If you read the commentary in the Handbook (NFPA 13-2002) under
section 6.1.2.2, that seems to open up the idea of removing and
replacing sprinklers in limited applications, to which this might
apply. Also, if you remove the sprig/drop/arm over and replace it,
but do not touch the sprinkler, would that be legal?
I wonder what the "bad experiences" have been had with reconditioned
sprinklers. What kind of reconditioning did they use?

I know what the code says but it seems wasteful to use these heads
for 24 hours and then throw them away. I got the feeling that the
profit margin on this job was pretty slim already.
As far as firewatches go, having to rely on hotel staff for this
does not make me feel confident at all. Especially when the
management wants this all done quickly and quietly.(hush-hush)

Installing intermediate temperature sprinklers seems like the most
sensible approach, but you could not reinstall them elsewhere because
they are now "used".

Subject: * Possible Spam *Bedbug Treatment
Hello group,
Several months ago I was sent to remove the (12)sprinklers from a hotel
room so that it could be heat treated for a bedbug infestation. This
process involves heating the room to over 130 degrees. My instructions
were to remove the sprinklers and replace with nipple/caps until the
next day when the sprinklers could be replaced.
I know in many cases the heating equipment is truck mounted and the
heating ducts are stretched into the unit to be treated. In this case,
the heater/blowers were all portable units. In retrospect, with all of
these appliances in this unprotected space in an occupied wing of this
hotel, this was a catastrophe waiting to happen.
1) Could I have replaced the 155* heads with intermediate temp heads?
2) Could I reuse these heads for the next bedbug job?
