The answer to 'when to replace sewer camera inspection' is that you should typically replace your sewer camera inspection equipment every 3-5 years, depending on how frequently you use it and the conditions it's exposed to. Sewer cameras are durable tools, but the internal components and image quality can degrade over time, especially if the camera is frequently submerged in water or exposed to corrosive sewer gases.
Regular maintenance and calibration can extend the life of your sewer camera, but at a certain point, the costs of repairs and diminished performance make it more practical to upgrade to a newer model. Most plumbing professionals recommend replacing your sewer camera every 3-5 years to ensure you have reliable, high-quality footage for inspecting pipes and diagnosing issues.
