A Kitec repipe is a process that replaces outdated polybutylene (PB) pipes, commonly used from the 1970s to 1990s, with more durable modern pipes. Over time, PB pipes can become brittle, so replacing them with copper or PEX tubing helps ensure long-lasting, reliable plumbing. Copper resists corrosion, and PEX is flexible and freeze-resistant. Though Kitec repiping can be costly, it improves safety, energy efficiency, and provides peace of mind with a dependable water system.
