This will be an interesting discussion. Could it be that since fire would be expected from below, uprights are not permitted? Or is it simply an oversight since there are so few residential upright sprinklers available? Or is it that the piping would generally be expected to be installed high and one wouldn't use uprights? I don't know but am curious to see where this goes. Definitely a question for the CPVC manufacturers though.

I don't see an option for using residential upright sprinkler on exposed CPVC pipe in any of the manufactures installation manuals. Am I missing something or is QR uprights my only option?
