Which material shall not be used in the installation or repair of public or private water systems providing potable water for human consumption?

• A. Brass
• B. Plastic
• C. Lead
• D. Steel

Answer: (C)

The use of lead in the installation or repair of public or private water systems providing potable water for human consumption is prohibited due to the harmful health effects associated with lead exposure. Lead is a toxic metal that can leach into drinking water, particularly when water has high acidity or low mineral content. Consuming lead-contaminated water can lead to serious health issues, including developmental problems in children and various health complications in adults. In contrast, materials like brass, plastic, and steel are commonly accepted for use in plumbing systems. Brass is often used due to its corrosion resistance and durability, while plastics are favored for their lightweight and non-corrosive properties. Steel, appropriately treated, can also be used for various applications, including water systems, provided it meets safety and health regulations. The prohibition of lead as a plumbing material reflects a commitment to ensuring safe drinking water for all.
