New Hampshire plumbing FAQ
How do I check a plumber's license in New Hampshire?
The New Hampshire Mechanical Licensing Board, under the Office of Professional Licensure and Certification, licenses plumbers.
Do pipes freeze in New Hampshire?
Yes, regularly. New Hampshire winters freeze pipes in exterior walls, crawl spaces, garages and attics, and outdoor spigots that aren't frost-free. Keep the heat on, disconnect hoses in fall and know where your main shutoff is.
Is New Hampshire water hard?
Generally soft, based on national hardness mapping, but it varies by utility and by well. Your water provider's annual water quality report lists the hardness for your system, and a plumber can test well water.
How old are homes in New Hampshire?
Census estimates for New Hampshire put 29% of homes as built before 1960, 23% from 1960 to 1979, 29% from 1980 to 1999 and 18% in 2000 or later. Older homes are more likely to have galvanized supply pipe and cast iron or clay sewer lines.
