Power outage no-water guide
Private Well No Water After Power Outage in Merrimack, NH
If your water did not come back after an outage, storm, generator switch, or breaker event, start with safe observations before requesting help.
Do not touch wet electrical equipment, exposed wiring, pressure switch contacts, or generator wiring unless qualified.
Short Answer
Many private-well systems depend on electric pumps, so a power outage can leave a home with no water if the pump, pressure switch, breaker, controls, or generator connection does not recover properly. The safest next step is to document what happened before anyone opens equipment.
What To Check Safely
| Question | Why it matters |
|---|---|
| Did power come back to the whole home? | A partial outage or generator issue can leave pump equipment offline. |
| Is the whole house without water? | Whole-house water loss points toward the well system or main supply. |
| Did a pump breaker trip? | Repeated breaker trips should be treated as a safety issue. |
| Is the pump silent, humming, or running? | Sound can help a provider triage power, control, pump, or pressure issues. |
| Did water return briefly and then stop? | That pattern can help separate pressure recovery from ongoing system trouble. |
Generator And Storm Notes
If the home uses a generator, note whether the well pump is included in the generator setup, whether other large appliances are running, and whether the issue started when switching between utility power and generator power. Do not modify generator wiring or pump wiring without a qualified electrician or provider.
When To Request Help Quickly
Same-day help may make sense if the home has no water, the breaker trips repeatedly, the pressure tank area is wet, controls smell hot, the pump will not shut off, or the home has urgent medical, infant, elder, or animal-care needs.
