I would rate -0- if possible. A-OK replaced our sewer line from house to city main in March, 2018, with root-proof pvc and one-yr warranty. In September, 2018 the sewer started backing up into the house again, and plumbers ran snake down line, then said I forgot about the clean-out. They started digging around the clean-out and discovered roots in it which resulted in a deep pit and mudpile. At the same time we discovered our hot water tank was leaking, so asked for a cost on it. Since it was almost weekend, we agreed to the installation. They stopped working on the sewer and took off to get the hot water heater. During installation, they broke the garage floor drain cover but said the owner was getting one for us, also did not install the drain line from tank to floor.They went back to the sewer line, dumped some root killer in the line and said they would leave the pit for possible backups until they could get back and finish. (It was Tulsa State Fair weekend and they were anxious to leave.) We never saw or heard from them again. We have been calling their number, 918 810-0397, but it goes to voice mail and no one calls us back. We now have a raw sewage pit in the backyard and incomplete hot water heater installation, and A-OK Plumbing has our money for two jobs. Don't even think about using this company if you want a completed job with a good warranty. What do we do now?
