Valve and Membrane Check
• Remove and separate valve from membrane.
• Inspect the valve for chips or cracks. Inspect the membrane for holes or
tears. If flawed or damaged, replace valve and/or membrane prior to
pumping.
• Wash valve and membrane per Cleaning Section 4.
• Reassemble. Make sure the membrane lays flat on the valve and if it does
not, replace the valve and/or membrane prior to pumping.
Breast Shield and Pump Body Check
• Inspect breast shield and pump body to make sure there are no cracks and
they securely attach to each other.
• Make sure the stem assembly on the pump handle is seated all the way into
the pump body until it will go no farther.
• Make sure the white O-Ring on the stem handle is in place and not
damaged.
• Make sure the pump body is firmly screwed onto the bottle and that the
breast shield is firmly seated into the pump body.
• Make sure the oval base of the stem is properly seated in the oval base of
the diaphragm.
• Make sure the diaphragm is pushed all the way onto the circular rim on the
underside of the handle.
• Make sure the breast shield forms a complete seal around the breast.
• Ensure your breast pump is assembled correctly and that there is suction.
• Relax and take a 10-15 minute break if let down is not achieved after 2
consecutive pumping sessions.
• Consult with your healthcare provider or breastfeeding specialist if
expression does not occur.
