I have noticed the odd drip of water coming out of one of my master bathroom electrical sockets. When I removed the socket cover I noticed that it was quite damp inside, a little bit of mildew under the cover plate and the immediate drywall a little damp around the socket area. This wall is an exterior wall with wooden/hardy plank siding on the outside. Any ideas where the water could be coming from? I thought perhaps that I could have a leaky pipe since the pipes to the bath and basins are on the same wall, however the wall socket is a couple of feet higher than the faucets. I also thought that perhaps water was coming through the siding of the house and building up moisture in the wall which was being released into the house via the electical socket - it is the only electrical socket in the room against an exterior wall, all the other electrical outlets are on interior walls. I wondered if it was just bathroom moisture accumulating in that spot, but the other electrical sockets have no such moisture accumulation. Any help in trying to figure it out would be appreciated.
