Well Pumps
Well Pump Troubleshooting: A Safe, Ordered Checklist
A homeowner-safe troubleshooting checklist for well pump problems, focused on the simple checks you can make before calling a professional.
By Know Your Well Water Editorial TeamReviewed October 29, 20262 min read
Quick Answer
When a well pump acts up, start with the safe, simple checks: confirm power is on, check the breaker, look at the pressure gauge, and listen for the pump running. Reset a tripped breaker once. If it trips again, or if the fix involves wiring, the pressure switch, or pulling the pump, stop and call a licensed professional — those are not DIY repairs.
Safe checks you can make
Start here
- 1Confirm other appliances have power so you know it is not a whole-house outage.
- 2Look at the breaker for the well pump. If it is tripped, reset it once.
- 3Read the pressure gauge — note whether pressure is zero, stuck, or fluctuating.
- 4Listen: can you hear the pump or the pressure switch clicking when you open a tap?
- 5Check for obvious leaks around the pressure tank, switch, and visible plumbing.
The breaker rule
Reset a tripped breaker only once. If it trips again, there is an electrical fault or a stalled motor. Do not keep resetting it — call a licensed professional.
What the symptoms suggest
| Symptom | Possible direction | Who handles it |
|---|---|---|
| No water, no pump sound | Power, breaker, switch, or motor | Reset breaker once, then a pro |
| Pump runs constantly | Leak, lost prime, worn pump, bad switch | Pro diagnosis |
| Rapid on/off cycling | Waterlogged tank or wrong pre-charge | Check tank; pro if unsure |
| Sputtering air at taps | Low water level, leak, or lost prime | Pro diagnosis |
| Sand or grit in water | Over-pumping or screen issue | Pro assessment |
When to call a professional
- The breaker trips more than once.
- The problem is in the pressure switch, control box, or wiring.
- The pump may need to be pulled from the well.
- You see sand, lose prime repeatedly, or lose pressure you cannot explain.
- You are unsure — a pro can test things you cannot safely reach.
Keep water safe meanwhile
If a well problem lets in contamination or you lose the sealed wellhead, treat the water as suspect until it is tested. Routine testing follows EPA and CDC guidance for private wells.
Frequently asked questions
- My pump has no power — what should I check first?
- Confirm the home is not in a general outage, then check the pump breaker and reset it once. If it immediately trips again, stop and call a professional; that points to an electrical or motor fault.
- Can troubleshooting damage the pump?
- The safe checks above will not. Repeatedly resetting a tripping breaker, running a dry pump, or opening energized components can cause damage or injury, so those steps belong to a professional.
