John and Jerry Thanks for the info. I'm working on it from your info.
Jerry to answer your question.
Highrise building, clamp on cap blew off of a 6" water pipe on the 29th floor;
Result- flooded portions of 4-6 units per floor and hallways, 29 floors down to basement.
Tenants flipping out and displaced; Tons of drywall removed, Environmental guy onsite everyday, etc. Removal and repairs ongoing.
I looked at the problem pipe and a new pipe, clear and evident difference in groove depth and curvature.
I do ongoing work for this client. Figured I would do some research for potential additional work and brownie points. I'm sure all sides will have lots of lawyers involved soon.
