The answer to 'lifespan of sewer repair' is that a properly installed and maintained sewer line repair can last 50-100 years or more. Sewer line repairs, when done correctly, are designed to be a long-lasting solution that protects your home's plumbing system. The actual lifespan will depend on factors like the materials used, the quality of the installation, and how well the repair is maintained over time.
For example, trenchless sewer line repairs using pipe relining or pipe bursting techniques can provide a new, seamless pipe lining that is expected to last 50-100 years with minimal maintenance. Traditional sewer line replacements using new pipes and fittings may also have a similar lifespan if the work is done well. Proper care and routine inspections are key to maximizing the lifespan of any sewer repair.
