    It's not a closed system, so BM can certainly get into it. If you are talking about large volumes of BM, you'd see that the tubes filled with milk. I overfilled a bottle once and got milk into the tubes and behind the cover plate. If I remember correctly it didn't seem it would get back behind the membrane on the pump itself. You can try popping off the cover plate to take a look.

    No you don't have to replace. Pop off the cover, you will see a white round thing. Wipe it off and the surrounding area.

    Check your manual, I think there are directions on how to clean it. I did that to the Medela Swing and there were instructions.
