How often should you replace breast pump valves?

Breast pump valves should be replaced on a regular basis. If you’ve noticed a loss in suction on your breast pump, or a decrease in milk output, the first thing you should check are the valves. How often should you replace breast pump valves? It depends on how often you pump; keep reading to learn more.

Why it’s so important to replace breast pump valves

Your breast pump valves (and backflow protector membranes) are made of a flexible silicone material which stretches and releases each time your breast pump sucks in. This creates the suction you feel on your breast which draws breastmilk out. After a while of regular use, the elasticity of these parts wear down. Think of it like a rubber band: after a while, they lose their ability to stretch and snap back into place. The same thing is happening with your breast pump valve; the pump motor pulls at the valve and releases it on each cycle. When the valve wears down, it makes your breast pump less efficient because the motor has to work harder to achieve the same amount of suction with a slack, used valve than it does with a brand new, tight valve.

How do I know when to replace breast pump valves?

Pay attention to things like a decrease in suction, or a decrease in pumped milk output. If you’ve noticed you’re getting less milk than before or if you’re feeling like your pump isn’t as strong as it used to be, a good first thing to check are the valves (especially if it’s been a couple months since they’ve been replaced). If there’s a tear in your valve, it’s time to replace it.

How often should you replace breast pump valves?

How often you should replace breast pump valves depends on how frequently you pump and what settings you use. It’s a bit of a range. We’ll give a range for daily expressing (1 time per day) and frequent expressing (more than once a day). You should pay close attention to how your pump is performing within these ranges. How often should you replace breast pump valves? Duck valves usually last a bit longer than membranes and come with all new pumps and shield sets as they are generally much more popular and effective with suction.

Duck valves (1-3 months)

Once daily expressing or less: You should expect to replace these once-piece valves every 2-3 months. Frequent expressing: You’ll need to replace these about every 3-4 weeks.   How often should you replace breast pump valves? Membranes as often as every 2 weeks.

Valve membranes (2-8 weeks)

The valve membranes tend to not last quite as long as the duck valves. There is less material in these (which means less waste!) so they wear out more quickly. You’ll want to have plenty of extras on-hand. 🙂 Once daily expressing or less: You should expect to replace the membrane flap about once every 6 weeks. Frequent expressing: You’ll need to replace these about every 2-4 weeks.

Prolonging the life of your Spectra breast pump valve

There are some things you can avoid to make it so your Spectra breast pump valve lasts longer, and will need to be replaced less often: avoid washing the valves in the dishwasher, and avoid frequent sterilisation of the breast pump valves. Avoid steam-sterilising in the microwave. The intense heat of these methods can cause the elasticity to wear down much more quickly. Washing them with warm, soapy water should be enough to clean them. Unless your doctor has stated otherwise, you don’t need to sterilise on a daily basis; just before first-time use. Make sure you remove valves from breastshields everytime when washing, and valve membranes from valve heads before washing. When removing duck valves, don’t pull from the bottom because it’s easier to damage them that way; grab it at the base and gently rock back and forth to loosen the valve from the breastshield.

    Hello, I bought my pump in 2016 and it has duckbill valves. I am having another child shortly and will be replacing the valves – I only need to get the duckbill replacements, is that correct? As in, the pump kit needs either the duckbill valves OR the valve head and membranes?

    • Spectra Team Australia says:

      Hi Katy, you are correct. You only need one valve type, or the other.

      All our new pumps and shield kits come with duck valves now, so if buying a new shield kit, you will receive the duck valves. 🙂

      Good luck with your new arrival! 🙂

    Is it true if the duckbill valves open slightly when not in use, it means they need replacing? I can never remember when I last changed them…

    • Spectra team says:

      Hi Barbara, not really.

      You should replace your valves regularly, depending on how much you use them, or if you notice a suction loss.

      If pumping more than once a day, I would replace every 4 weeks, but if only once a day or less, I would replace every 2 to 3 months.

      If you are sterilising, you may need to replace much more frequently again. 🙂

      Some valves come with the slits slightly apart and they work fine, so this means nothing at all. 🙂
