No, I know the difference between ABS and PVC. ;)
This is black Schedule 40. It is stamped on the side.
I saw 4" and 2" sizes, with some slotted 4" to boot.
Maybe it's only available around here--many houses are
built on pilings to survive storm surge, and exposed,
white PVC plumbing looks awful on a half-a-million
vacation dream home.
I was in the planning stages of building a waterfall
for the pond, and needed something to carry the water
from the filter outfall to the waterfall's basin. I
ended up using grey polybutylene because it was
flexible and would have less friction head.
