No Hyd Pressure Change to System - Code
No Hyd Pressure Change to System - Code
(OP)
I am designing a system and there is no hyd change to the system that I am adding to. I would like to know the code that I can list on my drawing to state that this system has no change in the system. Any help would be much appreciated.

I was wanting to put the code on my sheet that has the number for this.
Any idea?
I appreciate the help.

Are the branch lines being added, adding to the remote distance? If so, hydraulic calcs are in order. This then becomes the same as a full new system submittal in a sense. In any case, the items outlined in NFPA #13 must be accounted for in your drawing. Reference Chapter 22, section 22.1.3.
