Backflow Protector & Membrane (New Version)
Backflow Protector Cover is encase by the Backflow Protector Membrane so there is no possibility of milk crossing the membrane to cause backflow. Backflow Protector Cover caps on the membrane to ensure a secure fit. This new version Backflow Protector also comes with a new version Backflow Protector Membrane.
Backflow protector diaphragms need to be replaced every 3 to 6 months
Just like the valve membranes, the diaphragms in the backflow protectors can stretch and degrade over time, impacting suction. Replace these every 6 months if you pump once or twice a day, and replace every 3 months if you exclusively pump. Inspect this part regularly before you pump because a torn or damaged backflow protector diaphragm can allow moisture into the pump motor, causing irreparable damage and the potential for mould and bacteria to fester. This part does not come in contact with your baby’s milk, so does not need to be washed, unless you see condensation in the part. Then, wash it in hot soapy water and let it air dry and ensure it is completely dry before use again. The backflow protector is the heart of a closed system pump and protect your baby’s milk from contaminants and bacteria that could cause harm, so take great care of these. If not changed regularly, they will impact suction strength.
