We had a bathroom remodel down in 2012. Zellner replaced the pipes going from our house to the city sewer lines. In October of this year we noticed the pipes were not flowing as well and the water sometimes backed up in the house. We called rotorooter who came out with their camera and showed were the pipe had a downward bow in it and that was clogging up. I caller John and he agreed to come out take a look at it and if his work was the problem they would repair it at no cost, even though the pipe has been in the ground for over a year. His workers came out, dug up the old pipe, replaced it with new and covered up the line. As far as I am concerned John Zellner did exactly as he promised. He stood by his work and I appreciate that.
