Leak detection in Pretoria — what we actually find
A Pretoria property with a climbing account and no visible leak usually has high pressure behind it, forcing water out of joints that would hold anywhere else. Testing static pressure at the meter is part of the detection here, not a separate exercise. Pool, irrigation and borehole plumbing added after the original installation is the other place we look first.
Property stock in Pretoria
Pretoria's older suburbs run higher municipal pressure than most of Johannesburg, and without a working pressure-reducing valve that pressure destroys geyser elements and mixer cartridges early. Summer storms overwhelm older gully traps that were never sized for the runoff. Electrically, pool pumps, borehole pumps and irrigation were usually added years after the original board and are where earth leakage tends to start.
Direct access on most freehold properties. Where a pressure-reducing valve or added pump circuit is involved, we test at the meter and the board rather than working from assumptions.

- High municipal pressure destroying geyser elements and mixer cartridges early
- Missing or failed pressure-reducing valves behind repeat leaks
- Older gully traps overwhelmed by summer storm runoff
- Pool, borehole and irrigation circuits added after the original board causing 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 Pretoria 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
