My whole family will be out of town for three weeks. I plan to turn

Why bother? What is your objective?

I turn mine off if the house will be empty for more than
a week. I turn off the gas to save money (and as an extreme
safety measure). I turn off the water in case of a leaks.

Water leaks do happen spontaneously, and often. Having
said that, by far the most common cause is the failure
of the flexible hoses to washing machines and dish
washers. I've installed high quality flex hoses and
so my risk is greatly reduced. But it takes 30 seconds
to turn the entire water supply to the house off and
I'd rather do that than face a small risk of major
damage and a serious cleanup project.

Although I turn off the water supply to my house, I
have it arranged so the sprinkers can remain on.
That's critical for a long summer vacation unless I
want to return home to a dead lawn and plants.

I leave the power on but disconnect most outlets
except for the fridge/freezers and security lights.
