As with other skilled trades, most states require training and professional licensing before you can legally install, repair, and maintain plumbing systems. While the plumbing trade has been around since the 1800s, today’s plumbers need a wide range of skills to work in residential and commercial settings. Depending on the nature of the job, plumbers often work alongside electricians, HVAC techs, general contractors and other professionals in the construction industry.

Candidates typically need to be 18 years old and have a high school diploma or GED, photo ID, and a valid driver’s license to be eligible.

Apprentice plumbers in New Mexico must complete at least four years of on-the-job training as well as 144 hours of related classroom instruction via a plumber’s union, trade school, or community college.
