I guess it's a good thing the sun doesn't shine in Florida because
most people with a well have pipes outside and they are always white
PVC. Explodig pipe is not a huge problem.
Yeah, all the well pipes here are underground. It's the altitude for us
that does it. At 5800 ft above sea level, the sun is pretty intense.
That's why a number of folks refer to Albuquerque as the "skin cancer
capital of the world". I've lived in a number of places, travelled to
many others, and have never felt the sun more intense than it is here.
With that comes extreme dryness as well so that may be playing a part in
the plastic's demise as well.

Naw, PVC is broken down by UV exposure. You are probably right, at 5800
feet the amount of UV reaching the pipe is much more than it is at sea
level - anyone who mountain climbs knows this. I've got 2nd degree burns
from not respecting how much more UV exposure you get at the top of even a
moderately tall mountain.

It's my limited understanding that the PVC is worn out by the UV radiation
reacting with the chlorine in the pipe - something that CPVC as much of due
to how it's processed. But I think all plastic is harmed by UV radiation, I
know that PEX is, PVC certainly is, nylon not so much, and I'm sure a few
others.

Simple solution. Put all plastic pipe inside of copper pipe, use the
next size up in the copper. Like 1/2" cpvc inside 3/4" copper.
Oh, wait a minute, soldering the copper would melt the cpvc. You have
to use steel pipe instead.

You're a hoot! But why would you solder the copper
pipe?

Why to keep all those dangerouse emissions the CPVC puts out from
escaping of course.
