Common borehole pump problems and solutions are worth knowing before your water supply lets you down at the worst possible time.
One day the pump is working fine. The next, water pressure drops, strange noises start, or nothing comes out at all.
Most borehole pump problems come from electrical faults, clogging, wear and tear, or incorrect pump sizing. The good news is that most of these issues have clear, fixable solutions.
This guide walks through the most common borehole pump problems and solutions, so you know what to check before calling a technician.
Why Understanding Common Borehole Pump Problems Matters
A borehole pump is the heart of your water system.
When it fails, your entire water supply stops — whether it’s for your home, farm, or business.
Knowing common borehole pump problems and solutions helps you catch issues early, before they turn into expensive repairs or full pump replacement.
Common Borehole Pump Problems and Their Solutions
Problem 1: Pump Won’t Start
Causes:
- Power supply failure or tripped breaker
- Faulty control box or pressure switch
- Burnt-out motor
Solution: Check the power supply and breaker first. If power is fine, the control box or motor may need professional inspection or replacement.
Problem 2: Low Water Pressure
Causes:
- Clogged pump screen or filter
- Worn impellers
- Pipe leaks or blockages
- Undersized pump for the borehole’s yield
Solution: Clean or replace filters and screens. If pressure stays low, inspect the impellers and pipework for wear or leaks.
Problem 3: Pump Runs but No Water Comes Out
Causes:
- Water level has dropped below the pump intake
- Air lock in the pipe system
- Foot valve or check valve failure
Solution: Confirm the borehole’s water level hasn’t dropped too low. Release trapped air from the pipes and inspect the check valve.
Problem 4: Pump Cycles On and Off Frequently
Causes:
- Faulty pressure switch
- Waterlogged pressure tank
- Leaks in the system
Solution: Test and replace the pressure switch if needed. Check the pressure tank’s air charge and inspect the system for leaks.
Problem 5: Pump Makes Unusual Noises
Causes:
- Worn bearings
- Debris inside the pump
- Pump running dry
Solution: Turn off the pump immediately to prevent motor damage. Inspect for debris and have bearings checked by a technician.
Problem 6: Sand or Sediment in the Water
Causes:
- Damaged or poorly fitted screen
- Pump set too low in the borehole
- Aquifer instability
Solution: Have the screen inspected and reposition the pump if it’s set too close to the bottom.
Technical Specifications to Check
| Component | What to Check |
|---|---|
| Pump motor | Voltage rating matches power supply |
| Pressure switch | Cut-in and cut-out pressure settings |
| Pipe diameter | Matches pump output capacity |
| Foot valve | No cracks or debris blocking flow |
| Control box | No burnt wiring or loose connections |
Causes Behind Most Borehole Pump Problems
Most borehole pump problems and solutions trace back to a few root causes:
- Incorrect pump sizing — too small or too large for the borehole’s actual yield
- Electrical faults — power surges, loose wiring, or failing components
- Lack of maintenance — dirt, sediment, and wear building up over time
- Low water levels — pumps running dry due to seasonal changes or overpumping
- Old age — pumps naturally wear out after 8–15 years of use
Use Cases: Where These Problems Show Up Most
- Domestic homes — low pressure and cycling issues are most common
- Farms and irrigation — pump sizing problems are frequent due to high demand
- Commercial properties — electrical faults are more common with heavier daily use
- Solar-powered systems — power supply mismatches can cause starting issues
Maintenance Tips to Prevent Common Problems
- Schedule annual professional inspections
- Clean or replace filters and screens regularly
- Monitor water pressure for early signs of change
- Check electrical connections for wear or corrosion
- Avoid running the pump dry during low water periods
- Test the pressure switch and tank periodically
Common Mistakes While Operating a Borehole Pump
- Ignoring early warning signs like noise or pressure changes
- Running the pump dry during droughts or heavy usage
- Using the wrong pump size for the borehole’s yield
- Delaying maintenance until a full breakdown occurs
- DIY electrical repairs without proper training or safety checks
What to Do About Borehole Pump Problems
- Identify the specific symptom — no water, low pressure, noise, or cycling.
- Check simple causes first, like power supply and filters.
- Call a professional for electrical faults or motor issues.
- Consider pump replacement if repairs become frequent or costly.
Addressing common borehole pump problems and solutions early saves money and prevents total system failure.

FAQs
What are the most common borehole pump problems?
The most common borehole pump problems include low water pressure, frequent cycling, unusual noises, and pumps that won’t start.
Why does my borehole pump keep cycling on and off?
This is usually caused by a faulty pressure switch, a waterlogged pressure tank, or leaks in the system.
How do I fix low water pressure from my borehole pump?
Clean or replace clogged filters first. If pressure stays low, check for worn impellers or pipe leaks.
Why is my borehole pump making noise?
Noise often signals worn bearings, debris inside the pump, or the pump running dry — turn it off and inspect immediately.
How long do borehole pumps typically last?
Most borehole pumps last 8 to 15 years, depending on usage, water quality, and maintenance.
