When a plumbing emergency happens, a plumber must be contacted immediately to help sort of the problem. A plumber who goes to a house that has a major water leak can turn off the water to help stop the home from being damaged further. This gives the homeowner a chance to begin cleaning up while the plumber gets to work handling the leak and getting the water turned back on. Any time when the home is being flooded, it is best for an emergency plumber to be called immediately.
The word "plumber" dates from the Roman Empire. The Latin for lead is plumbum. Roman roofs used lead in conduits and drain pipes and some were also covered with lead, lead was also used for piping and for making baths. In medieval 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.
