Check Your Tubing at the Faceplate Connectors
Ensure that the tubing is properly attached to the nozzles on the Medela Pump in Style Faceplate. If the tubing is loose your breast pump might not be getting the proper amount of suction in order to work properly. Try adjusting the tubing to ensure that it is properly attached to the faceplate. Sometimes the tubing will come lose a little bit without you even realizing it. This solved over 75% of suction issues that I had with my Medela Pump in Style breast pump. I used my breast pump several times during the day while at work.
Carefully inspect the tubing for your medela breast pump and make sure that there isn’t any visible cracks or holes. If your tubing has visible cracks, you will need to order replacement tubing. I always kept an extra set of tubing in my breast pump bag, in care I had any problems with my tubing. The tubing can’t be purchased at local retail stores including popular baby stores. The only place that you can find replacement tubing by contacting Medela directly or by ordering it from my website below. (I do make a small commission if your order products listed on this page). If you don’t have replacement tubing for your breast pump on hand you will be unable to use your breast pump for a few days until you you can get your replacement tubing.
Inspect the Membranes
The membranes are the white plastic flaps. They are attached to the breast pump valves. The membranes are responsible for creating enough suction for expressing breast milk. If the membranes are damaged in any way, it will cause your breast pump to lose suction. You may also notice that you are only able to pump a fraction of the breast milk that you usually get from your breasts. Inspect the membrane for tears. If the membrane is torn you will need to replace it immediately. In fact, Medela membranes should be replaced every few weeks.
Inspect the Valves
The valves are the yellow pieces that attach to the bottom of the flanges (the clear plastic pieces that look similar to a funnel). The valves are pretty easy to damage, especially, when you trying to get the valves off so that you can wash them. If your valve seems to be stuck, I found that twisting it helped me get the valves off the bottom of the flange easier. There was several times that I accidentally cracked the bottom piece on the very tip of the valve. When you attempt to use your breast pump with a cracked valve, even a small one, chances are you will notice that you are no longer able to pump nearly as much milk or you may notice that your pump suddenly makes a different sound (I had this happen and it sounded like their was air escaping). A cracked valve will cause the membrane not to function properly. Replace the damaged valves immediately with replacement Medela Valves and Membranes kit.
Remove the Faceplate and Inspect Diaphragm
To check the diaphram on your Medela Breast Pump you will want to remove the tubing and AC adapter. Then you will carefully pull the faceplate off. Once the faceplace has been removed, then inspect the diaphragm (it is a white piece of rubber that moves back and forth when the motor is running). Carefully check the diaphragm to make sure that it doesn’t have any visible cracks, tears, or appears to be damaged. If the diaphragm is damaged, please contact Medela directly for further support.
I hope you were able to figure out the problem for reduced suction in your Medela breast pump.
