Be sure to examine your pump parts regularly, if you notice damage or extensive wear replace immediately.
Medela recommends replacing your membranes every 3 – 6 months, depending on your pumping frequency. IMPORTANT: Use of pump parts or accessories not designed for your specific breast pump may cause irreversible damage to the product. For that reason, only use the accessories that came with, or are identified by Medela to work with, your specific breast pump model.
