It takes a bit of time for your body to adapt to a new pump, so don't be discouraged if the results aren't good at the very beginning. eufy Breast Pump has little or no output, this may be because your body needs some time to adjust to the new pump, so don't be discouraged if the results are not ideal or consistent at first. Additionally, here are some troubleshooting steps you can try:

• Inspect the duckbill valve and diaphragm for damage, including cracks, chips, holes, or tears. If a component is damaged, please discontinue using the component and purchase a replacement component.
• Please ensure your eufy Breast Pump has been assembled correctly and the four components (duckbill valve, flange tunnel, diaphragm, and pump hub) are perfectly sealed.
• Please adjust the wearing position and ensure the nipple is at the center of the flange tunnel. Use a full-coverage nursing bra with a flap to create a tight seal between your breasts and the flange.
• Please try a different flange/insert size.
• Please try different suction and rhythm settings.
