My Well Pump Keeps Tripping the Breaker: 7 Powerful Fixes That Actually Work!
If you’ve ever gone to get water from your well only to find that my well pump keeps tripping the breaker, you know how frustrating it can be. A tripping breaker doesn’t just interrupt water supply—it could signal underlying electrical or mechanical problems that, if ignored, can lead to bigger expenses.
Fortunately, there are practical solutions to identify the cause and fix it before it turns into a serious problem. In this article, we’ll cover 7 powerful fixes that actually work, step by step.

Understanding Why My Well Pump Keeps Tripping the Breaker
Before jumping into solutions, it’s crucial to understand why my well pump keeps tripping the breaker. A breaker trips when the electrical circuit becomes overloaded, overheated, or detects a fault. In the context of well pumps, this usually happens due to:
- Electrical overload
- Motor issues
- Wiring problems
- Mechanical blockages
Identifying the root cause ensures you fix the problem correctly instead of just resetting the breaker repeatedly.

1. Check for Electrical Overload
One of the most common reasons my well pump keeps tripping the breaker is an electrical overload. If your pump is drawing more current than your breaker allows, it will trip to prevent damage.
How to Check:
- Locate the breaker panel.
- Identify the breaker connected to your well pump.
- Check the amperage rating on the breaker and compare it to the pump’s required amperage (usually listed on the pump label).
If the pump requires more amperage than the breaker can handle, consider upgrading to a higher-rated breaker or reducing the load by disconnecting other high-power appliances on the same circuit.
Tip: Always consult a licensed electrician before changing breaker ratings.
2. Inspect the Pump Motor
If your well pump motor is overheating, it can cause the breaker to trip. Motors can overheat due to age, worn bearings, or internal shorts.
Signs of Motor Problems:
- Humming noise without water pumping
- Excessive vibration
- Burning smell
Solution:
- Turn off the breaker and disconnect the pump.
- Check the motor windings with a multimeter for continuity.
- Replace the motor if resistance readings are outside the manufacturer’s recommended range.
Regular maintenance of your well pump motor can prevent sudden trips and prolong its life.

3. Examine Wiring and Connections
Faulty wiring or loose connections are another reason my well pump keeps tripping the breaker. Even a small short circuit can trip the breaker immediately.
Steps to Inspect:
- Turn off the power at the breaker.
- Inspect the pump wiring for signs of wear, corrosion, or loose connections.
- Tighten all terminal screws and replace any damaged wires.
Table: Common Wiring Issues and Fixes
| Issue | Symptom | Fix |
|---|---|---|
| Loose connections | Intermittent breaker trips | Tighten or replace terminals |
| Corroded wires | Visible rust or burn marks | Replace wires with proper gauge |
| Short circuit | Breaker trips immediately | Locate and repair insulation damage |

4. Check the Pump Pressure Switch
The pressure switch controls when the pump turns on and off. If it’s faulty, your pump may run continuously, causing the breaker to trip from overload.
How to Test:
- Turn off the power.
- Remove the cover of the pressure switch.
- Inspect the contacts for wear or corrosion.
- Replace the switch if contacts are pitted or not moving freely.
Properly functioning pressure switches prevent the pump from overworking and tripping the breaker.
5. Look for Mechanical Blockages
Mechanical blockages inside the pump or piping can strain the motor. Debris or sediment may restrict water flow, making the pump work harder and draw more current.
Steps to Clear Blockages:
- Turn off the pump and breaker.
- Remove the pump from the well (for submersible pumps) or check intake screens (for jet pumps).
- Clean out debris and inspect impellers for damage.
- Reinstall and test the pump.
Keeping your well and pump clean reduces mechanical strain and prevents repeated breaker trips.

6. Test the Well Pump Capacitor
Some pumps use a capacitor to help start the motor. A failing capacitor can prevent the motor from starting properly, causing high current draw and tripping the breaker.
How to Test:
- Turn off power.
- Remove the capacitor from the pump.
- Use a multimeter set to capacitance mode to check the rating.
- Replace the capacitor if it reads lower than the rated value.
Replacing a worn capacitor is often a simple and inexpensive fix that solves repeated breaker trips.
7. Upgrade the Breaker or Circuit
If all else fails and your pump is functioning normally, the problem may be an undersized breaker. Sometimes, older electrical systems cannot handle modern pumps efficiently.
Recommended Actions:
- Consult a licensed electrician.
- Upgrade the breaker to match the pump’s amperage requirements.
- Consider dedicated circuits for the pump to prevent overloading.
Table: Typical Pump Amperage vs Breaker Rating
| Pump Horsepower | Typical Amperage | Recommended Breaker |
|---|---|---|
| 0.5 HP | 4–6 A | 15 A |
| 1 HP | 8–10 A | 20 A |
| 1.5 HP | 12–15 A | 25 A |
| 2 HP | 16–18 A | 30 A |
Upgrading the breaker ensures the pump can operate without nuisance trips while maintaining safety.

Additional Tips to Prevent Breaker Trips
- Schedule regular maintenance of the well pump.
- Keep electrical panels and wiring dry and free from dust.
- Monitor water pressure and flow for early signs of strain.
- Replace worn parts promptly to avoid cascading failures.
By addressing the root causes rather than just resetting the breaker, you can maintain a reliable water supply and extend the life of your pump.
Conclusion
Dealing with a tripping breaker is frustrating, but it doesn’t have to be a mystery. If my well pump keeps tripping the breaker, the problem usually falls into one of seven categories: electrical overload, motor issues, wiring problems, pressure switch failure, mechanical blockages, capacitor issues, or undersized breakers.
