Terrible logic/incident relationship.

I don't disagree, but water incidents can happen anywhere, anytime and SUCK.

Yes, it most definitely can happen anywhere. But the impact and size of damages are far less when you have a shorter building.
 
I've had some insurance reviews after water breaks in shorter towers. If not caught quickly they still add up. Had one pex line that cracked. was more than 2 mill damage when found.

However depending on what broke could add to the cost, especially if it was a glycol line. But I seem to remember the most above 28 is cooling plant and domestic water storage. If it was a feed for the upper mech room on 69 then we have a large volume.

Pex is susceptible to cracking?

it is particularly sensitive to sunlight/UV with potential exposure and deterioration pre as well as post construction; to various chlorine/chloraminr solutions (particularly at higher concentrations and moreso in combination with hot water); to repeated exposure to freezing; and joints are susceptible to damage from “water hammering”.

I don’t know if that qualifies PEX as being “susceptible to cracking” but it certainly isn’t immune to cracking.

Yes it does crack. There was a service bulletin out some years back as well as a lawsuit or 2. The other, Aqatherm piping is also susceptible. They both have to be installed at specific temperatures. I only found this out when we were lookin at why we had some failures on some systems a few years later. PEX did change the chemistry to deal with some of the issues, but if the installers do not follow procedures things happen.
 
Thanks @Airboy this aligns with a recent restaurant I was involved with on the Design side of things. The owner hired a lawyer to sue and of course I got involved. A hot water line (PEX) split near the under-counter shut off valve. I took pictures and forwarded same to the owner's lawyer -- the plumber installed the line with a hard bend and -- fortunately -- I forewarned the plumber before the Final Inspection, suggesting (in writing) that there could be future problems. When a leak developed the plumber blamed it on PEX whereas the owner looked for proof of a poor installation. I have since been collecting (where I can) others' experiences. I have not lost faith in PEX -- I believe that it is still superior to copper if installed correctly and it is certainly an easier install from a labor perspective. I wonder what the issue was for Stantec tower.
