The answer to 'sewer camera inspection overflowing' is that a sewer camera inspection can sometimes lead to a sewer line overflow due to blockages or damage discovered during the inspection process. When a sewer camera inspection is performed, the plumber may encounter a clog, break, or other issue in the sewer line that causes a backup and overflow.
In some cases, the act of inserting the sewer camera into the line can dislodge debris or damage the pipe, leading to an immediate overflow. This is because the inspection is intended to identify problems, but the process itself can sometimes exacerbate the issue. Homeowners should be prepared for the possibility of an overflow when scheduling a sewer camera inspection, and have a plan in place to address any problems that are found.
