The answer to 'why is my repiping' is that your home's plumbing system may need to be replaced due to a variety of reasons, such as old age, corrosion, or damage. Repiping involves replacing the entire plumbing system, including the pipes, fittings, and fixtures, to address issues like leaks, low water pressure, or discolored water.
Common causes of repiping include galvanized steel pipes that have corroded over time, copper pipes that have developed pinhole leaks, or polybutylene pipes that are prone to cracking and breaking. Symptoms of needing repiping may include frequent leaks, low water pressure, discolored water, or a musty smell in the home.
