What is the origin of the modern term "plumber"?

The modern term "plumber" has its roots in the Latin word "plumbum," which means lead. Historically, many plumbing systems were made with lead pipes, and individuals who worked with these materials were known as plumbers. This connection to lead is a significant aspect of the term's origin, emphasizing the materials used in early plumbing. Over time, while the materials and techniques have evolved, the name has remained largely unchanged, reflecting the profession's historical ties to working with lead and plumbing systems in general.
