What to do if my Medela Swing has low suction?
- CCaitlin CarsonAug 21, 2025
If you experience low or no suction with your Medela Breast Pump, verify that the valve head and membrane are clean and undamaged. Ensure the membrane is correctly attached to the valve head and check the valve's lateral position. Inspect all connections, making sure the tubing ends are securely fitted into both the connector's back and the breast pump's port. Avoid kinking the tubing during expression, and confirm that the breast shield creates a complete seal around the breast.
