The answer to 'repiping not working' is that there could be several common causes, such as improper installation, incorrect pipe sizing, or issues with the new plumbing materials. Symptoms may include leaks, low water pressure, or discolored water. Solutions can range from adjusting connections to completely replacing the new plumbing system.
If you're experiencing issues with a repiping project, it's generally best to call a professional plumber to diagnose and fix the problem. Repiping a home requires specialized skills and tools, and attempting DIY repairs could lead to further damage or safety issues. A qualified plumber can inspect the system, identify the root cause, and provide the appropriate solution to get your plumbing working properly again.
