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. Compatibility note:. Flange inserts can be used with both s12 pro and s12 pro quick. Other accessories are designed specifically for each model, please choose the version that matches your pump.
