How to Prevent Common Submersible Pump Install Problems and When to Call a Pro

Quick answer (read this first)

• Verify correct bore size and sufficient depth for your pump model.
• Ensure all electrical connections are securely sealed and waterproofed.
• Protect the pump from sand and debris using appropriate filters.
• Confirm a stable and adequate power supply with robust earthing.
• Monitor for consistent water flow, pressure, and any unusual sounds post-installation.

Safety first

• Always disconnect the main power supply before starting any work.
• Wear insulated gloves, safety glasses, and appropriate footwear.
• Never attempt complex electrical wiring if you are not qualified; call a professional.
• Ensure proper earthing for all electrical components to prevent severe electric shocks.
• Handle heavy pump components and pipes carefully to avoid personal injury.

Tools you may need

• Multimeter for electrical testing
• Pipe wrenches, thread sealant, and Teflon tape
• Wire strippers, crimpers, and waterproof splicing kits
• Measuring tape and marker
• Strong lowering rope or cable for the pump
• Basic hand tools (screwdrivers, pliers)
• Bucket or container for water quality checks

Step-by-step

Step 1

Inspect Borehole Conditions: Verify the bore is clean, free of obstructions, and has sufficient depth and diameter for your specific pump model.

Step 2

Assemble Pump Components: Securely attach the discharge pipe, safety rope, and electrical cable to the pump head, ensuring all connections are taut and watertight.

Step 3

Prepare Electrical Connections: Carefully splice pump cables to the main power cable using proper waterproof kits, ensuring correct wire matching and insulation. STOP if unsure; call a professional.

Step 4

Lower Pump Carefully: Using the designated safety rope or lowering device, slowly and steadily lower the pump into the bore, ensuring it hangs straight without scraping the casing.

Step 5

Install Control Panel and Power: Mount the control panel in a dry, accessible location, connect the main power supply to it, and ensure a dedicated circuit breaker and robust earthing are properly installed.

Step 6

Prime and Initial Test: If required, allow the pump to prime fully. Briefly run the pump to check for immediate water flow, adequate pressure, and absence of unusual noises or vibrations.

Step 7

Monitor Performance and Adjust: After the initial test, continuously monitor the pump’s performance for several hours, observing consistent water delivery, stable pressure, and absence of leaks or abnormal operation.

Common mistakes

• Incorrectly sizing the pump for the borewell’s yield or the property’s water demand.
• Inadequate waterproofing and sealing of electrical splices, leading to short circuits.
• Poorly secured pipes or safety ropes, causing the pump to detach or drop into the bore.
• Operating the pump dry (without sufficient water), which can cause motor damage and overheating.
• Insufficient or improperly installed earthing, posing serious electric shock hazards.
• Using low-quality pipes, cables, or fittings that degrade quickly and lead to leaks or electrical faults.

When to call a professional

• When handling complex or high-voltage electrical wiring without prior experience or proper qualifications.
• If the pump fails to start, delivers no water, or shows significant pressure loss despite basic troubleshooting steps.
• For persistent electrical issues such as frequent circuit breaker trips, burning smells, or erratic power supply.
• When dealing with deep borewell drilling, casing installation, or complex pump extraction from significant depths.
• If you suspect serious mechanical failure, motor damage, or internal pump issues that require specialized tools and expertise.
