Running water at night when temperatures are below freezing

1.24K 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?

You should trickle it during the day if it’s cold enough , specifically the kitchen sink …. It’s always the god damn kitchen sink that freezes .

In cold climates we don’t put any piping in exterior walls but things close to the exterior walls are susceptible . Especially when there’s gaps and cracks in your building envelope.

I always make sure my home is ready for the extreme cold snaps but it amazes me how many people do nothing ( have to do a bunch of unthawing at my mom’s every god damn year and replace her frost free hose bibs …. Every fucking year ) but water is cheap and plumbers are expensive so just dribble your faucet .

Also check your furnace vents for ice build up if you have side wall venting on a high efficiency furnace
