The answer to 'my sewer camera inspection smells bad' is that a foul odor coming from a sewer camera inspection is often caused by a blockage or buildup in the sewer line. This can lead to the release of noxious gases that create an unpleasant smell. Common causes include debris, grease buildup, tree roots, or a broken pipe.
The symptoms may include a strong sewage-like smell, slow draining sinks or toilets, and potentially water backing up in your home. While this can be a DIY project for some homeowners, it's generally best to call a professional plumber to properly diagnose and resolve the issue, as sewer line problems can be complex and dangerous to address on your own.
