Running water at night when temperatures are below freezing

1.41K viewsOtherPhysics

I’ve been told to run the faucet furthest from the water meter at a slow trickle at night to prevent the pipes in our two story home from freezing (it’s about 5 degrees F where I am). Why do they recommend doing this at night only and not during the day—for example, when you’re away at work? If the temperature is below freezing both periods what is the difference? Wouldn’t you want to do this day and night?

I’ve lived in Ohio, Michigan, Wyoming (brrrrr) and Louisiana. The first I ever heard of dripping faucets was when I moved to Texas, where I live now. Texans can find a way to screw up anything*.

*Case in point. It got slightly cold today. The power went out. It’s back on now, but I hoping for no repeat of 2021.
