The answer to 'sewer camera inspection not working' is that there are several common causes, including a faulty camera, issues with the camera cable, or problems with the sewer line itself. Symptoms may include the camera not powering on, the image being blurry or distorted, or the camera getting stuck in the sewer line.
In many cases, the issue can be resolved with some troubleshooting and minor repairs. However, if the problem persists or the sewer line is severely damaged, it's best to call in a professional plumber who can properly diagnose and fix the issue using specialized equipment and expertise.
