Leak detection in Johannesburg North — what we actually find
On large Johannesburg North stands the supply run to the house is long, buried and under an established garden, so a leak can water a lawn for months without ever surfacing. We section the line and pressure-test rather than dig for it. Where roots have already reached the sewer line, the same root activity is a good indication of where to test the supply.
Property stock in Johannesburg North
The established freehold suburbs of Johannesburg North sit on mature gardens with decades-old trees, and root intrusion into clay sewer lines is the single most common cause of the blockages we clear. Overhead municipal feeds are still common, so storm damage to a service connection presents exactly like an internal fault. Many homes still run the original 1970s mains cable, undersized for everything added since.
Mostly freehold with direct access. On larger stands we allow time to locate boundary stop-cocks and the point of entry before diagnosing.
Faults that cluster in Johannesburg North
- Root intrusion into original clay sewer lines under mature gardens
- Storm damage to overhead service connections mimicking an internal fault
- Original 1970s mains cable undersized for present-day loads
- Repeat blockages returning months after rodding because the pipe itself has failed
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 Johannesburg North 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
