Ponding test: the floor waterproofing
We block the floor trap in the bathroom above and hold water on the floor for a set time, then check the ceiling below. If the ceiling gets wet with the pipes unused, the waterproofing under the tiles has failed. This is the most common cause in buildings older than eight to ten years.
Pressure test: the supply pipes
We isolate the concealed supply pipes and hold them under pressure. A drop in pressure means a leak in a hot or cold water line inside the wall or slab, often at a joint. These leaks tend to be continuous rather than only when someone showers.
Flow and dye tests: waste pipes and floor traps
Water with dye is run through the shower, basin and WC in turn. Coloured water appearing below points to a cracked waste pipe, a failed floor trap connection or a WC outlet seal. The colour tells us which fitting.
Why the order matters
Ponding first, then pressure, then flow. Each test isolates one system, so the finding is a fact, not an opinion. The report states which test confirmed the source and how confident we are, which is exactly what the management needs to write on Form 28.
Report it with photos and you get a case number immediately. We inspect both units and issue the written report your management needs.
