In terms of potability, what is a critical factor to consider when selecting pipes for water supply?

When selecting pipes for water supply, material safety for drinking water is paramount. It is essential to use materials that do not leach harmful substances into the water, ensuring the safety and health of the consumers. This focus on potability means using materials that are approved and certified for drinking water use by relevant health and safety standards.

While factors like cost of materials, physical durability, and ease of installation are important in other contexts, they do not prioritize the health risks associated with water consumption. For instance, a cheaper material may not be safe, and a highly durable option might still be toxic to human health. Therefore, ensuring that the pipes used in water supply systems are safe for drinking is critical to maintaining public health and adhering to regulations regarding potable water.
