The answer to 'types of repiping' is that there are several common types of repiping that a plumber may recommend for a home. Repiping involves replacing all or part of a home's existing plumbing system, usually to address issues like leaks, low water pressure, or outdated materials.
Some of the most common types of repiping include copper repiping, PEX repiping, and repiping with CPVC pipes. Copper repiping uses rigid copper pipes, while PEX uses flexible cross-linked polyethylene tubing. CPVC (chlorinated polyvinyl chloride) is another durable plastic option. The best type for your home will depend on factors like the existing plumbing, your budget, and the accessibility of the pipes.
