Why You Need to Replace Parts on Your Night Owl Wearable Breast Pump
Our Night Owl Wearable Breast Pump is a game-changer when it comes to hands-free pumping. Designed for convenience and efficiency, it allows you to express milk discreetly and comfortably. However, to ensure optimal performance, it’s essential to regularly replace key pump parts.
Many mums don’t realise that even high-quality pump components wear out over time. When parts degrade, suction weakens, milk output drops, and pumping can become uncomfortable. In this guide, we’ll cover:
- Why breast pump parts need replacing
- The recommended replacement schedule for Night Owl pumps
- How worn-out parts impact suction and milk supply
- Signs that it’s time to replace parts
The Science Behind Breast Pump Wear and Tear-
Our Wearable Breast Pump works by creating a vacuum seal and rhythmic suction to express milk. The pump relies on silicone membranes, valves, and shields to maintain a proper seal and gentle but effective suction.
Over time, these components naturally stretch, lose elasticity, or develop microscopic wear, leading to:
❌ Weaker suction → Reduced milk removal
❌ Longer pumping sessions → Less efficient milk expression
❌ Milk leakage → Loss of vacuum seal
❌ Discomfort or irritation → Pump parts may not fit correctly as they degrade
By replacing worn-out parts on time, you can maintain strong suction, maximise milk output, and ensure a comfortable pumping experience.
When to Replace Night Owl Breast Pump Parts-
To keep your Night Owl pump functioning at its best, follow this recommended replacement schedule:
Valves (Every 1–2 Months)
Why? These control suction strength by opening and closing during pumping. Over time, they lose their flexibility, leading to weaker suction and decreased milk output.
When to replace?
- If pumping 3+ times daily → Replace every 4 weeks
- If pumping 1–2 times daily → Replace every 1-2 months
- If suction feels weaker or milk output decreases, replace sooner.
💡 Tip: If your milk flow has slowed or suction feels less powerful, swap out the valves first!
Diaphragms (Every 1-2 Months)
Why? The diaphragm creates the vacuum seal needed for effective suction. Over time, stretching and microscopic tears reduce suction power, leading to longer pumping sessions and lower milk output.
When to replace?
- If pumping 3+ times daily → Replace every 1 months
- If pumping 1–2 times daily → Replace every 2 months
- If you notice air leakage or reduced suction, replace immediately.
Breast Shields (Every 2-3 Months)
Why? The soft silicone shields (flanges) flex and conform to your breast during pumping. Over time, wear and tear can affect fit, leading to less effective suction, discomfort, or even nipple pain.
When to replace?
- Every 2-3 months or sooner if shields feel loose, show cracks, or become uncomfortable.
- If you experience nipple pain or a change in suction, check for warping or rough edges.
💡 Tip: Make sure you’re using the correct flange size for maximum comfort and milk output!
Collection Cups (Every 6–12 Months)
Why? The collection cups and silicone seals are essential for maintaining a leak-proof seal. Over time, seals may loosen or degrade, leading to milk leakage or loss of suction.
When to replace?
- If you notice milk leaking from the cup or air escaping during pumping.
- If your pump isn’t maintaining suction as well as before.
- At least once a year, even if they look fine.
💡 Tip: Always check the alignment of the seals and collection cups before each pump session!
Pump Motor & Battery Care (Every 1–2 Years)
Why? While the motor itself is durable, frequent use over time can lead to weaker suction power. If you’ve replaced all other parts and still experience reduced efficiency, it may be time for a motor replacement.
Battery Care for Longevity-
Your Night Owl Wearable Breast Pump is powered by a lithium-ion battery, which requires proper care to maintain its lifespan. Just like your phone battery, lithium batteries degrade over time, impacting the overall performance and suction strength of your pump.
Here’s how to extend battery life and ensure your pump maintains optimal performance:
Avoid overcharging – Unplug your pump once it reaches 100% to prevent battery strain.
Charge before full depletion – Try to recharge before the battery drops below 20% to extend longevity.
Use the correct charger – Always use the original charging cable or a compatible one with the right voltage to prevent battery damage.
Store properly – Keep your pump in a cool, dry place when not in use to prevent heat-related battery wear.
If the pump isn’t holding a charge well or takes longer to reach full power, it may be time for a battery or motor replacement.
When to replace?
- If your pump is over a year old and suction has weakened despite replacing parts.
- If the motor sounds weaker, louder, or inconsistent.
- If the battery no longer holds a charge well or takes significantly longer to charge.
Signs It’s Time to Replace Parts-
Even if you’re following a replacement schedule, some signs indicate that parts need to be swapped out sooner:
- Suction feels weaker than usual
- Longer pumping sessions with lower milk output
- Milk leaking from unexpected places
- Clicking or hissing sounds from the pump
- Condensation or moisture inside the pump parts
- Discomfort or nipple pain during pumping
If you notice any of these issues, try replacing your valves or diaphragms first, as they are the most common culprits!
How to Maintain Your Night Owl Wearable Breast Pump-
To extend the life of your pump and keep it working efficiently:
Clean and dry all parts after every use to prevent bacteria buildup.
Store pump parts properly – avoid exposure to excessive heat or direct sunlight.
Inspect parts regularly for signs of wear, cracks, or stretching.
Have spare parts on hand so you’re never caught without replacements.
By keeping up with regular part replacement and maintenance, you can ensure that your Night Owl Wearable Pump continues to support your breastfeeding journey comfortably and efficiently.
