NFPA 13-2019 vs 2016 Revamping of Hydraulic Design Systems

NFPA 13-2019 vs 2016 Revamping of Hydraulic Design Systems


In NFPA 13-2016 in clause A. It is not the intent of this section to require a full hydraulic analysis of the existing piping system in addition to new sprinkler layout.


But I could not find this clause in NFPA 13-2019 in clause 29.5.2


Does it mean every time, we have to do a full hydraulic cal?


Thank you
