Plumbing conditions in New Hampshire
New Hampshire has long, cold, snowy winters with deep frost.
Many homes are older and rely on private wells and septic systems, and most have basements.
Hard freezes are a regular part of winter in New Hampshire, so pipes in exterior walls, garages, crawl spaces and attics need protection every year, and outdoor faucets and sprinkler lines must be drained before the first freeze.

Common plumbing problems in New Hampshire
Frozen and burst pipes
Cold snaps in New Hampshire freeze pipes in exterior walls, crawl spaces and garages. A frozen line often splits and leaks only after it thaws, so shut off the main if you see water.
Frozen pipe thawing →Private wells and septic systems
Many rural New Hampshire homes rely on private wells and septic systems. Pressure tanks, well pumps and septic lines need a plumber familiar with those systems.
Aging pipes in older homes
Older homes in New Hampshire often still have galvanized supply pipe, cast-iron drains or clay sewer laterals, which corrode, crack and collect roots with age.
Repiping →Basement backups and sump pumps
Many New Hampshire homes have basements, where the floor drain is the first place a sewer backup shows up and a sump pump is the main defense against groundwater.
