The suction of my Philips Avent Manual Breast Pump is low

Published on 04 September 2023
If your Philips Avent Manual Breast Pump does not seem to have enough suction, see the tips below on how you can resolve this issue.
Make sure that the breast pump has been cleaned. Also, assembling the breast pump while it is still a bit moist from disinfecting can help to improve the vacuum.
If not correctly assembled or if any parts are damaged, the breast pump can leak air, reducing the suction power.
  1. Insert the white valve into the pump body so that it fits securely into the small round hole. Make sure the pointed side of the valve is facing down and it is not damaged.
  2. Fit the silicone diaphragm with stem into the pump body. Ensure a perfect seal around the rim by pressing down with your fingers (you may find it easier to assemble if the diaphragm is wet).
  3. Make sure the cushion is securely attached to the pump body. Make sure the inner part of the cushion is pressed all the way up to the line (indicated with an arrow). Secure the rim around the funnel making sure there are no gaps (you may find it easier to assemble if the cushion is wet).

The breast pump may also show low suction before expressing. Make sure that the pump is positioned correctly on the breast to allow a seal between the breast pump and the breast.
Do not mix parts of other breast pumps that do not belong to the Philips Avent breast pump range.
