Water Mystery

I went down into the basement for some tools tonight and heard a strange dripping sound. I thought this was interesting so I got a flashlight and went to investigate expecting a broken pipe. I found dripping water coming right through the floor not around any pipes. I then traced out what I was under and figured it was in the kitchen and went upstairs to check it out. Sure enough I found water dripping out of the hot water radiator, someone had loosened the release valve a little and water was slowly dripping out. I was able to tighten it up and clean up the mess, one good thing it was certainly cheaper and faster than having to fix a broken pipe.
