Common Borehole Water Pump Problems
Pump Runs but Does Not Deliver Water
This can result from:
- Low borehole water level
- Blocked pipes
- Damaged impeller
- Incorrect pump installation
- Faulty check valve
- Air entering the system
- Pump operating outside its design conditions
The technician should establish whether the fault originates in the pump, rising main, borehole, electrical system, or water source.
Pump Does Not Start
A pump that does not start may have:
- Power-supply failure
- Damaged cable
- Failed capacitor
- Faulty control box
- Burnt motor winding
- Tripped protection
- Damaged pressure switch
Electrical testing should be performed before the pump is removed.
Low Water Pressure
Low pressure may result from pump wear, a blocked pipe, inadequate pump sizing, damaged impellers, falling borehole water levels, or problems within the distribution system.
Pump Overheating
Overheating can occur because of electrical faults, incorrect voltage, mechanical friction, inadequate cooling, bearing problems, or operating conditions outside the manufacturer’s specifications.
Frequent Electrical Tripping
Repeated tripping can indicate insulation failure, a short circuit, motor winding problems, excessive current draw, damaged cables, or other electrical faults.
The pump should not simply be reset repeatedly. Continued operation under fault conditions can cause more extensive damage.
Borehole Pump Repair Versus Replacement
Repair is generally preferable when the pump has a localized and economically repairable fault.
Replacement may make more sense when:
- The motor has suffered severe damage.
- The pump is excessively worn.
- Spare parts are unavailable.
- Repair costs approach the price of a replacement pump.
- The pump is incorrectly sized for the borehole.
- The pump has reached the end of its service life.
- Repeated repairs have failed to solve the underlying problem.
A qualified technician should compare the cost of repair against the expected remaining service life of the equipment.
How Borehole Pump Repair Is Carried Out
A professional repair typically follows these stages:
- Initial inspection – The technician establishes the symptoms and operating conditions.
- Electrical testing – Voltage, current, insulation, cable continuity, and control components may be tested.
- Hydraulic assessment – Flow, pressure, valves, pipes, and water delivery are checked.
- Pump diagnosis – The technician determines whether the pump itself is defective.
- Pump retrieval – Where necessary, the submersible pump is safely removed from the borehole.
- Component inspection – Bearings, seals, impellers, motor windings, cables, and other components are inspected.
- Repair or replacement – Damaged components are repaired or replaced.
- Reinstallation – The pump is correctly positioned and connected.
- Testing – Flow, pressure, electrical performance, and automatic controls are tested.
How to Reduce Borehole Pump Breakdowns
Preventive maintenance can significantly reduce unexpected failures.
Recommended practices include:
- Do not allow the pump to run dry.
- Monitor borehole water levels.
- Inspect electrical connections regularly.
- Install suitable surge and electrical protection.
- Keep control panels protected from moisture.
- Monitor changes in flow and pressure.
- Investigate unusual pump noise immediately.
- Clean filters and relevant water-system components.
- Schedule periodic pump inspections.
- Use correctly rated cables and electrical protection.
- Ensure the pump is correctly sized for the borehole.
