I was recently on site for a boiler replacement. I asked about
the circulator, which was only a few years old. They said it was mine
for the taking, since they were replacing, but warned me bearings tend
to fail once they are removed, since air gets in. I took it. I was
thinking of drying it out, and soaking bearings in oil. I don't need
it now, since mine is new, just thought it might not hurt to have a
spare for myself or a friend. Comments?
