re: Remember to drip yo water bruh. Wind chill of 2 degrees tonight.

Nope. It's the major benefit. The water coming into the house is much warmer than freezing because it's in the ground. Keeping that warm(er) water in your pipes is what stops them from freezing and busting. You can't relieve the pressure of ice.

Insurance Institute for Business & Home Safety says otherwise:

Letting a faucet drip during extreme cold weather can prevent a pipe from bursting. It’s not that a small flow of water prevents freezing; this helps, but water can freeze even with a slow flow. Rather, opening a faucet will provide relief from the excessive
pressure that builds between the faucet and the ice blockage when freezing occurs. If there is no excessive water pressure, there is no burst pipe, even if the water inside the pipe freezes.
A dripping faucet wastes some water, so only pipes vulnerable
to freezing (ones that run through an unheated or unprotected space) should be left with the water flowing. The drip can be very slight. Even the slowest drip at normal pressure will provide pressure relief when needed. Where both hot and cold lines serve a spigot, make sure each one contributes to the drip,
since both are subjected to freezing. If the dripping stops, leave the faucet(s) open, since a pipe may have frozen and will still need pressure relief

How are they separate? Running hot runs the hot water line.running hot runs the cold water line by having the heater draw in more cold water.

Will leaving a drip on the hot water side damage my tankless heater?

I have an electric tankless in the attic, so in order to drip the hot water line without engaging the electricity and having the elements heating for hours on end, I yank the ac disconnect pullout in the service box located in my laundry room. I normally do this before bedtime and then plug the pullout back in the next morning when I need hot water again. It’s a little inconvenient, but it beats having that line in the attic bursting.

Nah, but it helps.

Thanks for educating people. For all those saying wind chill doesn't matter, you better bet your arse that wind will increase the rate of heat transfer and it does matter. Do any of y'all even "heat transfer" bro? I'm old, but I think that's the way to do that, right?

The cabin I go to in Vermont just drips the cold water, and that place deals with 0 degrees regularly. If you have the heat on in your house, I really think this seems silly down here. If anything, I could maybe see dripping the outside bibs.

You do realize they build things differently in Vermont right?

Shouldn't you turn on both?

Not at my house. Cold only. Hot is a waste. The freeze of my pipes occurs outside, never inside.

It has nothing to do with preventing freezing as the main goal and everything to do with preventing bursting if freezing happens.

Science is hard.

It is for you

Let me help you out. Dripping the water will reduce the chances that your pipes freeze by constantly replacing the water in the pipe. T chnically the temperature needed to freeze your pipes should be lower with a dripping faucet. However, if the temperature drops low enough the pipe will freeze regardless. This is where the open system of a drippping pipe is beneficial.

I've found another good thing to do is I program the dishwasher to run at some point in the middle of the night.

I drip the pipes as well.

Never had any issues.

Depends on the design of your plumbing system. Maybe you have mulitple lines coming in from the outside, or lines in the attic.
