Stopped Up Kitchen Sink

A customer called Superior Plumbing & Drain. His kitchen sink was backing up. The pipe was only 2", therefore too small to run a camera. Our Master Plumber, Robert, ran a snake through the pipe but could not clear it. The house was built in 1975 & we knew the pipes were cast iron. Robert had to jackhammer the floor in the garage. He found 8 feet of rotten pipe. We were able to replace the cast iron with PVC pipe and repair the concrete floor.
