A plumber is a tradesperson who specialises in installing and maintaining systems used for potable (drinking) water, sewage and drainage in plumbing systems. The term dates from ancient times and is related to the Latin word for lead, "plumbum".
The word "plumber" dates from the Roman Empire. The Latin for lead is plumbum. Roman roofs used lead in conduits and drain pipes and a few were additionally covered with lead, lead was additionally used for piping and for making baths. In mediaeval times anyone who worked with lead was referred to as a plumber as can be seen from an extract of workmen fixing a roof in Westminster Palace and were referred to as plumbers "To Gilbert de Westminster, plumber, working about the roof of the pantry of the little hall, covering it with lead, and about various defects in the roof of the little hall". Thus a person with expertise in working with lead was first known as a Plumbarius which was later shortened to plumber.
Years of training and/or experience are needed to become a skilled plumber; a few jurisdictions additionally require that plumbers be licensed.

Each state and locality might have its own licencing and taxing schemes for plumbers. There is no federal law establishing licences for plumbers.
In Canada, licencing requirements differ by province, however the provinces have pooled resources to develop an Interprovincial Program Guide that developed and maintains apprenticeship training standards across all provinces. The result is what's known as the Interprovincial Standards Red Seal Program.
Plumbers in the United Kingdom are required to pass Level 2 and Level 3 vocational requirements of the City and Guilds of London Institute.
Plumbers in Australia have licencing requirements that differ from state to state but it is generally accepted a 4 year apprenticeship with a further minimum experience of 2 years (6 years total) and a further curricular requirement as a benchmark for licencing. Licensed plumbers are additionally expected to maintain minimum relevant training requirements to maintain their plumbing license.

Their job was to plug intelligence "leaks" in the U.S. Government relating to the Vietnam War (i.e. the Pentagon Papers); hence the term "plumbers".
