sealed against the Newcup and that the top cover is securely in place.
- Inspect the silicone flange and duckbill valve for any damage or wear that could compromise the seal.
- Ensure the cup is not overfilled beyond its maximum capacity (6 oz / 180 ml).
- When pouring, ensure the top cover is fully sealed to prevent spills.
- Discomfort During Pumping:
- Ensure your nipple is centered in the flange.
- If the 24mm flange feels too large, try using the included 20mm insert. Correct flange sizing is crucial for comfort and efficiency.
- Adjust your breast pump's suction settings to a comfortable level.
