Re: Leadpipe Crud

First -- To address a "pet-peeve" of mine ... it's "leaderpipe" or "mouthpipe" or just plain "pipe"; not "leadpipe". Long explanation, but "leadpipe" is incorrect. It's in the vernacular, sadly, so I doubt many will self-correct (?).

One area that seems to develop red-rot early, is exactly in the area where the pipe-to-valve cluster brace is soldered, (or more correctly, the brace-flange).

I have seen this. It occurs because the heat from the soldering process causes the zinc in the brass-alloy to "leach", and come to the surface (inner-most) of the mouthpipe. Saliva and moisture (condensation) "compound-the-felony", and the process accelerates to manifest itself. Result: the dreaded "red-rot".
