Report number
Location
OK, KAY
Narrative
The cause of the incident was not a construction defect as originally theorized. The post-incident laboratory examination of the pipe and weld took place may 14-15, 2019. The preliminary report from the expert indicated that the bond at the pipe joint did not have any evidence of de-bonding and had comparable tensile strength to exemplar fusion bond joints. The leak that occurred at the pipe joint appears to be from a stress-induced crack near the pipe joint.
