Your reminder that your pump parts have an expiration date ⏰
Not everything needs replacing constantly… but some things absolutely do.
What needs to be replaced + when:
🔁 Valves & membranes (the small silicone flappy parts)
Every 2–4 weeks if pumping daily
→ These wear out FAST and directly affect suction
🔁 Duckbill valves
Every 4–6 weeks
→ If they don’t close fully or look stretched, your output can drop
🔁 Backflow protectors (diaphragms)
Every 2–3 months
→ Especially important for maintaining a closed system + hygiene
Everything else? Replace as needed, not on a strict schedule:
🧩 Flanges
→ Replace if cracked, warped, or uncomfortable
🧩 Tubing
→ Only replace if there’s condensation, mold, or damage
🧩 Bottles/connectors
→ Replace if cracked, cloudy, or not sealing properly
Quick reality check:
If your output drops, don’t panic and assume your supply changed.
Start here first 👇
✔️ Check your membranes
✔️ Check your valves
Most of the time, it’s not your body… it’s your parts.
Save this so you’re not second-guessing your pump later.
