I live in a rural area in the far SW corner of AZ. In the past, with rare
long-ago exceptions, the coldest it gets is 28 or so, possibly 25 F. And

comes up.

Of course, being me, I worry about burst pipes every time it gets below 32.
Actually, how cold for how long does it have to get before pipes can get
damaged? Yes, I know about leaving the water drip but that doesn't always
seem to work - I've still had them blocked by ice early in the morning.
Then too, there's the well pump, water tank and associated plumbing,

Winter is getting close. It's down to the low 90s during the day.g Worth
getting exposed pipes insulated? I suspect that would be expensive. At my
age - 79 - I can't do too many things myself anymore.

Needlessly worrying?

Why would it be expensive to insulate them? You would only need to
insulate whatever part is above ground. Stuff I would think plenty
good enough for AZ is a little over a buck a foot.
