Florida Home Inspector Practice Test 2025 – Comprehensive Exam Prep

The most common supply piping material used in modern home construction is copper. Copper has long been favored in the plumbing industry due to its excellent durability, resistance to corrosion, and strong performance in both hot and cold water systems. Its versatility allows it to be used in a wide range of plumbing applications, including interior and exterior installations.

One of the key advantages of copper is its ability to withstand high temperatures and pressures. This makes it suitable for water supply lines, as well as for systems that may carry hot water, such as heating systems. Additionally, copper piping has antimicrobial properties, which help prevent the growth of harmful bacteria within the plumbing system.

While other materials like PVC and PEX are gaining popularity, especially for certain applications due to their lightweight and ease of installation, copper remains the preferred choice in many residential settings due to its longevity and reliability. Understanding the various materials used in supply piping is essential for home inspectors, as they need to be aware of the materials that are current in construction practices and their suitability for different plumbing needs.
