The answer to 'how to unclog sewer camera inspection' is to first check the sewer line for a blockage using a sewer camera. If a blockage is detected, you can try to clear it using a sewer snake or auger. Start by inserting the sewer snake into the line and rotating it clockwise to break up the clog. If the blockage is severe, you may need to use a high-pressure water jetter to flush out the line.
It's important to take safety precautions when working with sewer lines, such as wearing gloves and eye protection. If the blockage is not clearing or you're unsure of the cause, it's best to call a professional plumber to inspect and clear the line.
