Job Opportunities

Needless to say, employers love not only job candidates with experience, but those with professional credentials as well. Holding a certification as a journeyman or master plumber will set you apart from your competitors in the job market, and qualify you for jobs in highly-specialized areas.

Holding a certification is also usually considered to be mandatory for anyone who plans to become an independent contractor. If your goal is to open your own business, you’ll definitely want to secure the certification appropriate for your level of experience as well as specialized certificates for your area of expertise.


It’s no secret that experts are paid more than general practitioners in most industries, and plumbing is no exception. Quotes for the installation and maintenance of specialized systems are always considerably higher than those for standard piping and, as a result, those who specialize in working on them can usually expect better pay.

When you consider that a several month investment in a certification course can result in thousands of dollars per year in additional earnings, it should be an easy decision to pursue this additional training.


Ask any long-time plumbing professional and he or she will most-likely tell you that advancement in the industry is often closely-tied to an individual’s level of training.

It stands to reason that anyone who advances into a management position will need to be familiar with the requirements for many different kinds of jobs. This familiarity often comes from completing certification training in a variety of areas.


In any construction-related field, adhering to safety standards is critical. This is also the case with plumbing where exposure to heat, chemicals and other hazards is a daily part of the job.

All plumbing certification programs dedicate time to ensuring that students are up-to-date with industry safety standards and are able to pass local state examinations on the topic.
