BOREHOLE PUMP INSTALLATION AND MAINTENANCE – 0723763173
Reliable Borehole Water Supply Solutions
A dependable borehole water supply starts with the correct pump, a well-planned installation, and a maintenance programme suited to the system's operating conditions. Whether you need a pump for a home, apartment building, farm, school, hotel, commercial property, or industrial facility, choosing and maintaining the right equipment is essential for consistent water delivery.
Pro-Logic Technologies Limited provides technical support for borehole pump installation, maintenance, troubleshooting, performance checks, and related electrical and control-system services. Our focus is helping customers understand their water supply requirements and identify practical solutions for their installations.
A borehole pumping system is made up of several connected components, including the submersible pump, motor, rising main, electrical cable, control panel, valves, sensors, and water storage or pressure equipment. Each component must be suitable for the intended application.
An incorrectly selected pump may deliver insufficient water or place excessive demand on the borehole. Poor cable sizing, unsuitable protection devices, leaking pipework, and defective controls can also contribute to recurring failures.
Professional borehole pump installation and maintenance helps establish a suitable operating arrangement and provides a basis for monitoring the system throughout its service life.

SELECTING THE RIGHT BOREHOLE PUMP
Pump selection should begin with an assessment of the borehole and the water demand of the property.
Borehole depth and water level
The total drilled depth is important, but it does not determine pump selection by itself. The static water level and pumping water level provide additional information about the vertical lift and the conditions under which the pump will operate.
The pump must remain adequately submerged during operation, in accordance with the manufacturer's requirements and the borehole design.
Required flow rate
Flow rate describes the volume of water delivered over a specified period. A domestic property may have a different requirement from a farm, apartment development, or commercial facility.
The required flow should be estimated from actual demand, storage capacity, and the expected operating schedule. The pump's performance curve should then be checked to establish whether it can deliver that flow at the required head.
Total dynamic head
Total dynamic head includes the vertical lift from the pumping water level, the pressure required at the destination, and losses caused by friction in pipes, valves, fittings, and other components.
A pump that produces high flow under low-head conditions may deliver considerably less water when the total head increases.
Electrical requirements
The pump motor must match the available supply voltage, frequency, and phase arrangement. Cable sizing, earthing, isolation, and protective devices must be selected according to the motor specifications, cable length, installation conditions, and applicable electrical requirements.
Water quality
Sediment and abrasive particles can affect pump performance and component life. Where water contains sand or other suspended material, the cause should be investigated and the pump selected and installed according to the water conditions and manufacturer's guidance.
PROFESSIONAL BOREHOLE PUMP INSTALLATION
Correct installation helps protect the pump and supports reliable operation.
Preparing the borehole
Before installation, review the borehole records where available and confirm the borehole dimensions, casing arrangement, water levels, and recommended pump-setting depth.
The installation should account for the position of the borehole screens, the required pump submergence, and any minimum clearances specified by the manufacturer.
Inspecting the equipment
Check the pump, motor, cable, rising main, fittings, and control equipment before installation. The equipment should be compatible and free from visible damage.
Where the pump and motor are supplied separately, assembly must follow the manufacturer's instructions.
Installing the rising main
The rising main transports water from the pump to the surface. It must be suitable for the expected flow, pressure, installation depth, and mechanical loads.
Joints should be assembled correctly, and the arrangement should support the weight of the water-filled pipe without transferring inappropriate loads to the electrical cable.
Securing the pump cable
The electrical cable should be secured using suitable cable guards or fastening arrangements. It must be protected against abrasion, pinching, and damage while the pump is lowered into the borehole.
Submerged cable joints, where necessary, must be suitable for the installation conditions and assembled using approved methods.
Lowering and securing the pump
Use suitable lifting equipment and safe handling procedures to lower the pump and rising main. The pump must not be suspended by its electrical cable.
Once the equipment is positioned, secure the borehole head and arrange the delivery pipework and cable entry to protect the installation against damage and contamination.
Completing the electrical installation
Connect the pump through appropriate isolation, control, and protective equipment. Verify that the wiring arrangement matches the motor specifications and manufacturer's diagram.
Electrical work should be completed by qualified personnel using appropriate safety procedures.
TESTING AFTER PUMP INSTALLATION
A newly installed pump should be tested before the system is accepted for normal operation.
Flow-rate measurement
Measure the volume of water delivered over a known period. Record the result together with the operating conditions so that it can be compared with the expected pump performance.
Pressure checks
Measure delivery pressure at a suitable point. Interpret the reading alongside the flow rate, elevation, pipework, and system requirements.
