Leak detection in Sunninghill — what we actually find
The Sunninghill leak we find most often is not in a wall at all — it is a toilet cistern weeping continuously into the pan, silently, in a complex where nobody hears it. It is the most commonly missed leak anywhere and it is trivially confirmed with dye. We check that before bringing acoustic equipment out, because it is free to test and it is frequently the answer.
Property stock in Sunninghill
Sunninghill is dominated by townhouse complexes and office parks built through the 1990s and early 2000s. That means shared walls, shared drain runs and geysers sitting in roof spaces above living areas — so a failure that would be a nuisance in a freehold home becomes a ceiling and a neighbour's ceiling here. Most units are now at the age where the original geyser and its valves are all due together.
Complexes here almost always require the managing agent to be notified for anything touching a common drain or a shared wall. We arrange that before the visit rather than on the day.
Faults that cluster in Sunninghill
- Roof-space geysers over living areas with inadequate or blocked drip-tray drainage
- Shared drain runs where one unit's blockage surfaces in another
- Original 1990s and 2000s geysers and valves all reaching end of life at once
- Overflow pipes discharging into the roof void instead of outside
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 Sunninghill 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
