Plumber
Plumbers install, repair, and maintain water supply lines, drainage systems, gas piping, and fixtures in residential and commercial buildings. Like electricians, most states use a tiered license system (apprentice through master) requiring years of supervised work. Plumbers also need EPA Section 608 certification for handling refrigerants in some crossover work.

The Landscape
Looking at the national picture for plumbers, clear regional patterns emerge regarding earning potential and regulatory landscapes. The Northeast and upper Midwest, including states like Illinois at $96,200, Oregon at $93,110, and Minnesota at $83,280, consistently offer top-tier median salaries. This often reflects higher costs of living and robust demand in dense urban centers, creating a competitive market for skilled trades.
However, not all high-paying states follow standard licensing models. New York, for instance, offers a median salary of $78,460 without a statewide license, meaning local city and county regulations are paramount and can be quite stringent, especially in metropolitan areas. In contrast, states like Pennsylvania, Nebraska, Kansas, Missouri, and Wyoming also lack statewide licensing, but their plumbers earn closer to the national median or below, suggesting local oversight might be less rigorous or market demand is lower.
The journey to licensure itself varies significantly. While many states demand around 8,000 hours of experience, a few like Hawaii and New Jersey extend this to 10,000 hours, prolonging the apprenticeship path. Conversely, states such as Delaware, Kentucky, and Maine require as few as 4,000 hours, offering a quicker entry point into the profession, though often with lower initial earning potential.
