Buff:
Please keep us advised; I believe it's probably a more common problem 
than is recognized.  I'm beginning to think that, if there was a method 
that wasn't too difficult to use, that folks would clean their pipes 
more often, like about once a year, if the pipe had to come off anyway, 
why not check/clean it?  I know I sure would.
