The external diaphram did bulge a tiny bit when pressurized. Please excuse my ignorance, but is that a clear indication of a problem or an impending problem?

If so, is it commonly know that this is something to look for in a pre-dive check?

I had mentioned that the regulator had exhibited absolutely zero warnings of problems - but if a slight change in that external diaphram is a warning sign, then I would no longer be correct to say that there was no warning.
