Thanks for the insight. This stuff really is PVC (marked "PVC" on the
outside). The interesting part is when I was sanding some PVC water pipe
completely through, I found that there appears to be a liner in the pipe
designed for potable water. There is a thin layer of more flexible, and
stronger plastic, on the inside of the pipe.
