Sewer camera inspections are a quick and easy way to determine the health of your plumbing systems and detect issues early before they become expensive repairs. Sewer camera inspections involve a small waterproof video camera mounted on the end of a flexible cable. This camera snake is inserted into the sewage system and pushed through the pipeline in order to do a visual inspection. These cameras can be used in underground pipes as well as pipes encased in concrete, located behind walls, or beneath your home’s foundation.
