Phoenix's Burton Barr Cebral Library Damaged by Sprinklers

From AZ Central an explanation and video of how the sprinkler system was set off by an atypical monsoon on Saturday.

Phoenix Fire Capt. Reda Bigler said a pipe in the ceiling of the building's fifth floor ruptured when the storm lifted the roof and caused it to move in a wave-like fashion.

“When (the roof) slammed back down it broke a sprinkler pipe," Bigler said. “That caused about 50 to 60 gallons a minute of water to start flowing through the building." All five stories were affected.
