The answer to 'sewer camera inspection won't flush' is that a clogged or blocked sewer line is likely the cause. This can happen if the sewer line has a buildup of debris, tree roots, or other blockages that prevent proper flushing and drainage. Symptoms may include slow draining sinks, gurgling sounds, or sewage backups.
To address this issue, you'll first want to try a basic plunger or drain snake to see if you can clear the blockage. However, if the problem persists or you're unable to locate the source, it's best to call in a professional plumber to perform a sewer camera inspection. They can use specialized equipment to identify the exact location and nature of the blockage, then recommend the appropriate solution, whether that's hydro-jetting, pipe relining, or even sewer line replacement.
