No extra calcs required. The spray radius is there. I recently replaced an activated head that had thrown water@ 5'-0" over 15 foot from the head. 65 psi.

Expanding a little more on the 9'rule in light hazard,
The pressure has to be there inorder to deliver the gpm needed for the max working area of the head, so going beyond the 7.5' is doable but not without research first.

Agree?

So a guy told me that there is a 9' rule in light ordinary hazard, and he explains it as the head can be 9' from any wall. The occupancy is massage parlor and commodity is light ordinary hazard.
-any comments?

Yes. Bleed it down below 175#. That is the normal max operating pressure for most sprinklers. You need a pressure relief valve if not an antifreeze system. You should have an expansion tank if it is an a/f system.

Pick your brain question. What does FBC stand for in fbc compliance?

If you haven't noticed with the questions, we are doing a large hybrid project so I will be picking CPVC brains
