Also, if you are removing the head for an "inspection" inside the fitting, you are performing tasks per 25, and must supply a new sprinkler.

Can you live without them? -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of John O'Connor Sent: Thursday, February 28, 2013 1:44 PM To: [email protected] Subject: RE: Bedbugs Gentlemen: Paragraph 6.2.1 (2007 Ed. NFPA-13) states: "Only new sprinklers shall be installed." This refers to new work. We relocate sprinklers in office environments all the time. Where does it say specifically that if you unscrew and remove a head, you replace it? What about general maintenance such as internal inspections, where one head is to be removed for a visual inspection inside the fitting? You infer that the only correct action is replacing every head you ever remove. I say you are reading more into the code than intended. If they wanted only new heads for every action, they (the committee) would have said so. Reference also the 2002 edition of the Automatic Sprinkler Handbook, page 106, para 6.1.2.2 where they discuss reconditioned components. "However, when sprinklers have been installed in a building on a temporary basis--for example, prior to finish ceiling work--the same sprinklers can be used on that job. The same holds true for an existing system that is being lowered to accommodate a new ceiling provided the sprinklers are of the proper orientation and the associated hazard has not changed." The committee has clearly allowed relocated heads to be used. If the occupancy has not changed, the original head, as in the case of the bed-bug remediation example, can be reused. Obvious exceptions are if the head(s) are 50 years or older, or of the wrong orifice, temp, thread size etc, precluding its applicability as a suitable head for reinstallation.
