Q: How often should a borehole pump be serviced in South Africa?
Borehole pumps in South Africa should be inspected annually under SANS 10252. Service includes flow rate measurement, water quality test (pH, iron, E.coli), motor current draw check, pump curve performance verification, and pressure switch inspection. SA load shedding causes repeated power interruptions that stress pump capacitors and motor windings. High iron content in Gauteng and KZN borehole water causes rapid impeller and seal wear. Catching these issues annually avoids extraction costs of R8,000–R25,000.
What the annual borehole pump inspection covers
✓Flow rate measurement — actual flow in litres per minute; decline indicates impeller or seal wear
✓Water quality test — pH, iron content, turbidity, and E.coli screen; iron over 0.3mg/l causes rapid internal corrosion
✓Motor current draw — operating current vs rated current; over-current indicates pump resistance from wear or blockage
✓Start capacitor check — most stressed component from load shedding cycling; measured and replaced if weak
✓Pressure switch calibration — cut-in and cut-out pressure verified; incorrect settings cause pump short-cycling
✓Pressure tank diaphragm check — waterlogged tanks cause pump to cycle every few seconds, reducing motor life dramatically
✓Surface pipework and fittings — non-return valve function and isolation valve operation

Load shedding and borehole pump damage
A submersible borehole pump is the most expensive and most difficult to access component in your home water system. Pump extraction from a 30–80m borehole costs R3,000–R8,000 before any repair. Load shedding imposes start-stop cycles on the pump motor that were never in the manufacturer's design specification. A capacitor rated for 2 restarts per day may see 10–15 restarts daily during extended shedding cycles.
Frequently asked questions
My borehole water is brown — is that serious?+
Brown or orange water indicates iron in the water (common in Gauteng and KZN) or pump seal wear allowing soil infiltration. Both require investigation. Book a service to quantify iron levels and pump condition.
Can a failing pump be repaired without extraction?+
Electrical faults — capacitor, control box — can be repaired at surface. Mechanical pump faults require extraction. Annual inspection identifies developing faults at the electrical stage before extraction is necessary.
What depth does HomeGuard Pro service?+
Surface and submersible pump systems to 100m depth. Boreholes deeper than 100m are referred to specialist drilling contractors.
Every HomeGuard Pro service is performed by an employed RCE Electrical & Plumbing Services technician — Home Affairs identity verified, SAPS background checked, PIRB or DOL trade qualified, and publicly liability insured.
