[movieman]

Hi guys I would be incredibly grateful if I could receive some pointers on how to search for a leak

At the moment the property is is two Storey as in ground and first and the bathroom is on the first directly below is the hallway and there is a brown discoloration coming through

Run all the taps and look for drips.

Push a thin screwdriver through the centre of the damage in the ceiling, from below. Find where the screwdriver appears above, then that should give you a clue where to look, though stains do not always appear directly below a leak, water can run along timbers.

If no obvious leaks, try wrapping toilet tissue around pipes, that will quickly identify the exact point of the leak.

The stain is elongated, so the leak is probably somewhere on pipework parallel to that.

If you draw some lines on the paper with water soluble ink then even if the paper dries out before you can check it the ink will have run when the paper was wet.
