Aside from sprinklers needing to be replaced due to age or damage as required by NFPA 25, sprinklers can be relocated only if the sprinkler is not removed from the fitting or outlet in which it is installed.
NFPA 13, 2016 Edition:
184.108.40.206*When a sprinkler is removed from a fitting or welded outlet, it shall not be reinstalled except as permitted by 220.127.116.11.1.
18.104.22.168.1 Dry sprinklers shall be permitted to be reinstalled when removed in accordance with the manufacturer’s installation and maintenance instructions.
I wonder if this requirement will apply to the new grooved sprinklers by Victaulic
Interesting question... However, from an AHJ point of view, I would say I would take it case by case. The fire sprinklers are not being screwed into a welded fitting, so I would want to see what the fire sprinkler manufacture has to say about the use.
At this point in time we do not have any of these in the jurisdiction I work for. But they seem to me to be a neat method with many practical uses.
I posed this question to a Victaulic representative and was informed that Victaulic is currently working with NFPA to try and have language included in the standard to specifically address the grooved (IGS) sprinkler. The grooved sprinkler was specifically designed with a unique coupling as an assembly for ease of installation and to eliminate potential damage to the sprinkler itself from conventional wrenches. It is Victaulic's opinion that if you remove the coupling holding the sprinkler, you are not removing the sprinkler from the fitting it is installed on.
An interesting example of how manufacturers work with NFPA to create and modify language for all the new fire protection technologies on the market.
