Replacing parts

When should I replace pump parts?

Pumps have a lot of parts. Some are designed to last a really long time, like the pump itself and the hard plastic part that houses the motor. Others are not, because they need to be soft and stretchy to work and are therefore fragile, like the valves or backflow protectors.

Why replace parts

There are two reasons to replace your parts.

First, if you’re starting to feel less suction from your pump, the culprit is often a degraded part. All pumps have slightly different designs, but it could be a tear in the duckbill valve or just a weakness in the valve membrane. Replacing it can be a quick fix to have your pump suction back, and possibly even your milk volumes.

Second, as materials degrade, they can crack or split or get a rough surface. This can be a lovely place for bacteria to grow, but it can also leach chemicals from the material into the milk. This is why you want to check that the products you’re using on your skin or coming into contact with your milk are high quality, like medical-grade or skin-safe because they are designed, manufactured and tested so they do not leach unsafely.

When to replace parts

Each pump manufacturer will have specific information on their parts, but in general, the softer the part, the more often you have to replace it.
