What is a Master Plumber?

A master plumber is a licensed professional plumber who has passed the rigorous state testing and certification process for plumbers. To get this designation, a plumber has not only passed the tests but accumulated years of practical experience in the field of plumbing.

What is a master plumber?

A master plumber possesses a variety of skills necessary to install and maintain indoor and outdoor water service. These skills include advanced maintenance and repair of indoor and outdoor plumbing systems and sanitary knowledge and storm sewer service. Master plumbers possess extensive knowledge of state and federal plumbing codes.

Master plumbers may contain specialties such as steam fitting (pipe installation for the transport of high pressure gases). Master plumbers also supervise plumbing works on construction sites. Their experience and knowledge allows them to elaborate more complex plans of buildings of several levels and sanitary systems.


A first step toward becoming a master plumber is to earn an associate’s degree or complete a professional program at a technical school. Classes include math, industrial chemistry and mechanical drawing courses as well as basic plumbing concepts. Skills include pipeline identification and flat reading. With that knowledge, you can teach, help expert plumbers and learn from experience. While an advanced degree is preferred, only a high school diploma or GED is required to apply for formal learning through organizations such as the plumbing industry council.


There are educational programs for four to five years and are typically run by local unions or their affiliated companies, according to the Outlook Handbook’s Labor Statistics Office 2008-09. Plumbing trainees are trained in paid work as well as classroom instruction.

After this apprenticeship, a plumber may apply for the trader’s license or choose to work longer years under direct supervision and obtain a day laborer’s license. Before a plumber can take the Master Plumber examination, most states require four to five years of experience at the official level. This amount varies by state. Once an officer’s license is obtained, a further year of supervision under a master plumber is often necessary to refine the skills required by master plumbers. The plumber should be licensed as well.

Plumber Master Certification

Certification of master plumber varies by state. The tests generally evaluate a plumber’s ability to install, repair and maintain plumbing systems as well as manage the main plumbing work. The certification process also tests knowledge of a state plumber and federal plumbing.

Career Options

Due to their advanced skills and oversight functions, master plumbers generally earn more than journeyman plumbers. According to Salary.com, the salary range of a master plumber stands at $65,300. The top range for a passing plumber will be around $ 50,000.

Employment prospects for plumbers will remain strong as the need for new construction and renovation grows, according to the Bureau of Labor Statistics. Demand for highly skilled and qualified master plumbers is likely to outstrip the supply of workers in this field, the table predicts. Even when building activity decreases, the need for maintenance, replacement and new facilities will keep the demand for prime plumbers high, especially on a contract basis.