Electrical measurements
Where appropriate, record supply voltage and motor current and verify that the protective devices are correctly selected and functioning as intended.
Water-level monitoring
When required, measure the static and pumping water levels to assess drawdown and determine whether the pumping rate is appropriate for the borehole conditions.
Control-system testing
Verify that tank-level switches, pressure controls, protective shutdowns, and other installed controls operate correctly according to the system design.
Recording commissioning results
Record the pump model, installation details, measured flow, pressure, relevant electrical readings, and any observations. These records establish a useful baseline for future maintenance.
BOREHOLE PUMP MAINTENANCE SERVICES
Maintenance should focus on the complete pumping system rather than the submerged pump alone.
Inspecting the control panel
Check the accessible control panel for signs of moisture, overheating, damaged components, and loose connections. Verify the operation of relevant protective devices and control functions.
Checking pipework and valves
Inspect accessible pipework for leakage, damaged fittings, and signs of pressure loss. Check that valves operate correctly and that restrictions are not reducing delivery.
Monitoring flow and pressure
Record flow and pressure at suitable intervals. A gradual reduction in output may indicate developing pump wear, pipe restrictions, leakage, or changes in borehole conditions.
Reviewing electrical performance
Where suitable equipment and procedures are available, compare electrical readings with the motor specifications and previous records. Investigate abnormal readings rather than assuming they always indicate a particular fault.
Checking tank and pressure controls
Verify the operation of tank-level controls, pressure switches, transducers, and pressure vessels where installed. Frequent pump cycling should be investigated because it can increase wear and energy consumption.
Planning pump removal when necessary
Not every problem requires the pump to be extracted. Surface equipment and controls should be checked first. Pump removal may be appropriate when evidence indicates an internal mechanical or motor fault, or when further inspection is necessary.
COMMON BOREHOLE PUMP PROBLEMS
Pump fails to start
Possible causes include a power-supply failure, tripped protection, faulty contactor, defective control switch, damaged cable, or motor fault. A systematic electrical and control-system assessment helps identify the cause.
Pump operates but delivers little water
Possible causes include worn pump components, excessive drawdown, pipe restrictions, leakage, or unsuitable operating conditions. Flow, pressure, and water-level measurements help narrow down the fault.
Pump repeatedly trips
Repeated trips may indicate overload, cable damage, motor insulation failure, supply problems, or incorrect protective-device settings. The system should be isolated and assessed by a qualified technician.
Water pressure fluctuates
Fluctuating pressure may be associated with leaks, control problems, changing demand, a pressure-vessel issue, or an unsuitable pump operating arrangement.
Tank fills slowly
Slow filling can result from reduced flow, a restricted inlet, leakage, changes in water level, or increased delivery head. Measuring actual flow helps establish whether pump performance has changed.
Sediment appears in the water
Persistent sediment may be associated with borehole conditions, excessive pumping, unsuitable pump placement, or other changes in the water-bearing formation. The cause should be investigated to reduce the risk of pump wear and water-quality problems.
INSTALLATION AND MAINTENANCE FOR DIFFERENT APPLICATIONS
Residential properties
Homes require dependable water for daily activities. Maintenance should include checks of pump operation, tank controls, accessible pipework, and the pressure or storage arrangement.
Apartments and residential estates
Larger developments may require higher flow, multiple storage tanks, pressure zones, or standby equipment. The pump and control system should be assessed against the property's actual demand.
Farms and irrigation systems
Agricultural installations must account for irrigation flow, operating pressure, distribution losses, water storage, and the borehole's sustainable yield.
A pump should not be selected solely to maximise output if the borehole cannot sustainably supply that volume.
Schools, hotels, and institutions
These facilities may experience substantial variations in water demand. Commissioning records, scheduled inspections, and suitable backup arrangements can help manage the consequences of a pump failure.
Commercial and industrial facilities
Industrial systems may supply production equipment, cooling systems, cleaning facilities, or other essential processes. Maintenance should reflect the importance of the water supply and the consequences of interruption.
REPAIR OR REPLACE A BOREHOLE PUMP?
The decision depends on the nature of the fault, the pump's condition, the availability of compatible components, and the expected reliability after repair.
Repair may be suitable when the fault is identifiable and the affected components can be restored reliably. Replacement may be more practical when the pump is extensively damaged, unsuitable for the required duty, or repeatedly failing.
The assessment should also consider the rising main, cable, control panel, valves, and borehole conditions. Installing a new pump without addressing the underlying problem may lead to repeated failures.
The replacement pump should be selected according to the required flow, total dynamic head, sustainable borehole yield, and electrical supply.
