I am wondering if prolonged cold spells substantially reduce the temperature
of the water entering a house from the city water service . . .

. . . and if that's true, does that temperature drop translate into
increased stress on water heaters? My neighbor's just failed and last week
we had a water main rupture, too. I can't help but wonder if these are
temperature-related failures.


I'm curious, lets say you prove that it is true. Short of moving to a
warmer climate, what do you intend to do about it? Seems like a lot of
work without much in the way of ROI.

In my case, the water in the pipes in the basement are colder than the
water entering the house. But that's because I keep my basement at
around 35 degrees in the winter. My water heater failed one summer, but
it was about 25 years old and likely due to fail anyway.
