Most drain cameras can only go 330 to 350 feet. Drones can go much further, traveling several hundred feet under your property. Your plumber will determine the best drain to use for the scope and run the device until they discover the source of the problem or reach the end of the private line connecting your home to the municipal sewer.
Without proper training, you may not be able to identify what you see during the sewer video inspection, even if the video quality is high. Ask your plumber to walk you through the inspection and show you what they find. Modern equipment often contains bright lights and self-leveling technology to get an upright view of the pipes.
Inspecting a home’s sewer lines with a camera is a quick job, usually taking a professional sewer inspector just 30 minutes to an hour to complete. It might take slightly longer if your sewer lines are particularly long or if your pro has issues accessing them.
