A domestic water pump is the silent workhorse of your home, delivering a consistent water supply for drinking, cooking, cleaning, bathing, and gardening. But like any piece of equipment that runs daily, it can encounter problems over time. The good news? Most issues are common, predictable, and fixable, especially if identified early.

At Aqua Group, we have spent decades in designing, manufacturing, and servicing Texmo domestic water pumps that work reliably in Indian homes. Drawing on that experience, here is a guide to troubleshooting the most frequent domestic water pump problems.

1. Pump Not Starting at All

Possible Causes:

• No power supply or tripped circuit breaker
• Faulty wiring or loose electrical connections
• Malfunctioning Capacitor or control panel
• Burnt-out motor

Troubleshooting Steps:

• Check the power source and ensure the switch is turned on.
• Inspect Control Panel and reset if necessary.
• Examine visible wiring for damage; if unsure, call a qualified electrician.
• If the motor is burnt out, professional repair or replacement is necessary.

2. Pump Running but Not Delivering Water

Possible Causes:

• Airlocks in the suction line / Priming Issue
• Low water levels in the source
• Blocked foot valve or suction filter
• Worn-out impeller or damaged internal components

Troubleshooting Steps:

• Prime the pump by pouring water in the suction pipe line to remove air from the system.
• Check the water source to ensure there is a sufficient supply.
• Clean or replace clogged filters and foot valves.
• If mechanical wear is suspected, have the pump inspected by an Authorised service technician.

3. Low Water Pressure or Flow

Possible Causes:

• Clogged inlet filter or blocked pipeline
• Worn-out impeller
• Sediment buildup in pipes
• Voltage fluctuations affecting motor speed

Troubleshooting Steps:

• Check and tighten all foundation bolts, and realign the pump and motor to eliminate vibration.
• Listen for abnormal noise, check bearing temperature, lubricate properly, and replace damaged bearings or faulty motor components.
• Verify water level, clean suction strainer, reduce suction lift or pipe restrictions, and ensure NPSH is adequate.
• Inspect piping joints and gaskets for leaks, ensure suction line slopes correctly, test foot valve, and re-prime the pump.

4. Excessive/Unusual Noise or Vibration

Possible Causes:

• Loose mounting bolts or misalignment
• Worn out bearings or motor issues
• Cavitation (caused by insufficient water supply to the pump)
• Air in the suction line

Troubleshooting Steps:

• Tighten all mounting hardware and ensure proper pump alignment.
• Replace worn out bearings and lubricate moving parts where applicable.
• Maintain adequate suction head, keep liquid level high enough or lower the pump closer to the source.
• Remove airlocks by re-priming the pump.

5. Overheating

Possible Causes:

• Running the pump dry (no water)
• Continuous operation beyond the pump’s duty cycle
• Blocked cooling Fan cover or poor ventilation around the motor
• Voltage fluctuations causing motor stress

Troubleshooting Steps:

• Always check water levels before switching on the pump.
• Give the pump rest intervals if it is not designed for continuous duty.
• Keep the motor area clean and well-ventilated.
• Install a voltage stabilizer if your area experiences frequent fluctuations.

6. Leaks Around the Pump

Possible Causes:

• Worn-out shaft seals or gaskets
• Cracks in the pump casing due to impact or years of worn
• Loose plumbing connections

Troubleshooting Steps:

• Replace seals and gaskets as needed.
• Inspect for casing damage, repair or replace the affected part.
• Tighten all pipe fittings without over-tightening to avoid damage.

Preventing Common Pump Problems

While troubleshooting can solve many pump issues, prevention is always better. Here are some best practices to keep your domestic pump running efficiently:

• Regular Maintenance – Schedule periodic servicing to check Control Panel wiring, bearings, impeller condition, and seals.
• Proper Installation – Ensure pumps are installed by trained technicians following manufacturer guidelines.
• Voltage Monitoring– Use a control panel with overload protection, dry-run protection, and Voltage protection.
• Water Quality Monitoring – Keep sediments and debris out of the pump by using proper filters and cleaning them regularly.

When to Call a Professional

If your pump is still underperforming after basic checks or if the issue involves motor rewinding, internal repairs, or electrical troubleshooting, call a certified service technician. Attempting complex repairs without expertise can damage the pump further and void warranties.
