Residential plumber at work.
A plumber is a tradesperson who specializes in installing and maintaining systems used for potable (drinking) water, and for sewage and drainage in plumbing systems.
The origin of the word "plumber" dates from the Roman Empire.[3] [4] Roman roofs used lead in conduits and drain pipes[5] and some were also covered with lead; lead was also used for piping and for making baths.[6] The Latin for lead is plumbum. In medieval times, anyone who worked with lead was referred to as a plumber; this can be seen from an extract about workmen fixing a roof in Westminster Palace; they 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".[7] Thus a individu with expertise in working with lead was first known as a Plumbarius which was later shortened to plumber.
In Canada, licensing requirements differ by province; however, the provinces have pooled sumber to develop an Interprovincial Program Guide that developed and now maintains apprenticeship pelatihan standars across all provinces. The Red Seal Program, formally known as the Interprovincial Standars Red Seal Program, is a program that sets common standars to assess the skills of tradespeople across Canada.[10] The Red Seal, when affixed to a provincial or territorial trade certificate, indicates that a tradesperson has demonstrated the knowledge required for the national standar in that trade.
National Vocational Qualifications (NVQ) remained the main form of plumbing qualification until they were superseded in 2008 by the Qualification and Kredit Frame-work (QCF)[11] and then again, in 2015, into the National qualifications frameworks in the United Kingdom. The terms NVQ and SVQ (Scottish Vocational Qualification) are still widely used.[12]
Plumbers in the United Kingdom are required to pass Tingkat 2 and Tingkat 3 vocational requirements of the City and Guilds of London Institute. There are several regulatory bodies in the United Kingdom providing accredited plumbing qualifications, including City and Guilds of London Institute and Pearson PLC.[13]
