Well Pump Not Working in Jacksonville? Common Causes and What to Do Next
Common Well Pump, Pressure Tank, and Electrical System Failures Affecting Jacksonville Homes

Few household problems are as frustrating as turning on a faucet and discovering there is no water. If your well pump is not working in Jacksonville, the cause could range from a simple tripped breaker to a failed submersible well pump, damaged underground well wiring, defective pressure switch, or a complete well pump motor failure.
At Davis Electric Services, we provide professional well pump troubleshooting, water well electrical repair, and well system diagnostics throughout Jacksonville and Northeast Florida. Our electricians routinely diagnose well pump electrical problems that leave homeowners without water pressure, no water service, or recurring breaker trips.
Why Your Well Pump Is Not Working in Jacksonville
A well water system depends on several electrical and mechanical components working together. When one component fails, the result is often no water from the well, low water pressure, or a well pump that won't turn on.
Common well system components include:
- Submersible well pump
- Deep well pump
- Jet pump
- Pressure switch
- Pressure tank
- Well control box
- Well pump breaker
- Underground well wiring
- Pump motor
- Electrical disconnects and controls
A failure in any of these components can cause a complete loss of water service.
Well Pump Breaker Keeps Tripping
One of the most common service calls we receive is for a well pump breaker that keeps tripping.
When a breaker trips repeatedly, it is usually protecting the electrical system from:
- Short circuits
- Ground faults
- Damaged underground wiring
- Burned well pump wires
- Well pump overload conditions
- Failing well pump motors
Many homeowners simply reset the breaker, only to have it trip again. While this may temporarily restore power, repeated breaker trips are usually a sign of an underlying electrical fault that should be professionally diagnosed.
Pressure Switch Failure and Pressure Tank Issues
The pressure switch controls when your well pump turns on and off based on water pressure inside the pressure tank.
A defective pressure switch can cause:
- No water pressure
- Intermittent water pressure
- Well pump not turning on
- Well pump running continuously
- Pressure fluctuations throughout the home
Pressure tank issues can create similar symptoms. If the pressure tank loses its air charge or becomes waterlogged, the pump may short-cycle, reducing pump life and increasing electrical stress on the motor.
Underground Well Pump Wiring Problems
Many Jacksonville homes rely on underground wiring to deliver power from the electrical panel to the well system.
Over time, underground well wiring can fail due to:
- Water intrusion
- Corrosion
- Rodent damage
- Landscape excavation
- Tree root movement
- Age-related deterioration
In many cases, we find that homeowners have power at the breaker but no power reaching the well equipment. Voltage testing and continuity testing often reveal damaged conductors hidden underground.
Underground cable failures are one of the most common causes of well pump electrical problems in Northeast Florida.
Diagnosing Well Pump Motor Failure
A failing well pump motor may show warning signs before complete failure.
Symptoms often include:
- Humming noises
- Excessive current draw
- Frequent breaker trips
- Reduced water pressure
- Pump starts and stops unexpectedly
- Complete loss of water
Professional well pump troubleshooting includes testing voltage, amperage, insulation resistance, and motor performance to determine whether the issue is the pump itself or another component of the system.
Well Pump Has Power but No Water
One of the most confusing situations for homeowners occurs when the well pump has power but no water is being delivered.
Possible causes include:
- Failed pump motor
- Damaged impellers
- Failed pressure switch
- Broken underground well wiring
- Defective well control box
- Loss of prime on jet pumps
- Low water table conditions
Proper diagnosis is critical because replacing a pump unnecessarily can cost thousands of dollars while leaving the real issue unresolved.
