Man I've really been hogging this forum.

When we pulled up the carpet, there were a few damp spots on the floor. They haven't dried out yet [img]/forums/images/icons/frown.gif[/img]

The largest (3-4 sq feet) is near the wall (maybe the wall is leaking?) One is under a bathroom upstairs, but the ceiling has no water stain/damage. A couple are in the middle of the floor with out any probable water sources. I've checked the basement underneath for pipes.

Any ideas what is causing this? Could it be old pet stains? (doesn't smell like urine). Methods for hunting down leaks? Should I try to dry them out?
