Plumbers need to know math, applied physics, chemistry, and drafting. They must be able to read blueprints, follow directions, and use the tools of the plumbing trade safely. They must be able to make decisions and work independently. Plumbers who work directly with customers need good communication skills.

After graduating from a career and technical center, I enrolled in a 4-year apprenticeship program that included on-the-job training and 144 hours of classroom instruction each year. My union apprenticeship was sponsored by the United Association of Journeymen and Apprentices of the Plumbing and Pipefitting Industry of the United States and Canada. Other non-union apprenticeships are sponsored by associations like the Home Builders Institute and the National Association of Home Builders.
