A Master Plumber can design, install, construct, replace, service, repair, alter, or modify the pipes, fixtures, and other apparatus used for bringing the water supply into a building and removing liquid and water-carried wastes from a building. A Master Plumber can also install and connect gas piping.
You need a Master HVACR or Master HVACR Restricted license in addition to a Master Plumber license if you design, install, construct, maintain, service, repair, alter, or modify a product or equipment including gas piping in heating and air conditioning, refrigeration, ventilation, or process cooling or heating systems. See Master HVACR and Master HVACR Restricted Licensure for more information.
The application asks you to select whether you are applying by examination or reciprocity. Whether you are applying by examination or reciprocity determines the types of documents you are required to submit.
In the state of Pennsylvania, Plumbing licenses are not issued by a state board. If the only current license you hold was issued by a Pennsylvania municipality or other jurisdiction, you must apply by examination.
These requirements apply to both reciprocity and examination applications.
The following requirements apply to applications by examination in addition to the requirements in the Requirements for All Applicants section above.

|IF you…||THEN these proofs are required:|
|have a Journeyman Certificate||Submit:

When you pass the By-Pass Exam (score of 70% or higher), send the official copy of the exam results to the Board office.
The following requirements apply to applications by reciprocity in addition to the requirements in the Requirements for All Applicants section above.
If none of the jurisdictions where you hold a current license has licensure standards that are “substantially similar” to those of Delaware, proof of experience is required. The table below shows whether to submit proof of experience.
