As a standard process during a snagging inspection, we check for internal and external leaks present / potential issues in the future. A few examples from a recent inspection below shows externally the cavity tray was positioned incorrectly as the weep holes were too high, all downpipes weren't connected properly, blocked gutter trays and air bricks were at ground level.
Internally, whilst there was no immediate sign of leaks, the moisture meter raised a clear reading around the ensuite partition wall. Having ruled out the potential of the nearby radiator leaking with a thermal camera (showing the pipe ran away from the area) it prompted the suggestion of the toilet waste pipe.
...This last example is a good reason alone to have us conduct a new build snagging inspection in haste of flooring being laid; this would have not been as obvious and would have damaged the floor covering too.
