David-

The diaphram got unseated and I could not get the face unscrewed 
underwater to fix it. When I got to the surface it turns out that it was 
cross-threaded by the person who rebuilt it last. But no problem, it 
finally came off and screwed down correctly and I used it on the next 
dive.

This was a lesson for me, i.e. after you get your regs rebuilt, pull the 
faceplates before you dive to make sure you can pull them underwater. It 
is also a lesson to all you poor slobs out there who bought regs you 
can't open underwater to fix/clear. Suckers.

Of course I would not have know this at all if it were not for the advice 
of that person we all love to hate, Mr. Irvine.
