If you grew up in the North and move South you may be in for a surprise. We never dealt with freezing pipes growing up in Chicago but houses were built with only 1 “wet wall” and that was in the center of the house, with the water line coming in from the basement.

I’ve frozen my pipes in Baton Rouge in far less harsh of a freeze, but the incoming water line is external to the house, and I have 3 separate wet walls, 2 of which are external.

Foam insulating the purely external piping works for sub freezing dips of 12 hours or less, but I’ll do a faucet drip if we’re looking at longer than that.

As a plumber I can add a few things to note for future use.

1. Let the cold water drip, but Not the hot, hot water molecules are excited and expand making then easier to freeze.

2. It costs more to let the hot water run and the risk for freezing is higher.

3. If it's a slab house the cold water just needs to barely trickle at opposing ends if the house.

4. If the house is off the ground the cold water needs to run higher than a drizzle at opposing end of the house due to pipes being exposed.

5. Pipe insulation only buy a few hours of time. Pipes can and will still freeze if exposed over long periods.



Sorry had to edit since I wasn't wearing my readers when I posted.
