When to Replace Your Well Pump: 8 Warning Signs
8 Warning Signs of Pump Failure
1. No Water
- Complete failure—pump doesn't run or produce water
- Could be pump, electrical, or well issue
- Requires immediate diagnosis
2. Low Pressure / Flow
- Gradual decline in water pressure
- Pump running but delivering less
- Sign of worn impellers or motor struggling
3. Rapid Cycling
- Pump turns on/off frequently
- May indicate bad pressure tank OR pump issue
- Causes motor wear and higher electric bills
4. Running Continuously
- Pump runs but never shuts off
- Can't build pressure
- Worn pump or leak in system
5. Strange Noises
- Grinding, clicking, or squealing
- Motor or bearing problems
- Submersible pumps are underwater—noise travels through pipes
6. Air in Water
- Sputtering faucets
- Could indicate pump set too high or dropping water level
- Or crack in drop pipe
7. High Electric Bills
- Sudden increase in electricity cost
- Pump working harder than normal
- Motor running inefficiently
8. Sand or Sediment
- Particles appearing in water
- Pump may be drawing from too low
- Or well screen deteriorating
Average Pump Lifespan
Submersible Pumps
| Condition | Expected Life |
|---|---|
| Ideal conditions | 15-25 years |
| Average conditions | 10-15 years |
| Harsh conditions (sand, minerals) | 5-10 years |
Jet Pumps
- Average: 8-12 years
- Above ground = easier service but exposed to elements
What Affects Lifespan
- Water quality: Sand, sediment, minerals cause wear
- Cycling frequency: More starts = more wear
- Proper sizing: Oversized pumps cycle excessively
- Electrical: Voltage fluctuations damage motors
- Installation quality: Proper setup matters
Repair vs Replace Decision
When to Repair
- Pump less than 7-8 years old
- Problem is external (control box, wiring, pressure switch)
- First failure of the pump
- Repair cost under 40% of replacement
When to Replace
- Pump over 10-12 years old
- Second or third major repair
- Repair cost exceeds 50% of new pump
- Pump is undersized for current needs
- Motor is burned out
The 50% Rule
If repair costs exceed 50% of replacement cost on an older pump, replacement usually makes more financial sense. You get a new warranty, modern efficiency, and peace of mind.
What's Usually Repairable
- Control box (3-wire systems)
- Pressure switch
- Wiring issues
- Check valve
- Pressure tank (separate component)
What Means Replacement
- Burned motor
- Severely worn impellers
- Shaft or seal failure
- Motor drawing high amps
Cost Comparison
Typical Repair Costs
| Repair Type | Cost Range |
|---|---|
| Pressure switch | $150-$300 |
| Control box (3-wire) | $200-$400 |
| Pull pump + diagnose | $300-$600 |
| Minor pump repair | $400-$800 |
Replacement Costs
| Well Depth | Pump + Labor |
|---|---|
| Under 100 ft | $1,200-$2,500 |
| 100-200 ft | $1,800-$3,500 |
| 200-400 ft | $2,500-$5,000 |
| 400+ ft | $4,000-$8,000+ |
Long-Term Savings
- New pump warranty (typically 5 years)
- Better efficiency = lower electric bills
- Avoid emergency repair costs
- Opportunity to upgrade (constant pressure, etc.)
Frequently Asked Questions
How long does a well pump last?
Submersible: 10-15 years average, up to 25 with good conditions. Jet pump: 8-12 years. Depends on water quality and proper sizing.
Should I repair or replace my well pump?
Replace if: over 10 years old with major problem, repair costs over 50% of new, or multiple recent repairs. Repair if younger and problem is external.
Can I replace just the motor?
On submersible pumps, motor and pump are usually replaced together—labor to pull pump is the major cost. Jet pump motors can be replaced separately.
How do I know my pump is dying?
Warning signs: declining pressure, frequent cycling, runs constantly, high electric bills, strange sounds, air or sediment in water.
Does homeowner insurance cover well pump?
Standard homeowner policies rarely cover well pumps (wear and mechanical failure). Some offer additional riders. Check your policy.
