Plumbing involves the installation of service piping systems for residential and commercial structures. This profession accounts for part of the largest and highest paid occupation in the construction industry.
After training and experience, most states require a plumber to become licensed. Job prospects for those entering the plumbing profession are expected to be in high demand due to increases in construction and building renovation. Plumbers often work for companies as an in-house plumber, contractors or, after some experience, can work independently.
