A high-level look at the plumbing profession

Plumbing contractors encompass a wide range of professionals and generally include anyone who installs or repairs pipes that carry liquids or gases. Plumbing contractors work in both residential and commercial settings and are often on call at all hours for situations such as leaks or pipe bursts that require immediate attention to prevent serious, long-term damage.

Typical residential tasks for plumbing contractors can include fixing leaking pipes, installing sinks and toilets, and repairing or replacing water heaters and water conditioning equipment. On the commercial side, plumbing tasks can include residential-type plumbing jobs (e.g., installing bathroom fixtures), mechanical services, sprinkler system installations and repairs, steamfitting and pipe services, and lawn sprinkler system maintenance.

In most instances, plumbing contractors will complete an apprenticeship or a technical school program in order to gain experience. In terms of certification, most states and cities require plumbers to be licensed.1

Plumbing businesses can range in size and include entrepreneurial individuals working for themselves, small independent businesses and large national operations. There are also plumbing franchises that are independently owned with set territories.

However, it should be noted that plumbing contractors are a part of larger construction trends. This means that an economic downturn affecting the construction industry would have a significant impact on plumbers.
