I was always told to leave them all dripping. That’s what we ask our renters to do during below freezing nights.
It works, sometimes
I only leave the outside ones dripping but here it rarely gets below 16 F.
Depends a lot if the piping is in an outside wall.
I am imagining that it would take more than a drip to stop pipes from freezing.
I leave 1-2 dripping PLUS the toilet. They do not flow unless used. So either use it every couple of hours or open the tank and adjust the valve so it dribbles just like I do. I failed to do that 2 years ago and blasted apart every pipe I had in an out building.
All of them, especially the lowest tap.
Be especially careful of pipes that run along exterior walls.
I just crank my furnace up to 85 degrees.
Doing my part for global warming!
I also open doors under sink so warm air from room gets in there. Not sure if it helps much, but it seems like it could a bit.
...pipes that are exposed need insulation (garages ) and weather strip your garage doors
If you live where it freezes why isn’t your house properly insulated? Mine was when I lived in Texas and it rarely froze there
yes, leave dripping.
need to grab some pipe insulation tomorrow from the hardware store (if there’s any left)
Cold here in SoCal tonight. It’s just a little over 60 degrees.
Sorry, I couldn’t resist.
Let all near outer walls drip.
Open cabinets under each sink to allow heat in.
Depending on how many faucetts you have, let them all drip when temps fall into the teen or lower. It is better to pay a few $$$ more on the water bill than to have major plumbing due to burst pipes.
Run them all at a flow almost the diameter of a # 2 pencil. The cost of that much water is a tiny tiny fraction of a plumbing repair.
If you have lavatories on external walls open the vanity doors, unless you have extremely well insulated walls.
Several years ago, an acquaintance only ran their kitchen sink. The master bath lav was on an exterior wall. The pipe inside the vanity, from the shutoff to the faucet froze and broke and leaked all night long. The low was 22.
Better safe than flooded and sorry.
Niagara Falls either froze completely or mostly.
I do not think a dribble of water would be enough for your pipes. Drain them if they are in danger of freezing.
Get some insulation and if needed electric tape to warm the pipe above freezing.
Turn off the water at the meter and drain all the water out of the pipes.
Crank up the heat, open cabinet doors under each sink, slow drip every faucet indoors, put a insulated cover on outdoor spigots and or at some point install freeze proof type spigots. Consider adding heat tape wrap under pipe insulation cover that turns on at 31 degrees automatically to every section of water line you can get access to.... Install a wood stove and secure about 10 cords of hickory as well. Electricity goes out you will be very happy to have that wood stove .
Second ice age is on the way ....:o)
