Hi,

Please refer below snap shot from NFPA 13.

Question 01

We are designing for wet sprinkler system Ordinary hazard. After 275 sprinkler the below table sating 200 mm diameter pipe.Section 8.2 not mentioned about pipe size. Could you please clarify.

 

Question 02

I have provided every 275 sprinkler one ZCV for wet sprinkler system. Though wet sprinkler system (275 -1 ZCV) it is not a mandatory but i feel maintenance point of view this will be good practice. Please suggest.

 

Regards,

Nirmal
