Getting mighty cold in central Texas. Last couple days was 80+ degrees. Got down to 40 at midnight last night and by 9:00 this morning, it was 32. Going to be 17 degrees tonight, and 15 tomorrow night. In fact, we may not get above freezing until Saturday sometime. It was a short summer.
Anyway, I went out and dutifully wrapped all our outdoor faucets; first with a bath towel, then with two inch thick foam rubber, and taped it all tight around the faucets.
But, I wonder why this keeps them from freezing. Obviously, there is no heat generated by wrapping them, and there is very little residual warmth in the faucet / pipe stub. A little residual warmth from the brick siding, but that is all. It seems to me that the bitter cold would soak through the towel and foam rubber in a few hours. Then, what good does it do to wrap them?
I know it seems to help by wrapping the faucets, but I'm not sure why. Any ideas?
