NFPA 13 - 2010 8.6.5.2.1.8 "The requirements of 8.6.5.2.1.3 shall not apply to sprinkler system piping less than 3 in. in diameter." The commentary goes on to say that sprigs or riser nipples (or offsetting the heads) are required on 3" and larger pipe. This is for SSU heads. Not only Large Drop.

Or maybe it does, it's just that I've been stuck on the '13 edition for so long I'm a bit confused going backwards. Could the V3404 be regarded as a CMSA/Large Drop? The large drop tables I'm looking at in my '07 edition show the CMSA as having specific pressure requirements, while the V3404 clearly notes it can be used for storage in an area/density method. Lots to think about. *Ken Wagoner, SET *Parsley Consulting*** *350 West 9th Avenue, Suite 206 *Escondido, California 92025 *****Phone 760-745-6181* Visit our website <http://www.parsleyconsulting.com/> *** On 9/19/2014 1:02 PM, Cliff Whitfield wrote: > Ken, > > I assumed Jay was talking about having 3" lines without sprigs to the > sprinklers.
