Which plumbing material is known for its flexibility and ease of installation?

The material known for its flexibility and ease of installation is PEX (cross-linked polyethylene). PEX is designed to be highly flexible, allowing it to be bent easily around corners without the need for fittings, which reduces the potential for leaks and makes installation faster and less labor-intensive. This flexibility also helps it to expand and contract with temperature changes without breaking, making it ideal for various plumbing applications.

Moreover, PEX does not require joint fittings for long runs, which not only saves time during installation but also minimizes the risk of leaks, making it a popular choice among plumbers. Its lightweight nature also contributes to its ease of handling on job sites.

While other materials, such as CPVC and PVC, are commonly used in plumbing systems, they do not offer the same level of flexibility. Cast iron, on the other hand, is much heavier and more rigid, making it difficult to manipulate during installation.
