Subject: RE: Attic Piping
Good morning Brian,
Your fitters will hate you if they have to set the main high towards the ridge.
The best way is to use a single main, hung low, with 1" or 1-1/4" sprigs to the
back to back sprinklers at the ridge. If you have a mechanical chase that
extends in to the attic, you may have to be below that to make sure everything
can drain. If you can coordinate with the attic catwalk, you want it to be
offset of center and you'll hang your main on the side that the catwalk is not
located. Be sure to "restrain" your sprigs as they will be over 4 feet.

I typically use option 2. Sometimes the framing at the peak can be a little
funky and it is easier to adjust a smaller line. Also, I will put 1” outlets on
any welded pipe for attic sprinklers, in case sprigs become necessary.
