What this video covers
The clip points at kitchen spots that never get inspected because something is always in front of them.
Under the sink, where a slow joint leak can run for months into a cupboard base. Behind the fridge, where the drip pan sits and collects standing water nobody empties.
The takeaway
Both are hidden by design rather than by accident. Pull the fridge out and empty the cupboard under the sink twice a year, and you catch the leaks that otherwise announce themselves as a smell.
