IL, KANE
Narrative
While tapping a fitting on an extra thick 3-inch service line to abandon the service line, the hole saw created a hairline crack on the side of the pipe, generating a small leak. In order to stop the leak, the 12-inch header had to be stopped. There are no repair costs associated with this incident since the reason for the work being performed was to abandon the 3" service line. The hairline crack width had to be rounded up to 0.1 since the database does not accept values less than one decimal point.
