The answer to 'when to replace sewer camera inspection' is that sewer camera inspection equipment should typically be replaced every 5-10 years, depending on usage and wear and tear. Sewer cameras are an essential tool for plumbers to inspect and diagnose issues in underground sewer and drain lines, but the internal components and image quality can degrade over time.
Regular maintenance and proper care can extend the lifespan of sewer cameras, but they will eventually need to be replaced as the technology evolves and the equipment becomes outdated. Factors like the number of inspections performed, exposure to harsh environments, and proper storage and handling can all impact the longevity of sewer cameras. It's a good idea to consult with a professional plumber to evaluate your existing equipment and determine when replacement may be necessary.
