Master Plumber

Something as simple as swapping out a pipe fitting (under a dollar for the part) to fix leak can easily end up saving you thousands in water damage and avoid a major disruption in your household for weeks. This is why hiring a licensed and insured master plumber is a no-brainer. The important thing to remember is that not all plumbers have the experience and expertise it takes to perform all types of work. There are two categories when it comes to plumbers – those that can handle basic repairs and master plumbers who have the training and experience necessary to handle any plumbing project successfully.

What is a Master Plumber?

A master plumber is a professional that has completed comprehensive training and assessment and has years of experience. The outcome of the in-depth training and successful testing is certification and licensing by their specific state. This is a designation that plumbers aspire to but not all achieve.

How Does a Master Plumber Differ from a Licensed Plumber?

Master Plumber

A master plumber in Arizona is a highly skilled expert, differing from a regular plumber primarily because of their level of experience and the fact that they’ve earned the master plumber designation and have been licensed and certified by the state as such. Master plumbers have a higher level of skill than regular plumbers, and their expertise includes repair and maintenance of both outdoor and indoor plumbing. They also have extensive knowledge of codes and regulations at the federal and state level. Master plumbers, similar to other professionals, sometimes choose to specialize in a specific area of plumbing. Because of their expert designation, they are often hired to perform the design and installation of sophisticated plumbing systems on construction sites.


Becoming a plumber typically includes three key steps. Aspiring plumbers usually start as apprentices, with the next step being to progress to journeymen after spending state-mandated years of on the job work experience. To move on to the third step, becoming a master plumber (the highest level), requires experience as a journeyman plumber. A plumber with a journeyman’s license will need to work under a master plumber in Arizona for a minimum of four years before they are able to take the test to earn a master plumber standing. The plumber will need to prove their ability to work on major, comprehensive projects and will also be tested on their knowledge of federal and state codes of practice.

What’s Required for Arizona?

To become licensed as a plumber in Arizona four years of documented experience in the plumbing trade is required. To get the experience, you can work under the guidance and supervision of a licensed plumber that you find on your own or through an apprenticeship program that’s Arizona approved. Next, you’ll need to take exams typically taken online. You’ll need to sit for commercial or residential trade exams and a business management exam.

Once the exams have been passed the license can be applied for. Along with the license application from the Arizona Registrar of Contractors site, you’ll need to include verification that you’ve completed four years of on the job experience and passed the trade exam. You’ll also need to have a license bond that you include with your application. This can be in the form of a cash bond, surety bond, or certificate of deposit. Once you have the full application package together, it needs to be sent to the Arizona Registrar of Contractors.
