How often to replace breast pump parts? [Medela, Spectra, Elvie]

If you are a breastfeeding mom, you may be using a breast pump to collect milk. It’s important to keep your pump in good condition by regularly replacing its parts. In this blog post, we will tell you how often to replace the different parts of your breast pump, such as duckbill, tubing, membranes, flanges, backflow protectors and etc. We will also provide tips on how to care for your pump. Keep reading for more information!

So, how often do replace breast pump parts?

Breast pumps are an essential tool for mothers who are unable to breastfeed their infants directly. While most pumps come with a variety of accessories, the two most important parts are the pump itself and the nipple shield.

The pump should be replaced every 6-12 months, depending on how often it is used. The nipple shield, on the other hand, should be replaced every 3-6 months. This replacement schedule will help to ensure that the pump is working effectively and that the nipple shield is not worn out.

In addition, it is important to regularly clean all of the parts of the breast pump, as well as the storage containers and tubing. By following these simple guidelines, mothers can rest assured that their breast pump will provide their infant with the best possible nutrition.

Duckbills (Duck Valves)

Duckbills are an important part of breast pumps, and they need to be replaced regularly to ensure that the pump is working properly. Duck valves are made of rubber, and over time, they can become worn out or cracked. When this happens, they can no longer create a seal, which means that air can leak into the pump and reduce its suction.As a result, it’s important to check your duck valves often and replace them when necessary.

Most manufacturers recommend replacing duck valves every three to six months.

However, if you notice that your duck valves are starting to wear out sooner than this, you may need to replace them more frequently. If you have any questions about how often to replace your duck valves, consult with your pump’s manufacturer or a healthcare professional.

Valve membranes

Valve membranes are located between the pump and the flange, and they help to regulate the flow of milk.

Valve membranes should be replaced every two to four weeks, or whenever they become damaged or worn. Replacing valve membranes on a regular basis will help to ensure that the breast pump works properly and that milk is flowing smoothly.


All tubing should be replaced every few months, as they can become worn down and may contain bacteria. Breast pumps should also be cleaned after each use, as they can harbor bacteria. It is important to clean all parts of the pump, including the tubing, after each use. If you notice any cracks or wear on the tubing, it is important to replace it immediately. If you have any questions about how often to replace your breast pump tubing, please consult your healthcare provider.


The average lifespan of a breast pump diaphragm is around 18 months, although this can vary depending on the brand and model of pump. Over time, the diaphragm can begin to lose its elasticity, which can impact the pump’s performance.

In addition, the diaphragm can become cracked or damaged, which can create gaps that allow milk to leak into the pump.

For these reasons, it is important to regularly inspect the diaphragm for signs of wear and tear. If the diaphragm appears to be damaged or worn, it should be replaced with a new one.


One of the most important parts of a breast pump is the flange, which is the funnel-shaped piece that fits over the nipple. Flanges come in a variety of sizes, and it is important to find one that fits snugly but is not too tight

Most manufacturers recommend replacing flanges every few months, or sooner if they become damaged or start to show signs of wear. In addition, it is important to clean the flanges after each use, using either soap and water or a dedicated pump cleaning solution.

Backflow protectors

Backflow protectors are an important part of any breast pump. They help to prevent milk from flowing back into the pump, which can contaminate the pump and cause infection.

While most backflow protectors will last for several months, it is important to replace them on a regular basis to ensure that they are effective.

The frequency with which you should replace your backflow protector will depend on how often you use your pump. If you use your pump daily, you should replace the backflow protector every two to three months.

However, if you only use your pump occasionally, you can replace the backflow protector every six months.

By replacing your backflow protector on a regular basis, you can help to ensure that your breast pump is always operating safely and effectively.

Parts replacement frequency for famous brands:


Medela advises replacing the new breast pump parts (shown below) as needed or when damaged in their FAQ chatbot. They don’t have to be changed within a specified amount of time. (For the older parts, I would adhere to the aforementioned general principles.)


Your valves should be changed every 8 to 12 weeks if you express once daily. Every 4-6 weeks, if you express milk solely, we advise replacing the valves.


Below are  for how frequently their pump parts should be replaced:

  • Duckbills: Pumping more than 3 times per day – every 2 months / Pumping 1-3 times per day – every 3 months
  • Backflow protectors: Pumping more than 3 times per day – every 3 months / Pumping 1-3 times per day – every 6 months
  • Tubing: Replace as needed
  • Breast shields: Pumping more than 3 times per day – every 6 months / Pumping 1-3 times per day – as needed


The “expected operational life of the replacement washable components is six months,” according to the Elive instructions manual. Selling your breast pump may help you to save money on replacement components.

What is the best pumping schedule to increase supply?

It is recommended that women pump every 2-3 hours during the day and at least once overnight. This schedule provides the best chance of increasing milk supply. It is also important to pump for at least 15 minutes each time.

Women who are pumping at work may find it difficult to stick to this schedule, but it is important to pump as often as possible. If you are unable to pump as often as recommended, try to pump for longer periods of time.

Additionally, try to avoid going longer than 4 hours without pumping during the day. The best pumping schedule may vary from woman to woman, so it is important to experiment and find what works best for you.

Ultimately, the goal is to pump often enough to maintain a healthy milk supply.

How long do breast pumps last?

Most breast pumps will last for several years as long as they are properly maintained. However, it is important to note that breast pump technology is constantly evolving, so newer models may be more effective than older ones. If you are using an older model breast pump, it may be time to consider upgrading to a newer one. Additionally, if you notice that your breast pump is not working as well as it used to, it may be time for a replacement.


When to order a breast pump from insurance?

Most pregnant women order breast pumps during the 30th week of pregnancy, but you can do so whenever you like. Get started on this procedure before you enter your third trimester of pregnancy if you want to have everything ready for the birth of your baby.
