Most states require that a plumber have some kind of license, although there is no standard licensing requirement the way there is for, say, the medical profession. While requirements vary, most professional plumbers have fulfilled certain common essentials by the time they are seeking a license.
Those essentials include a minimum of two yeas of experience in the field, although five is better. They must be able to pass a plumbing exam that measures their aptitude for the trade. And they should have a good working knowledge of the plumbing codes in the municipality they intend to work in.
Professionally, there are two main categories of plumber: the Journeyman plumber, and the Master plumber. A Journeyman is plumber who has completed an apprenticeship or training program and has the skills to work for a Master plumber. A Master plumber is one has taken and passed an examination given by the state or city in which he or she is working, and has received a Master plumber license. Such a plumber is authorized to be an employer or contractor, and can teach and employ journeyman plumbers.
The principle services provided by plumbers include the installation or repair of water, waste disposal, drainage, and gas systems in buildings. They also install appliances like hot water heaters, dishwashers, and plumbing fixtures, including bath tubs, sinks, and toilets.
