re: Spoke to a plumber today who gave good advice on faucets for the freeze

I will gladly look at any data you have that shows the existence of a significant temperature difference between inside and outside of a cabinet that is in climate controlled air.

I just checked mine. It's 66 degrees in the kitchen and 62 degrees in the cabinet under the sink. There was a noticeable cold draft when I opened the cabinet. House is about 55 years old.

Same.

Remove the hose before the first freeze. Shut the valve in the basement. Open the spigot all the way. No brainer.

Agreed

One of my outsized spigots was froze this morning despite being covered. I just hit it with a propane torch and got it flowing before the line froze more into the house. Slab on grade and the spigot line is in an insulated wall proving yet again LNCHBOX consistently has bad takes

in the basement.

Tell me about the difference in ambient temp between the air in the kitchen and the cabinet that is located in the kitchen.

Then tell me with a straight face that difference is enough to have any effect on pipes freezing

How about someone just tells you that copper is an excellent conductor of heat. And someone else should tell you that a cold copper pipe (metal) can transfer the cold faster than the ambient temp in a room can equalize that temp to the copper pipe. And then someone else should tell you that some people are way way smarter than you and are giving out this advice to try and help dumb dumbs like yourself save money by not having to burst your pipes. I'm sure someone else could also tell you that the plumber isn't really working for the city and is pulling off this ruse to get your water bill to go up an extra $3.50 from letting it drip.

He said you do not need to drain any pipes, that's overkill and unnecessary

As someone that lives in a pier and beam home, this is not unnecessary. In the last freeze I spent all day under my house fixing pipes and was without water for 4 days. This time I chose to turn the water off and drain the pipes and blow them out. Took an hour, but hopefully it will benefit me because I don’t have to do any work after.

Your previous post was pedantic so I felt the urge to point out that "cold" can not be transferred because it does not exist. The pipe is transferring heat (energy) from the area with more heat to the area with less heat.
