Troubleshooting your Spectra Breast Pump: Backflow Protector & Duckbill Valve

When it is time to replace a Spectra Backflow Ptotector or Valves?

1. Reduced Suction

If you’re noticing a reduction in suction while pumping, this is a sign it is time to replace your Spectra Backflow protector and Spectra duckbill valves.  Valves may need replacing more often than the backflow protector, but not less often so a good rule of thumb is if your backflow protector needs to be replaced, replace your valves at the same time.  Thes two Spectra parts are the most critical when it comes to suction and worn out valves and backflow membranes are the most common reason for reduced suction.  Please note that if you are testing suction, you will need to use your Spectra Air Cap port cover in order to close off the other tubing.

What about no suction when I’m pumping?

A sudden loss of suction while pumping is most often because the backflow protector is not assembled correctly or duckbill valve or is not attached correctly to the breastshield, or has fallen off.

What if the backflow protectors still moving when your pump is on?

If the backflow protectors are still moving back and forth with the sucking motion of the pump or if the backflow protectors fall off, then chances are the suction issue is because of the membranes. When they lose suction or fall off, it’s usually because they have worn down and it’s time to replace them. Check to make sure your membranes are still properly assembled to your kit, and remember that to properly maintain the pump. 

How often does Spectra recommend replacing Backflow Protectors?

Backflow protectors should be replaced regularly, as often as every two to three months.  Any time your breast pump has been stored, duckbill valves and backflow protectors should be replaced as well as any brittle or crimped tubing.

2. Backflow Protectors are Flopping Around

If your backflow protectors are moving erratically or hitting the casing, this usually means the duckbill valves need to be replaced.

3. Moisture in the Backflow Protector

While condensation is common on the breast shield side of your backflow protector, moisture on the side where the tubing is attached is a problem that can then create moisture in the tubing. If your parts are completely dry prior to assembly, but you notice moisture in the tubing during and after pumping, it’s most likely an issue with the backflow protector. Improper assembly of the backflow protector or a broken or worn out backflow protector will allow condensation to built up while pumping. Once moisture enters the tubing, there’s no way to safely clean, dry, and sterilize it. You also risk getting moisture into the pump motor itself, which can cause damage to your pump motor and grow mold. This is why backflow protectors need to be replaced regularly.  Working mothers or moms who pump exclusively shoud always have extra Spectra valves and Spectra backflow protectors on-hand for for when you need them.  Your milk supply will thank you!

4. Valves Don't Snap Back into Place

Spectra breast pump valves and backflow protector membranes for that matter are made of a flexible silicone material which stretches and releases each time your breast pump cycles. This creates the suction you feel and that draws out your breastmilk. After regular use, the elasticity of these parts break down. When the valve wears down, it makes your breast pump less efficient because the motor has to work harder to create the same amount of suction.

5. Valves Fall Off

If your valves fall off, the most common cause is that the elasticity has been compromised and it is time to change your valves.  If you purchased new valves, but they fall off your breast shield anyway, this may be because of the changes heat has made to the breast shield during sterilization.  If this happens, you will need to replace the breast shield as well.

6. Torn Valves

If you notice a decrease in suction or if you’ve noticed your pump doesn't feel as strong as before and you’re getting less milk, take a good look at your valves.  If it has been more than a month since you have replaced them or if there is a tear in your valve, it’s time to replace it.  Tears most often occur at the tip of the valve.  

How often does Spectra recommend replacing breast pump valves?

How often Spectra recommends replacing valves depends on how frequently you pump.   If you pump once daily, you may only need to replace valves every two to three months.  If you pump frequently such as for working or exclusive pumping, every four weeks is recommended.  

Keeping a Spectra Spare Parts Kit on hand is always a good idea!
