I am working on a project where we have to add heads above an existing ceiling on an existing system. 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?
