Ive had a pvc supply in sun for 10 years, im suprised it still
intact, you are right not much UV will reflect up any way its
absorbed in the direct rays probably 90+%, When fabric fades from UV

Yea, I have some sections of pvc that have been outside for 15 years
now. Sprinkler lines that come out of the side of the house down near
the ground. They are in the shade from trees and bushes. They don't
show any signs of serious damage. I agree, pretty much need full
direct sunlight for any noticable uv damage on anything.

The first sign will be when you bump it and it shatters. UV basically makes the
PVC very brittle.
