high pressure hydrant PRV

[cheyer]

I've been unable to locate a code or standard that would require PRV's for a 13D or 13 system with an on-site high pressure hydrant (<150 static). I have a very large residence that this happened to be missed originally, and we are trying to find something with teeth on it in order to get one installed.

Any thoughts/suggestions?

Thanks.

Happy Thanksgiving

You could require it per the max pressure the pipe and heads are rated to??

I think 175 psi?

no flow test done for plan submital???

what does the sprinkler company say???

In 2010 Edition I believe it’s in:

Definition in Chapter 3 “Private Water Supply Piping Definitions”

Code text in 6.7, 8.16.1.2 and in acceptance testing provisions
