Hello Everybody,
Merry Christmas from Pittsburgh, PA

It is getting cold here! And I just started a new job with a company
that
does plumbing, heating, and cooling (I am not the plumber for I studied
the
heating and cooling and refrigeration)

Big question!
When the outside temps cause the various inside pipes to freeze and there
are
both hot and cold pipes that have similar exposure, is the hot pipe going
to
freeze first?
