The answer to 'pipe replacement frequency' is that there is no single, universal rule for how often pipes should be replaced. The lifespan of pipes can vary widely depending on factors like the material, installation quality, water quality, and usage patterns. On average, most plumbing pipes last 50-100 years, but certain types like galvanized steel may only last 20-50 years, while copper and PVC can last 70-100 years with proper maintenance.
It's important to regularly inspect pipes for signs of wear, corrosion, or leaks, and replace them before major problems occur. Homeowners should also be aware of the pipe materials in their home and monitor them accordingly. Calling a professional plumber for a whole-home plumbing inspection every 5-10 years is a good way to proactively identify and address any pipe issues.
