5 Common Bore Pump Issues and How to Fix Them

Bore pumps are essential for water access, especially in rural or agricultural settings. But when something goes wrong, it can disrupt everything—whether it’s watering crops, running livestock systems, or even basic household water needs. If you’re dealing with bore pump issues, knowing the common culprits and their professional fixes can save you time and stress. 

1. Low or No Water Flow

This is one of the most obvious signs of a problem. You turn on the tap or irrigation system, and nothing (or very little) comes out. It’s frustrating, but the underlying causes could vary widely.

• Blocked intake – Sediment, debris, or mineral buildup can clog the pump intake, restricting water flow.
• Worn impellers – The impellers inside the pump wear down over time, reducing their efficiency in pushing water.
• Low water table – If the water level in your bore drops below the pump’s intake level, the pump won’t work as expected.

A professional with experience in bore pump repairs Perth will start by inspecting the pump and intake for blockages or wear. If the water table is the issue, they might recommend lowering the pump or installing a new system designed for lower water levels. Attempting to fix this on your own could damage the pump further.

2. Pump Continuously Running

A bore pump that runs nonstop can lead to sky-high power bills—and it’s a clear sign something’s wrong. The usual suspects include:

• Leakage – A leak in the system means the pump is constantly working to replace lost water.
• Faulty pressure switch – If the pressure switch isn’t functioning correctly, the pump might not know when to turn off.
• Air in the system – This can cause the pump to lose prime and keep running unnecessarily.

A qualified technician will check the system for leaks, test the pressure switch, and inspect for air pockets. They’ll also recalibrate the system to ensure it operates efficiently, saving you from a nasty shock when the electricity bill arrives.

3. Frequent Cycling On and Off

Does your pump keep starting and stopping? This issue, known as short cycling, can quickly wear out the motor. It’s often caused by:

• Pressure tank issues – A failing or improperly sized pressure tank can lead to inconsistent operation.
• Electrical faults – Problems with wiring or the control box can interrupt the pump’s power supply.
• Blocked pipes – A partial blockage can create pressure fluctuations, causing the pump to start and stop frequently.

Short cycling is something you shouldn’t ignore. A professional can identify whether the issue is mechanical, electrical, or both, and repair or replace the necessary components. Proper maintenance and adjustments will also prevent this from happening again.

4. Noisy Operation

A bore pump should run quietly in the background, so loud or unusual noises are a red flag. Grinding, rattling, or humming sounds often point to:

• Worn bearings – Over time, the bearings inside the pump can degrade, leading to noise and reduced performance.
• Cavitation – This occurs when air bubbles form in the pump and collapse, creating a distinctive rattling or popping sound.
• Misalignment – If the pump or motor isn’t properly aligned, it can create vibrations and noise.

Rather than ignoring strange sounds, call in a professional as soon as you notice them. They’ll inspect the pump’s internal components and motor alignment, addressing the issue before it causes further damage.

5. Electrical Failures

Electrical issues are another common headache for bore pump owners. A pump that won’t start, trips the breaker, or sparks when running isn’t just frustrating—it’s potentially dangerous. Key culprits include:

• Faulty wiring – Loose or corroded connections can disrupt the pump’s power supply.
• Motor burnout – Overloading the pump or running it dry can cause the motor to fail.
• Control box failures – The control box, which manages the pump’s operation, can develop faults over time.

Because electrical repairs involve safety risks, this is one problem you should never try to fix yourself. A licensed professional will diagnose the issue and repair or replace the affected components. They’ll also ensure the pump is operating within its power limits to prevent future breakdowns.

Why Professional Fixes Matter

It might be tempting to tinker with your bore pump yourself, especially if you’re in a remote location. But DIY fixes can do more harm than good. Bore pumps are intricate systems that require specialised knowledge, tools, and parts to repair properly. A professional will not only resolve the immediate issue but also conduct a full system check to catch potential problems before they arise. This proactive approach saves you time, money, and frustration in the long run.

Additionally, most bore pump warranties require professional servicing. Attempting repairs yourself could void the warranty, leaving you liable for costly replacements.

How to Minimise Bore Pump Issues

While some problems are unavoidable, regular maintenance is the best way to keep your bore pump running smoothly. This includes routine inspections, cleaning, and checking components like the pressure tank, impellers, and electrical connections. A professional maintenance service will ensure everything is in top condition and help you avoid expensive repairs down the line.

You can also talk to your installer about monitoring systems that alert you to potential issues, such as low water levels or power irregularities. These systems can help you act quickly before minor problems escalate.

The Bottom Line: Keep Your Pump in Top Shape

Your bore pump is a critical part of your water supply system, and addressing issues promptly is key to its long-term performance. Whether it’s a blocked intake, an electrical fault, or noisy operation, professional repairs will ensure your pump works efficiently and safely. Regular maintenance and expert advice can help you avoid many common issues altogether.

If you’re experiencing any of these problems, don’t wait—reach out to a professional service. They’ll diagnose the issue, fix it properly, and get your water flowing again with minimal fuss. With the right care, your bore pump will provide reliable service for years to come.
