Review: Hired plumber to remove and repair a cracked cast iron sewer line.plumber removed some of the line but left 2 feet of cracked line so when the toilet is flushed all sewage come out and drops to basement. When I showed the plumber the problem he stated he was going to charge for repair. I have already paid for this if this was done correct the first time I would not had to break down the wall to show he the problem. I would like the repair done for which I pay for.Desired Settlement: I need the pipe repaired
