Backflow Protectors

How do I use backflow protectors and what pumps are they compatible with?

These spaceship looking parts are designed to stop backflow of milk from entering into the tubing and causing mold and bacteria growth.

Backflow can also ruin a pump if the breast milk gets inside. These Maymom Backflow Protectors are compatible to be used with all Spectra pumps.

Valves and Membranes

How often should I replace the valves and membranes and what happens when I do?

These parts are specifically for Medela breast pumps.

Valves and membranes should be replaced about once every 6-8 weeks or more frequently depending the type of use your breast pump is getting.

I could easily change mine once a month. Keeping these breast pump parts new will hugely help with milk output as they are responsible for the suction capability of the pump.

Replacing the tubing isn’t something you need to do as frequently.

A tip to keep the tubing and pump’s seal tight, cut the stretched end that goes onto the pump.

After doing this so many times, the tubing loses length and that’s when it’s nice to replace it with a fresh set.

Breastshields and Connectors

Why should I replace these parts?

I’ve had to size down my breastshields multiple times throughout the last nine months of exclusively pumping. Also, accidents happen.

If you’re sanitizing your parts on the stove in a boiling pot of water and just so happen to forget about them for a few hours, you may just find yourself a melted blob of boobie parts.

Thankfully, I have not does this, but I did just read a cute post in the exclusively pumping facebook group I’m in where a mom confessed to this happening to her.

Why would I need these attachments?

These custom breastshield replacements for Medela flanges are designed to be more comfortable to wear.

They keep elastic breast tissue from being pulled too deep into the flange. The sizes range from xs-m. They are angled downward to keep you in a more comfortable position while pumping that encourages more milk to flow.
