You can also look at the ROP / ROC to see why proposals were submitted
and the technical committee substantiation (NFPA web site under list
of standards). Pitch was indeed the primary driver.

It seems as if you are right that "alignment" was removed in the
2008 edt. due to it seeming to call for the inspector to be checking
for installation errors, i.e. improper pitch. From 2008 handbook:
"Note that installation issues such as piping pitch are not covered
by the annual inspection required by 5.2.2."

Subject: RE: misalignment question 2
OK now the plot thickens, Does anyone know why this word was put in
the code and why it was taken out in the 2008 edition of NFPA 25?
( did it have anything to do with appearing to refer to pitch of
pipe?)

Subject: misalignment question
Would anyone please give an example of what a misalignment of the
sprinkler pipe would mean as far as nfpa 25 2002 edition 5.2.2.1
Thanks
