You have your pump, you have your routine, and then one day suction just is not what it used to be. Before you assume it is a supply problem or shell out for new parts, take heart: worn parts are the most common culprit, and many insurance plans help cover replacements at little to no cost. This guide walks you through what wears out, how often, and exactly how to order fresh parts through your insurance.
What You Can Usually Replace Through Insurance
Most plans that cover breast pumps also cover replacement parts, though how often varies. Here is what typically qualifies:
Duckbill valves and membranes (the small silicone pieces that create suction). Backflow protectors and diaphragms. Breast shields, also called flanges. Tubing (for traditional pumps). Collection bottles. Coverage frequency depends on your plan: some allow replacement parts monthly, others quarterly or annually. Under the Affordable Care Act, most plans must cover breastfeeding equipment, though the specifics of parts coverage are left to each insurer.
When to Replace Each Part
Knowing the general timelines helps you order before performance drops, not after.
The silicone pieces wear out fastest because they flex thousands of times per session. Duckbill valves and membranes often need replacing every few weeks if you pump several times a day, or every couple of months for lighter use. Backflow protectors and diaphragms typically last a few months, while harder plastic flanges and bottles can last around six months. A quick test for a duckbill valve: when the pump is off, the slit at the tip should stay closed. If you see a gap at rest, or if the silicone looks thin, stretched, or torn, it is time for a new one.
Why it matters: worn valves and membranes are the number one reason pumps lose suction, and a weaker pull means longer sessions and, over time, can affect your supply. Replacing small parts on schedule keeps your pump working like new and protects your milk output. It is also better for hygiene, since silicone that has cracked or clouded cannot always be fully cleaned. For help confirming your flange size before reordering, see Storkpump's flange sizing guide, since your size can change over your journey.
How to Order Replacement Parts, Step by Step
The process is more straightforward than it sounds, especially with a durable medical equipment (DME) supplier handling the insurance side.
First, check your coverage. You can call your insurance directly and ask whether replacement valves, membranes, flanges, and tubing are covered and how often, or let a DME supplier verify it for you. Next, confirm which parts you need and match them to your exact pump brand and model, since parts are not universal. Then place your order through an accredited DME supplier, which is required for insurance-covered supplies. Many suppliers, including Storkpump, can bill your insurance directly and ship the parts to you, so you get them at little to no out-of-pocket cost. A good habit worth adopting: keep at least one spare set of parts on hand so a sudden break never interrupts your pumping schedule. Many parents keep one set at home and one in a work or travel bag.
Why It Is Worth the Effort
Out of pocket, replacement parts can add up to anywhere from around fifty to several hundred dollars over a year of pumping. Using your insurance benefit means that cost can be largely or fully covered, which is real money back in your pocket during an already expensive season of life. Beyond the savings, staying stocked with fresh parts keeps your pump reliable and your sessions efficient, so you spend less time pumping and more time with your baby.

Frequently Asked Questions About Breast Pump Parts Through Insurance
How often will insurance cover replacement parts?
It varies by plan. Some plans cover replacement parts as often as once a month, while others allow them quarterly or annually. The best way to know is to have your supplier check your specific benefits, which Storkpump can do for you.
Do I need a prescription to get replacement parts?
Some plans require a prescription or letter of medical necessity for replacement supplies, and some do not. Your DME supplier can tell you what your plan needs and, in many cases, help obtain the prescription for you.
Can I get parts for a pump I did not buy through insurance?
Often yes, as long as your plan covers replacement supplies for your pump's brand and model. You will still need to order through an accredited DME supplier. Reach out with your pump details and your supplier can verify eligibility.
How do I know which parts I need?
Match the parts to your exact pump brand and model, since components are not interchangeable between pumps. If you are unsure, note your pump's model and the parts that seem worn (usually valves or membranes first), and your supplier can help you identify the right replacements.
Why keep a spare set of parts?
A backup set means you are never stuck if a part breaks or wears out sooner than expected. Many parents keep one set at home and another in a work or travel bag, which also makes cleaning easier since you can rotate sets.
