Client called us out due to the fixtures in the basement backing up when a lot of water was used. Client has a city sewer cleanout out in the front yard by the road, and all these years have thought they were on city sewer. We pulled up the basement toilet and ran sewer camera. It took me out the back of the home, right under the concrete pad patio, where there are two 6” cleanouts just to the side of, that are full of poo and such. It turns out, client is actually on a septic system instead of sewer. After pulling toilet we saw the flange was not the correct flange for the pipe, so we replaced that flange with proper, then reset the toilet with new bolts and beauty caps, as well as new toilet supply line. After testing, we caulked around the base of the toilet. Client will need to call a septic company to further resolve this issue. Metro septic 678-873-7934
