Becoming a Plumber in Illinois

Becoming a Plumber in Illinois

There are numerous reasons to become a plumber. These include:

  • Job security
  • Good pay
  • The ability to be your own boss
  • You help people
  • Job variety
  • Stimulating work
  • Low cost of entry
  • Social interaction
  • Respect from your customers
  • No more plumbing bills

So how does one become a plumber in Illinois? Here is what is required:

  • Age 16 or older
  • Must be a U.S. citizen or in the process of becoming one
  • Completed at least two years of high school or equivalent
  • Completed an approved course instruction through a college, university or trade school
  • Been a licensed apprentice plumber for a minimum of four years working under a licensed plumber. Apprentice plumbers perform many of the same tasks as licensed plumbers, including:
    o Installing new plumbing fixtures
    o Unclogging drains and sewers
    o Repairing, assembling and cutting pipes
    o Cleaning water supply and disposal systems
    o Preparing and cleaning job sites
    o Responding to customer inquiries

In Illinois you must complete an application to be an apprentice plumber. The application costs $100.
Upon completion of these requirements, you can apply to become a licensed plumber in Illinois. The application fee is $175 for apprentice plumbers in Illinois, and $225 for plumbers licensed in Chicago or outside the state of Illinois.

A few things to keep in mind:

  • Once you start your apprenticeship, you have seven years to obtain the necessary on the job training hours and pass the license exam.
  • You cannot take the license exam until you have completed your apprenticeship, which usually takes five years
  • The license exam is comprised of a written portion where you are tested on your knowledge of the plumbing code and a practical portion where you have to fabricate several different assemblies of water and waste piping that are tested for dimensional correctness and ability to hold pressure.

On average, 72% of the people taking the plumbing exam fail the exam. If you cannot pass the exam within the seven-year time frame (after completing your five-year apprenticeship), you cannot be a plumber without starting over from the beginning.
