We have noticed a small wet spot on our rug, which happens to be next to a ceramic tile, near our entryway. The wet spot is about 3" from a closet, and on the other side of the back of the closet wall is our laundry room, with washer and dryer.
The grout on the tile next to the wet spot is darkened for about 3", probably from becoming wet from underneath? There is absolutely no standing water and the wetness is only in a small approximately 3" diameter area.
Does piping run in or under the cement slab? If so, and if a pipe is under the wet spot, how would a leak occur and how would it go UP into our carpeting instead of down into the ground/concrete?
Any help would be appreciated.
