I arrived to the customers home and they were experiencing a mainline blockage. I first ran a sewer camera to try and locate where their obstructed section of piping would fall and then tried running a cable machine to try and restore water flow temporarily. The camera was blurred by the line holding sewage, so I was unable to accurately identify what the obstruction was, but I was able to locate where the obstruction was in the piping. I then tried running a cable machine which was unsuccessful and kept binding up on what I believe to be tree roots. A sewer spot repair has been scheduled for today. work performed by TE certified will come with a lifetime warranty.
