I plan on installing some water to feed my garden later this summer. I was considering PVC, but is this a better case for metal? How does the plastic handle the UV from the sun? I thought outdoor might be gray PVC, but I was thinking underground PVC with galvanized above.

I felt like I had to interrupt my wife's reading to show her this just because I knew she would understand. I recognize I am the problem here.
