Plumbing is a traditional profession that has had to evolve as new modern water, wastewater and gas systems have been invented. Plumbers install and fix water, drainage and gas systems in homes and commercial buildings and other areas such as wastewater treatment facilities.
Plumbers must be able to read and interpret blueprints and schematics and follow these plans meticulously paying close attention to detail.
Plumbers need to work with various materials for installations and repairs and although no formal education is needed, a four or five year apprenticeship is needed. Although no state license is needed to practice, a local license is usually required.
Plumbing is one of those professions that see little unemployment. Even in poor economic times, repairs and maintenance of systems is needed.
