Good morning, All:
Just received my "Sprinkler Quarterly" Magazine that addressed this specific issue - can't say where exactly NFPA-13 says, but NFSA addressed this issue by stating: Replace sprinkler if it has been removed from fitting (RC, tee, el, etc.). If drop nipple is removed and sprinkler stays in fitting, the sprinkler does not require replacement with new head. Regards to all- Jerry [email protected] Jerry D.

The pendant heads are fed on swing joints. My plan is to have them removes the drops (with sprinkler in them) replace the 1" elbow with a tee and re-install the drops. The question came up about replacing the pendant heads. They were not removed from the pipe but the pipe with head was removed from the system. I never thought about this before and can see arguments on both sides. Replace the pendants or not?
