Subject: RE: standpipes

 

By definition, a “Branch Line” is piping that connects a single hose
connection to a standpipe.  Per NFPA 14, §7.6.3, branch piping shall be
based on the hydraulic criteria of §7.8 but not smaller than 2½”.  Since
you’re at the base of a standpipe and not near the presumed remote area, I’d
say it’s likely that 2½” is adequate.

 

The foregoing is my opinion only and is not intended to represent the NFPA
14 Technical Committee, nor serve as an interpretation of the standard.

Subject: standpipes

 

I have a situation where my 6” standpipe is coming into stairwell @  16’ AFF
can I drop down 11’ (to get to my max 5 AFF)  with 2.5” to feed the hose
valve on the 1st floor or does it need to drop down  6” with a 2.5” outlet? 

 

 

Thanks in advance Mr. Leyton for your assistance J
