Warm damp patch spreading across a tiled kitchen floor
A Waterkloof homeowner noticed kitchen tiles that stayed slightly warm and never dried after mopping. Two plumbers had quoted to lift the entire floor to find it.
A thermal scan showed a hot plume tracking from the geyser feed across the slab. Acoustic listening confirmed the exact hiss point — a pinhole in the hot-water line, 1.1m from the wall.
One tile lifted instead of the whole floor. Owner saved an estimated R18 000 in unnecessary demolition.
