If you're a mama who uses a breast pump, even just here and there, it's helpful to know that you'll want to replace the individual parts to keep it performing at it's best. Over time the pump can start to lose suction and inadequately pump your breastmilk, which we know isn't a good thing! So read on for maintenance tips.
Valve Membranes: 2-8 weeks
If you're exclusively pumping you'll likely need to replace these membranes every 2-4 weeks. If you only pump once or twice a day then you may be able to make it up to 8 weeks before needing to replace them. If you notice that these flaps are no longer laying flat or you feel like your pump is losing suction, replacing these membranes is a good place to start.
Duckbill Valves: 4-12 weeks
Loss of suction can also occur when these need replaced. These silicone valves can become loose and stretched out over time from repeated use and washing.
Backflow Protector Membrane: 3 to 6 months
If you're exclusively pumping you'll likely want to replace these around every 3 months and if you're pumping once a day you may be able to wait until closer to 6 months. Like the valve membranes and duckbill valves, these too can become loose over time and with repeated washing.
Breast pump Tubing: 3 to 6 months/ as needed.
If you notice your tubing has become dirty or moisture is now building up in the tubing it is a good time to replace it. The back flow protectors are meant to prevent moisture from getting into the tubing but it can still happen. Unfortunately you're not able to sterilize the tubing yourself so it's good to have a backup set on hand.
Breast shield / Flange: Every 6 months or as needed.
While this piece often lasts a while it's important to keep an eye out for any cracks or build up of residue that washing or sterilizing is no longer removing.
