New Hampshire Plumbing Code, Statutes, and Rules
What this domain tests
How plumbing is regulated in New Hampshire: the statewide code and its amendments, the licensing structure administered by the Board of Plumbers within the Office of Professional Licensure and Certification, permits, inspections, and enforcement.
Core rules
- New Hampshire enforces one statewide plumbing code built on the International Plumbing Code with state amendments; local ordinances may be more stringent but cannot relax the state minimum. The exam expects you to know the code in the current rule book governs, not a remembered edition from another state.
- Licensing tiers: apprentice, journeyman, and master. A journeyman works under a master plumber; the master is the licensee responsible for permits, contracts, and the work performed.
- A plumbing permit is required before work begins, with rough-in and final inspections; work cannot be concealed before the rough-in is approved.
- Unlicensed practice, working outside the scope of the license, and failing to obtain inspections are grounds for discipline, along with code violations and abandonment of work.
- The Board adopts rules covering applications, examinations, experience requirements, renewal, continuing education, and disciplinary procedure, and it hears complaints and can suspend or revoke a license.
Worked example
A homeowner offers a journeyman cash to replace a water heater while the homeowner pulls the permit. That scenario has two failures: the journeyman is contracting plumbing work without a master's license, and the homeowner permit does not place the work under a responsible master. The compliant path is a master plumber pulling the permit, with the journeyman performing the work under that license.
Traps that cost marks
Assuming a local inspector may waive a state requirement; treating a journeyman license as authority to contract; starting work on a promise that a permit will follow; ignoring renewal and continuing-education deadlines.
