Some breast pump accessories do need replacing regularly to maintain performance. If you notice that your pump seems to have lost suction, the first thing you should do is take a look at your parts, particularly the valves, and inspect for wear, fraying, or stretching and replace if needed.

1. Diaphragm and duck valves need to be replaced every 3 months;

2. Backflow linker and flange shields need to be replaced every 6 months

    Flange size

    I honestly do not understand how all these big brand companies decide that 24 mm or 21 is the standards size. I am so glad that these exist if not I would stop pumping. Happy that it came with many different sizes for an affordable price and for them to be so sturdy. Great product!
