The answer to 'repiping clogged' is that repiping is typically required when a home's plumbing system has become severely clogged or damaged over time. Common causes include mineral buildup, tree root intrusion, and aging pipes. Symptoms may include slow draining sinks, frequent clogs, leaks, or low water pressure.
Repiping the entire plumbing system is often the best solution, as it involves replacing the old pipes with new, corrosion-resistant materials like copper, PEX, or PVC. This can be a major project, so it's generally best to call in a professional plumber unless you have extensive plumbing experience. They can assess the extent of the issue and recommend the most appropriate repiping solution for your home.
