Well Warranty Coverage in New Hampshire
Private well homeowners in New Hampshire can check eligibility for well pump and pressure tank protection coverage through Well Protection.
New Hampshire has one of the highest per-capita rates of private well use in the entire country — nearly half of all New Hampshire households rely on private wells as their primary water source. This is a function of the state's dispersed rural settlement pattern, its resistant granite bedrock that limits municipal water infrastructure expansion, and a long tradition of self-sufficient rural homeownership. When a well pump fails in rural Grafton, Carroll, or Coos County, there is no utility to call. The cost lands on the homeowner, and in New Hampshire's granite country, those costs can be significant.
Private Well Use in New Hampshire
Approximately 45 percent of New Hampshire households — one of the highest rates in the nation — depend on private wells. Well use is concentrated outside the Manchester-Nashua corridor and the Seacoast area, but even in many Seacoast and southern NH communities, rural residential parcels on private wells are common. The Lakes Region, the White Mountains, and the North Country are areas of particularly high well dependence.
New Hampshire sits almost entirely on granite and metamorphic bedrock — the ancient Appalachian geology that underlies all of New England. Wells in NH tap into fractures in this crystalline rock, drawing from a fractured bedrock aquifer system. These aquifers are productive enough for residential use, but the water picks up minerals and elements from the rock as it travels through the fracture systems. This geology is the source of two of New Hampshire's most significant well water concerns: arsenic and radon.
Common Well System Issues in New Hampshire
Arsenic and radon are the best-documented naturally occurring groundwater quality concerns in New Hampshire. NH has some of the highest rates of naturally occurring arsenic in well water of any state in the country, and elevated radon — which can be present in both water and air — is widespread. While these are water quality concerns rather than mechanical ones, many NH well owners have installed water treatment systems to address them, adding components to their overall well system that also require maintenance.
Hard water from crystalline rock aquifers is common across much of New Hampshire, contributing to scale buildup on pump impellers, pressure tank bladders, and check valves over time. NH's winters are long and cold, creating real freeze risk for above-ground well components, pump houses, and pipe runs from the wellhead to the home. A frozen and burst pipe in the middle of a January cold snap in Coos County is one of the more acute well emergencies a homeowner in the state can face.
What Well Warranty Coverage May Include
A Well Protection plan for New Hampshire homeowners may cover the repair or replacement of the well pump, pressure tank, pressure switch, control box, and related well electrical components when they fail due to normal wear and mechanical breakdown. Coverage does not include water quality issues (including arsenic or radon), freeze damage, or the well casing. A 30-day waiting period applies after enrollment.
Checking Your Eligibility in New Hampshire
Coverage is available to qualifying New Hampshire homeowners regardless of region. Eligibility is based on your well system's current operating condition. If your well is currently operational, you may qualify. The eligibility check is free and takes a few minutes.
