If you're still concerned about pressure you can get higher pressure rated
sprinkler heads as well for a minor extra cost. I believe Reliable has most
of their sprinklers rated to 250 PSI now? (Double check that)

what is the failure rate of SR heads at 50 years and 75 years? 1 % or 95% ?

Sorry, my last words.
Some of you have concluded its pressure. What does replacing them all do to fix
the pressure.
Some of you have concluded age.
Others creep.

How do you get a building built in 67 that needs a 50 year test in 4 years when
it is already 51 years old. Maybe it’s just time to change the heads.

To me this sounds like classic Solder creep. The solder softens furring
warm conditions, and after many many (years) of hot days, you start to have
heads pop as the solder has finally given in to the pressure it has been
holding back. I think your correction on this would be glass bulb

165 F sprinklers at the roof of a warehouse, this would normally require 200 F
