WSSC Exams – Master Plumbing, Master Gas Fitting, Journeyman Plumbing and Journeyman Gasfitter
The exams are administered by PSI. All of a candidate’s requirements and qualifications can be found in the PSI Application.
At the completion of the test, the PSI center will issue you an exam score report. If you have a passing score, instructions on how to obtain a WSSC license will be printed on the report and presented below.
WSSC reciprocates all plumbing and gasfitting license types with the State of Maryland and the Commonwealth of Virginia, although an apprentice license need not be reciprocated.
To apply, see Application procedures below.
A license (in good standing) from any other State and the District of Columbia qualifies an applicant for WSSC examination, see WSSC Code Section 115 for specific requirements.
Applicants garnering no trade experience may apply for an apprentice license for one of the following types: plumbing, gasfitting, or the combination of plumbing & gasfitting.
An Apprentice license shall be issued without an expiration date and remains in good standing until he/she progresses up to the Journeyman level or until otherwise deactivated.
An Apprentice license authorizes an individual to only assist in providing plumbing/gasfitting services; meaning an apprentice shall not work alone on a job site without direct supervision by an appropriate Journeyman or Master level licensee.
Applicants will qualify for a sewer and drain cleaning license after working 3750 hours (two years), under the supervision of a licensed Sewer and Drain Cleaner or Master Plumber.
Applicants shall provide proof of experience and reference letters, see WSSC Code Section 114.6.
Journeyman Plumbers exceed requirements for a Sewer and Drain Cleaners license. A Journeyman Plumber does not have to also register as a Sewer and Drain Cleaner.
Licensed Sewer and Drain Cleaners or Journeyman Plumbers who desire to own or represent a Sewer and Drain Cleaning business shall apply to become a Principal Sewer and Drain Cleaner. See Application procedures below.
