AFPsprink.com -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of David Bitton Sent: Tuesday, June 22, 2010 3:37 PM To: 'Sprinkler Forum' Subject: Rebuilidng a sprinkler system after a partial roof collapse Hello all, A 14,000 sq. ft. section of a large warehouse collapsed, bringing down some sprinkler piping that will need to be replaced. I am concerned that the operating elements on the remaining sprinkler heads have been weakened by the pipe movement during the collapse and would fail once we do the hydrostatic test on the system, causing water damage to the stock. Are there any guidelines for determining whether the remaining heads need to be replaced? (A visual inspection revealed no apparent damage to these heads.) Thanks, David Bitton, Eng.
