Indoor plumbing involves the methods used to move water for washing, cooking, and sanitation.
Plumbers install and repair systems to manage water, sewage, and drainage, while pipefitters and steamfitters are specialized tradesmen who install and maintain certain types of pipes for liquids and gases.
Plumbing originated during ancient civilizations, such as Greek, Roman, Persian, Indian, and Chinese cities, as they developed public baths and needed to provide water and wastewater removal for larger numbers of people.
In the United States, Boston pioneered the first water system in the mid-1600s. The first valve-type flush toilet was invented by J.F. Brondel in 1738, while Alexander Cumming patented the flush toilet in 1775.
Plumbers, pipefitters, and steamfitters install and repair piping fixtures and systems to manage water, sewage, and drainage.
Plumbers install and repair water, gas, and other piping systems in homes, businesses, and factories. They install plumbing fixtures, such as bathtubs, showers, and toilets, as well as appliances, such as dishwashers and water heaters. They clean drains, remove obstructions, and repair or replace broken pipes, fixtures, and septic systems.
Pipefitters and steamfitters install and maintain pipes that may carry chemicals, acids, and gases. These pipes are mostly in manufacturing, commercial, and industrial settings. Steamfitters specialize in systems designed to handle the flow of liquids or gases at high pressure.
Plumbers, pipefitters, and steamfitters work in homes, commercial buildings, factories, and other places where there are pipes and related systems. As plumbers are often called out on emergencies, evening and weekend work is common.
Typically, a high school diploma or equivalent is required to become a plumber, pipefitter, or steamfitter. Vocational or technical schools offer essential training and qualifications for individuals interested in becoming plumbers. These courses include both theory and hands-on training to equip students with the skills and knowledge needed to work effectively in the trade. They also offer welding courses that may be required for pipefitter and steamfitter apprenticeship programs.
Most plumbers, pipefitters, and steamfitters learn their trade through a 4-5-year apprenticeship. Apprentices receive paid on-the-job training and technical instruction in safety, local plumbing codes and regulations, and blueprint reading. Apprenticeship programs are sponsored by unions, trade associations, and businesses.
While regulatory requirements differ from one jurisdiction to another, plumbers, pipefitters, and steamfitters typically complete an apprenticeship program and pass a required licensing examination to become journey-level workers, who are qualified to perform tasks independently. Plumbers with several years of experience may sit for another exam to earn master status.
Most states and some localities require plumbers to be licensed. Although requirements vary, workers are often expected to have 2 to 5 years of experience and pass an exam before working independently. Plumbers may also obtain optional certification, such as in plumbing design, to broaden career opportunities. Some states require plumbers to be licensed, and may require a special license to work on gas lines. Licensing typically requires an exam, work experience, or both.
