I’ve seen the forecast. The cold is going to get as far south as Pensacola. I’m going to be blasting my heat in my house to keep pipes in the crawl space from freezing. As a last resort, I could simply shut the water valve off overnight on a few nights and run the taps dry, then turn it on again when the temp goes back up the next day. No water, no burst pipes.
The cold get much further south than Pensacola. As far as freezing pipes: I doubt you’ll have a problem as long as you drip the faucets.
Unless your pipes aren’t insulated at all, a freeze won’t usually reach into the pipes terribly. We don’t worry about ours until it gets to the low teens. We have one spot in our basement where it’s pretty exposed, and it has been a problem twice. We run a blow dryer pointed directly at the spot when the temps get that low. Haven’t had a new problem yet, and it’s been 7 or 8 years now with no burst pipes. The trick of letting the water drip helps too, but adds to the water bill. Still, a higher water bill is preferable to the cost and trauma of burst pipes.
Another idea is to open your cabinet doors in the kitchen and bathroom so that they get ambient warmer air in there. Of course, if you have kids or pets, that might not be a great option.
