PEX-A repiping refers to the process of replacing the existing pipes in a building with PEX-A, which stands for cross-linked polyethylene type A. This is a type of flexible plastic tubing that has become a popular choice for both residential and commercial plumbing systems. The “A” in PEX-A signifies that it has been cross-linked using the Engel method, which results in a more flexible and durable pipe. PEX-A pipes are resistant to scale and chlorine, do not corrode or develop pinhole leaks, and can withstand the rigors of freezing temperatures better than other types of plumbing pipes.

The process of PEX-A repiping involves removing old, often deteriorated pipes and installing new PEX-A pipes. This type of repiping is often chosen for its numerous benefits. These include cost-effectiveness, as PEX-A is generally cheaper than copper or other materials; ease of installation, as its flexibility means it can be threaded through walls and around corners without needing multiple fittings; and durability, as it’s resistant to many common causes of pipe failure. Moreover, PEX-A pipes can also result in better water pressure throughout your home, and they’re quieter, reducing the sound of running water or pipe expansion and contraction.
