Plumbing conditions in New Hampshire
New Hampshire has long, cold, snowy winters. Many older New England homes with basements, private wells and septic systems.
Deep winter freezes are routine in New Hampshire. Pipes in exterior walls, crawl spaces, garages and unheated basements can freeze and split, and the leak often starts only when the ice thaws. Insulating exposed lines, keeping heat on in vacant homes and knowing where the main shutoff is are the best protection.
New Hampshire generally has soft to moderately soft water. Scale is less of a problem, but soft, slightly acidic water can be harder on older copper pipes, which can develop pinhole leaks over time.
