Absolutely correct ! Interestingly despite all the verbal claims by contractors the requested documentation is rarely produced and the proposal soon abandoned.
Its like being in line for parachutes, no one wants to be at the end of the line.

In situations like this, I look at it from a lawyer's perspective - what was the basis for the decision to apply the product this way? If the tech data sheet is mute, I always contact the manufacturer directly and ask if they'll warranty the application in writing or furnish an engineered judgment on their titleblock or letterhead. That usually gets to the bottom line pretty quickly ...

In other words, don't look at the absence of a restriction in the listing and conclude that "it must be ok". The listing agency does a series of tests/evaluations based on requirements in the applicable standard (NFPA 13 in this case). Unfortunately, if NFPA 13 is ambiguous or doesn't address the arrangement, the listing agency covers by making a blanket requirement such as "must comply with the manufacturers installation instructions and NFPA 13". This passes the buck back to the standard and THE AUTHORITY HAVING JURISDICTION. So, if you ever hear someone state, "It's OK!! It's listed!!!", think twice and ask, "Listed for what? What tests were conducted that prove it's OK to do this?" J.

Is there any restriction on this? Could the bending of the flexhead potentially put some weird forces on the CPVC pipe and glued fittings that could cause a problem? They claim they do it all of the time, but I've never seen it. Todd G.
