The answer to 'lifespan of pipe' is that the typical lifespan of plumbing pipes can vary greatly, but most commonly they last between 50-100 years. The exact lifespan depends on the type of pipe material, the quality of installation, and the local water conditions. Copper pipes tend to last the longest, often 70-100 years, while galvanized steel pipes may only last 40-50 years. Plastic pipes like PVC can last 50-80 years with proper installation.
It's important to regularly inspect your home's plumbing system and address any issues promptly to maximize the lifespan of your pipes. Calling a professional plumber for an inspection every 5-10 years is recommended to identify any potential problems early on.
