Southern NH Private Well Resources
A source-backed guide for homeowners trying to understand no-water, low-pressure, and well pump request situations around Merrimack and Southern New Hampshire.
This page is informational. It does not diagnose water-system problems or replace a qualified provider.
Do Many Southern NH Homes Use Private Wells?
Yes. USGS research with New Hampshire environmental agencies reports that a large share of New Hampshire residents use private wells, and that many private-well users are in southern counties including Hillsborough, Merrimack, and Rockingham.
What Should I Do If My Private Well Has No Water?
If your whole house has no water, write down what changed, whether the pump is silent or running, whether pressure returns at all, and whether there was a power outage or recent heavy water use. Avoid electrical work, exposed wiring, or unsafe pump/tank inspection. For a step-by-step local version, use the Merrimack private well no-water checklist. For a broader preparedness page that can be shared with Southern NH homeowners, use the Southern NH private well emergency checklist.
Is It The Well Pump Or Pressure Tank?
No-water and low-pressure symptoms can come from the pump, pressure tank, pressure switch, wiring, filters, well yield, or another system issue. A provider will usually ask whether the pump runs, whether the system short cycles, and what the pressure gauge shows if it is safe to view.
| Symptom | Possible Direction | What To Note |
|---|---|---|
| Whole house has no water | Urgent pump, power, pressure, or well issue | When it started, pump sound, breaker status if already checked safely |
| Low pressure throughout the house | Pressure tank, switch, pump, filter, or yield issue | Whether pressure drops during showers, laundry, or irrigation |
| Pump turns on and off rapidly | Possible pressure tank or switch concern | How often it cycles and whether pressure swings quickly |
| Pump runs constantly | Possible pump, leak, pressure, or well-yield concern | Whether water is flowing anywhere and whether pressure recovers |
