Is there any reference on the internet about temperatures and durations
that
are required to freeze pipes?

Every year I get neurotic when they start having frost advisories about my
cottage. I know it takes hours to freeze ice cubes at 0 degrees, so it
obviously takes more than a few hours at 30 degrees to freeze pipes; but
some actual data would be nice.

It is a big chore to shut off the water, and then I am without water until
next Spring.


Other posts have good comments. If you can't or don't want to handle it
yourself then have a plumber do it--at least for the first time. If the
house is left unoccupied and unheated for (I think) 30 days and something
happens you might have an issue with the insurance company. If you're in an
a location where below 30 is not a frequent occurrence then why not leave
your thermostat at 50 deg or so and have complete peace of mind.
