The answer to 'lifespan of repiping' is that a well-executed repiping project can last 50-80 years or more. Repiping involves replacing all the old, outdated plumbing pipes in a home with new, modern materials like copper, PEX, or CPVC. This extensive plumbing system overhaul is a major investment, but it can significantly extend the life of a home's plumbing infrastructure.
The lifespan of repiped plumbing depends on factors like the quality of the materials used, the workmanship of the installation, and the home's water quality. With proper maintenance, a repiped system can function reliably for decades. However, some signs that repiping may be needed include frequent leaks, low water pressure, discolored water, and outdated galvanized steel or polybutylene pipes.
