Is Your Breast Pump Losing Suction?

If you are experiencing low suction, first check the valves and membranes:

  1. Separate the membranes from the valves.
  2. Inspect the valves and membranes for damage, including cracks, chips, holes, or tears, and make sure the pieces fit snugly and lie flat. If a part is damaged, discontinue use and purchase a replacement.
  3. Wash the valve and membrane using warm, soapy water. Allow parts to dry completely before reassembling.
  4. Reassemble your breast pump, ensuring that each piece fits snugly and lies flat.
  5. Check the breast shields and connectors to make sure there are no cracks, and make sure they attach securely.

Is There Moisture in Your Tubing?

If you notice condensation in your tubing:

Leave your tubing attached with the pump still running while you store your breast milk after you’re finished pumping.

This will allow any condensation that has formed from the natural results of humidity to dry in the tubing.

Is There Milk in Your Tubing?

If milk accidentally gets in the tubing:

  1. Turn off the pump and remove it from the power source.
  2. Remove tubing without wiggling or pulling at an angle.
  3. Wash tubing in warm soapy water and hang to dry thoroughly.
  4. Snap off the faceplate using the thumb tab and soak in warm, soapy water for 5 minutes.
  5. Clean with a soft brush or dish cloth and allow it to dry fully.
  6. Wipe diaphragm clean with a damp cloth (no soap).
