A sewer camera is a specialized tool used to inspect underground pipes and sewer systems. It consists of a small, waterproof camera attached to a flexible cable that can be inserted into the pipes. This technology allows plumbers and maintenance workers to visually assess the condition of the pipes, identifying issues like blockages, cracks, or tree root intrusions. Using a sewer camera can save time and money by pinpointing problems without the need for extensive digging. The camera transmits real-time video footage, enabling professionals to make informed decisions about repairs or maintenance needed for the sewer system.
