nfpa 13 d water requirements
(OP)
went to a house to inspect the fire sprinklers for insurance reasons system had no calc tag and 52psi at the base of the riser and flowed forty psi at the main drain. No room had more then 1 head in it and system was looped from city supply. does system have enough water and is a loop system legal in 13d cant find any thing in 13d 2007





RE: nfpa 13 d water requirements
No way to know if there is enough flow/pressure without a lot more information.
elevation
k-factor of sprinkler
water meter size
lead-in size
backflow preventer?
diameter / lengths of piping
etc....

Is there a remote insp test connection? If so, do a bucket test. That will give you a good idea of what is available and if the system works or not.

If you can draw it out, you can calc it

With current programs, it is not really all that hard. Even doing a loop calc by hand is not overly difficult, especially when it is only 1 head flowing.

I hope that was helpful.
RE: nfpa 13 d water requirements
And the owner or insurance company wants you to say system is good to go
Sounds like I would put it back on the owner / insurance co to hire someone to prove ip the system
I would not put my name on it, being an inspector also
