Leak detection in Rosebank — what we actually find
Detecting a leak in a Rosebank block means working out whether it belongs to your unit, the stack or the landlord's common infrastructure, because that determines who pays. A failed non-return valve high in the building can present as a leak several floors down. We test from the point where the tenant's installation begins, and set that boundary out clearly in writing.
Property stock in Rosebank
Rosebank is mostly apartments and light-commercial buildings, so access is usually the constraint rather than the plumbing or wiring itself. Stack pressure in the taller blocks means a failed non-return valve on one floor pushes water back into the units below. Commercial tenancies are metered per unit off a landlord's main, and years of shopfitting have left abandoned circuits live behind ceilings.
Booking the service lift and the building's plumber sign-in usually takes longer than the repair. We arrange both with the managing agent before the visit.
Faults that cluster in Rosebank
- Failed non-return valves letting stack pressure push water back into lower units
- Access and service-lift booking delaying otherwise short repairs
- Abandoned shopfitting circuits left live behind ceilings
- Unclear boundary between landlord's main and tenant's installation at COC time
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 Rosebank 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
