I started having sewer line clogs randomly which finally led to a total block. I had another company come out at first to clear the blockage, but this only lasted two weeks. Then I called Austin Plumbing come out and met Jim. We found that on the original install 70 years ago the sewage lines were installed without gravel under them and the joints sank in the clay forming "bellies". It was a large job to saw cut my floor out and replace everything. In the end everything was great and I haven't had a problem since. Jim and the gang were great guys with positive attitudes and the project was done at a reasonable price.
