A few days ago I noticed a slow leak coming from the ceiling molding in my basement. The basement is finished and there aren't any pipes directly above the molding as far as I know. The immediate thought was a dishwasher leak, since it's above and nearby but the drip doesn't seem to relate to its use, or the use of the kitchen sink, also above. Everything looks dry above, as far I can tell.
Any ideas where to look next to find the source? The ceiling area isn't near the outside of the basement so I don't think it's coming in from the outside. Although I'm a novice at home repair and don't have much experience with these things.
