"A note that may be of use: if there is still water pressure (not clear if that's the case), one way to prevent freezing is to let your taps drip/run slowly. It takes an extra amount of cold to freeze moving water."

I had to think this through... If I am without power, I am without (well) water. So I guess the flip side would be to open all the faucets, and intentionally bleed the water out of my lines, ending at the basement (lowest) watervalve...Does this sound correct?

As a follow up, this should be simple but now I don't know...
How do I determine which pipes are most prone to turn to frozen pipes? Assuming a well insulted house, I am guessing my basement holds temp above freezing longest..

Anyone have experience in this? I think I just added my handheld Fiske temperature reader to potential "emergency tool shed" status.
