Frequently asked questions

Do plumbers need a license in New Hampshire?
Yes. Plumbers are licensed by the OPLC Mechanical Licensing Board at trainee, journeyman and master levels, and gas work needs a licensed fuel gas fitter. Verify a license with the NH OPLC license lookup. See which NH contractors need a license.
Who installs a well pump?
Installing or replacing a well pump requires a pump installer license from the NH Water Well Board, even for licensed plumbers. Our radon and well water guide covers testing and treatment.
Can a homeowner do their own plumbing in NH?
RSA 153:36 lets owners do plumbing in their own single-family home and make minor repairs, as long as the work meets the state plumbing code. Gas work is much stricter, so hire a licensed pro for anything involving gas.
