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?


Hmm...I don't know what the scientific answer is going to be but last
year we had a burst and *both* the hot *and* cold pipes split in almost
the same places (they were side by side). These pipes ran along an
outside wall and ran to the washer hook-up. We had only been living in
the house for 2 weeks when they burst and I didn't know where the shut
off valve was. Water was jetting up from the splits, hitting the roof
and coming down again like a waterfall! At first I thought it was the
upstairs neighbour who had the leak until I plunged under the waterfall
to discover the splits in both pipes.

I found the hot water shut off close to the hot water tank but the cold
water eluded me for a while and finally I had to call the landlord and
ask him where it was. It turned out to be located under a false 'floor'
in the bathroom 'cupboard'! By the time I got the cold water shut off we
had 2-3" of water on the floor.

So from my experience they can both go at the same time...lol.
