The answer to 'how to unclog sewer camera inspection' is to use a sewer snake or plumbing auger to clear the clog. First, locate the sewer cleanout, which is a pipe that provides access to the main sewer line. Remove the cap and insert the end of the sewer snake into the cleanout. Crank the handle to feed the snake into the pipe and break up the clog. If the clog is deeper in the line, you may need to use a sewer camera to locate the exact position of the blockage before using the snake.
If the clog is severe or you are unable to clear it with a snake, it's best to call a professional plumber. They have specialized equipment and expertise to properly diagnose and clear sewer line clogs without causing further damage.
