How Often & When To Replace Breast Pump Parts

Electric breast pumps are really a godsend for nursing and pumping moms. They help feed babies when mom has to be away from them or if nursing just isn’t working out.

Because of this you want to keep your breast pump and its parts in the best shape possible. Breast pumps are excellent for helping with milk production, and even better for preparing bottles in advance so that dad can do some night feeds.

In this article we will go over why it is important to replace breast pump parts, how often to replace breast pump parts, and what you can do with the ones you no longer need.

Why Do You Need to Replace Breast Pump Parts?

When you use a breast pump you could be using it once or twice a week, or multiples times a day. For example if you are pumping at work on a set schedule or if you need to stick to a pumping schedule because you are pumping exclusively you will be pumping a lot.

This will inevitably lead to wear and tear, meaning your breast pump parts will need to be replaced. Over time, regular use can lead to the harder working parts of your breast pump being significantly worn out, stretched or frayed.

When the parts start to deteriorate breastfeeding moms may get the feeling that their milk supply is no longer optimal or even that the breast pump itself is broken or damaged. If you feel your breast pump is not working quite as well as it used to, the first step is to check whether it needs parts replaced.

Bacteria build up is also a real concern because overused parts can form crevices and cracks, making it a little more difficult to keep clean.

How Often Do You Need to Change or Replace Breast Pump Parts?

The answer to this question is that each part has a different lifespan due to its placement within the breast pump and the material it is made of. Let’s take a look at the most replaced parts below and how often each needs to be checked and possibly replaced.

Valve Membranes

These are the little white flaps that attach to the valves of the breast pump. Valve membranes will stretch over time and lose elasticity, which will affect suction power. Therefore, membranes should be replaced every 2 weeks to 2 months depending on usage.

One way to tell if a membrane is worn out is to feel how thick it feels compared to an unused membrane. I always knew it was time to replace the membrane because I could feel how much thinner it was than a new one.

Valves (Sometimes Called Duck Valves)

Breast pump valves or as some companies call them, duckbill valves are the plastic pieces the breast milk goes through before entering breast milk storage container. The valve membranes mentioned above, attach to the top of the valve.

Valves need to be replaced every 1 to 3 months. This time frame will depend on how often the device is used. Worn out duck valves can affect suction power.

Backflow Protector

Some breast pumps have backflow protectors. These can also stretch and degrade over time.

They lose elasticity and can greatly impact suction power and therefore milk flow. Backflow protectors should be replaced every 3 to 6 months, depending on how often you use the breast pump.

Tubing

There are conflicting ideas as to when tubing should be replaced, but the general rule of thumb would be to replace tubing every 3-6 months. The reason is because when the tubing starts stretching and slipping off, it can leave the motor exposed and moisture could get inside and damage it.

Just be aware of how the tubing looks and try not to let any excess moisture enter it or the motor.

Breast Shields or Flanges

Breast shields are also referred to as flanges. They are the part that attach to your breasts.

Residue can easily build up on these parts as they are sometimes difficult to keep completely clean. Ideally you will be replacing breast shields every 6 months, or as soon as you see cracks or tears in the shield.

What Can You Do With Old Breast Pump Parts?

This is a good question and there are a few answers depending on the part.

  • Valves or Duck Valves: can be recycled
  • Backflow protectors: if it is hard plastic it can be recycled, but if it’s soft silicone it must be thrown away
  • Membranes: must be thrown away
  • Breast shields / flanges and connectors: can be recycled

Remember, you can also keep your pump for future babies, but make sure to replace all used parts beforehand.
