What was the primary practical advantage that led the Romans to utilize lead for their water pipe systems?

Answer

It was easily cast and malleable for joining sections

Roman engineers relied on lead for its high level of malleability and ease of casting. These physical properties were crucial for creating complex pipe networks, as they allowed workers to easily join and shape sections to navigate the internal layouts of cities and private homes. While the material posed significant health risks due to toxicity, its functional ease of installation made it the material of choice for Roman infrastructure.
