Lead shall not be used in the installation or repair of potable systems.

• A. Lead
• B. Copper
• C. Plastic
• D. Iron

Answer: (A)

Lead must not be used in potable water systems. This is because lead can dissolve into drinking water, and even tiny amounts pose serious health risks, especially to children and pregnant people. Over time, regulatory standards have established that materials contacting potable water must be lead-free, leading to widespread use of copper, various plastics, or iron that meet those lead-free requirements. So the statement is correct because it identifies the material that is prohibited for drinking-water installations. Copper, plastic, and iron are acceptable alternatives when installed according to current codes and with components certified as lead-free.
