Our main sewer line, from our house out to the city line, about a 70 foot distance, was clogged. The problem was that tree roots grew into the earthen pipe and ruptured the pipe in several places. We had a temporary fix but the problem would return in a few month. We needed to install a liner inside the broken earthen pipe. We got several estimates. However, The Drain Doctor Pro was the most promising. Greg came out the same day and explained the procedure. He ran a camera through the damaged sewer and took pictures the same day. He then used a rotor water jet cuter to clean out all the roots from the pipe and gave us a six month warranty. Greg and his Drain Doctor Pro crew returned several months later and in about 6 hours completed the entire job. They did a great job. I would highly recommend The Drain Doctor Pro in Bellflower CA and Greg and his crew. Ray K
