Well when I took the diaphragms out, they each had been pinched on one edge buy the cap. Guess whoever put them in last time did a sloppy job. So I removed the cap and reseated them. But there is only a small tear on the very outer edge, not on the diaphragm walls. It's torn like a 1/16 of an inch on that lip. Would that be causing that much of a problem? Didn't seem to affect it before I noticed they were pinched. New diaphragms are out of the question for me. I'll just sell this one and save for a newer model.
