In Nashville two weeks ago the installation committee voted that if the sprinkler wasn't removed from the fitting it was installed into and was handled with care, then it could be reused (Remove the drop). Also, a dry sprinkler can be removed and then reinstalled provided the wrench was used on the barrel and not the sprinkler. However this has not been balloted officially so it could change. You will be able to submit comments on this matter next spring during the comment stage.
My opinion only and not that of NFPA.

It just seems like a waste to throw a 20 dollar head away because you have to remove and reinstall.....or even a 3 dollar head. We WILL comply with code, but I strongly disagree.
