Leak detection in Randburg — what we actually find
The diagnostic question in Randburg's older homes is which tap weakened first, because galvanised pipe weeps behind plaster long before anything shows. The furthest fitting fades first, and that tells us which run to test. In a bulk-metered complex, detection matters even more, since the water lost is being paid for by every owner in the scheme rather than by the unit leaking it.
Property stock in Randburg
Randburg's older freehold homes around Ferndale and Blairgowrie still have galvanised supply pipe in the walls, and once it starts weeping the pressure drop shows at the furthest tap first. Complexes here often share a single bulk meter, which makes one unit's internal leak everyone's problem. A high proportion of homes have been converted into offices or back rooms, each conversion adding load to a board sized for a family house.
Freehold access is direct. On bulk-metered complexes we coordinate with the managing agent, because isolating to test a single unit affects the others.

- Weeping galvanised supply pipe showing first as weak flow at the furthest tap
- Bulk-metered complexes where one unit's leak lands on everyone's account
- Boards overloaded by home-office and back-room conversions
- Sub-boards feeding cottages and outbuildings without their own earth leakage
How leak detection works
The meter test tells you whether you have a leak; detection tells you where it is. Close every tap, note the reading, wait two hours and read again — any movement means water is escaping between the meter and your fixtures. From there, acoustic correlation and thermal imaging locate it precisely enough to repair without opening tiles speculatively. That precision is the whole point, because the repair is usually small and the exploratory damage is what costs.
- Acoustic and thermal detection on supply lines, including under slabs and paving
- Toilet and cistern dye testing, which finds the most commonly missed silent leak
- Irrigation, pool and buried supply-line isolation testing
- Written reports with marked locations for insurance and municipal leak adjustments
- Repair of the located leak, or re-routing where the buried run is at end of life
Our process on a Randburg call-out
- 1Confirm an active leak with a meter isolation test before any equipment comes out
- 2Isolate zone by zone — toilets, irrigation, pool, house — to narrow the area
- 3Pinpoint with acoustic correlation and thermal imaging
- 4Mark the location and report it in writing with the position recorded
- 5Repair with a targeted break-out rather than exploratory demolition
