Okay, I have the pod out, and hoping to save the 50 bucks for a new pod, I transplanted the rubber diaphragm from my new center vent pod (turns out the center vent pod was fine) and it now works. Is there some way that I could get rubber diaphragms that would fit these without having to buy the whole pod? I remember seeing somewhere that people were getting them from a vacuum repair kit or something along those lines, although I can't be sure.
