Why Water Pumps Stop Working

1. Power Supply Issues

The most basic and most overlooked cause.

• Tripped circuit breakers
• Faulty switches or wiring
• Damaged power cables
  
• Voltage drops common in rural WA

Before assuming pump failure, confirm stable power. If power is fine and the pump still won’t start, the issue is mechanical or hydraulic.

2. Loss of Prime

A pump that has lost prime cannot move water.

Common causes:

• Air leaks in suction lines
  
• Low water levels in tanks or wells
  
• Cracked pipes or loose fittings

This is extremely common in Perth, Mandurah, and regional WA properties using bore or tank systems.

3. Blocked or Clogged Pump Components

Sand, silt, leaves, scale, and debris are pump killers.

• Blocked impellers
• Clogged filters or strainers
• Sediment buildup from bore water

Once internal components are clogged, DIY fixes usually fail. This is where a professional water pump service saves time and money.

4. Worn or Damaged Pump Parts

Pumps are mechanical systems. They wear out.

• Failed seals
• Worn bearings
• Corroded impellers
• Shaft misalignment

WA’s mineral-heavy water accelerates wear, especially in agricultural and mining environments.

5. Pressure Switch or Controller Failure

If your pump turns on and off constantly or doesn’t turn on at all the controller may be faulty.

• Pressure switches stuck open or closed
• Electronic controllers damaged by heat or moisture

This is common in domestic pressure systems and irrigation setups.

6. Incorrect Pump Size or Installation

A pump that is incorrectly sized or poorly installed will fail early.

• Undersized pumps overwork and burn out
• Oversized pumps cause pressure instability
• Incorrect pipe sizing restricts flow

This is why professional pump selection and installation matters.

What You Can Check Before Calling a Water Pump Service

You can safely check the following:

✔ Power supply and circuit breakers
✔ Water source levels (tank, bore, dam)
✔ Obvious leaks or loose fittings
✔ Blocked filters (external only)

If the problem isn’t immediately visible, stop. Running a faulty pump causes irreversible damage.

When to Call a Professional Water Pump Service

Call a professional immediately if:

• The pump runs dry
• Electrical components are involved
• You hear grinding or metal noises
• The pump overheats
• The system services commercial, industrial, or mining operations

Why Professional Water Pump Servicing Matters in WA

WA conditions are brutal on pumps:
• High temperatures
• Abrasive bore water
• Long duty cycles
• Remote installations

Professional servicing ensures:
• Correct pump sizing
• Longer system lifespan
• Reduced downtime
• Compliance with safety standards

Cheap fixes cost more long-term.

Preventing Future Water Pump Failures

The smartest move isn’t repair it’s prevention.

• Schedule routine water pump servicing
• Install proper filtration
• Monitor pressure and flow regularly
• Replace worn parts early

Regular maintenance dramatically reduces emergency call-outs and system failures.
