Now if you are in the newer section of the villages, run your irrigation and go to the area closest to your shower and see if the sprinkler head is working properly. I have seen the sprinkler heads pop off and the stream of water goes into the soffit, and then gets into the house.
Hope this helps, let us know what you find.

Not so.
