Had that in an upstairs toilet. No washbasin just the bog and the

Hi Alan,

My wife was the problem on this one. The result was the same as your
condensation. I found out that when she cleaned the room she was wiping the
light switch with a wet cloth. The water was collecting inside the switch
and as you said resulting in tracking to live. When you operated the switch,
a film a water was wiped out on the under side of the switch and connected
your finger to llive.
