The frequency of replacing breast pump parts depends largely on how often you use the pump. Here is a detailed guide based on usage and part type:
Valve Membranes and Valves (Duck Valves)
- If pumping 3 or more times per day , replace valve membranes every 2 to 4 weeks.
- If pumping less than 3 times per day , replace every 2 months (about 8 weeks).
- Valve membranes lose elasticity over time, causing suction loss, so replace at the first sign of fraying, stretching, or reduced suction
Duckbill Valves
- For frequent use (3+ times daily), replace every 3 to 4 weeks.
- For less frequent use, replace every 2 to 3 months.
- These maintain suction and prevent milk backflow
Backflow Protectors (Diaphragms)
- Replace every 6 to 8 weeks if used frequently.
- For less frequent use, replace every 3 to 6 months.
- They ensure leak-free connections and prevent contamination
Tubing
- Replace every 6 months or as needed if there are cracks, moisture, or damage.
- Tubing should remain dry to prevent mold and motor damage
Breast Shields (Flanges)
- Replace every 6 months or sooner if cracked, warped, or uncomfortable.
- Inspect regularly for wear and tear to maintain comfort and fit
Summary Table
Part| Frequent Use (3+ times/day)| Less Frequent Use (<3 times/day)| Reason
---|---|---|---
Valve Membrane| Every 2-4 weeks| Every 2 months| Maintain suction and
elasticity
Duckbill Valve| Every 3-4 weeks| Every 2-3 months| Maintain suction, prevent
backflow
Backflow Protector| Every 6-8 weeks| Every 3-6 months| Leak prevention,
hygiene
Tubing| Every 6 months or as needed| Every 6 months or as needed| Prevent
mold, maintain suction
Breast Shield| Every 6 months or as needed| Every 6 months or as needed|
Comfort, prevent cracks/tears
Regular inspection for wear, tears, discoloration, or loss of suction is essential regardless of schedule. Replacing parts promptly ensures optimal pump performance and milk output
