Just a reminder that it is cheap insurance, with weather this cold, to turn a faucet on to a drip if you will be away for more than a day or two. If you lose power it will keep your pipes from freezing and bursting.

The best faucet to turn on is the one that is the highest and furthest away from where the water supply enters your house. So if the water supply enters your basement on the east side of your house, turn the faucet on in the westernmost upstairs bathroom.
