There is a slow drip in my basement. Complicating factor--it seems to be coming from a gas pipe, not anything that should have water. It could be condensation but I don't think so. Many more details plus photos inside.
Went downstairs to find a drip coming from the basement ceiling. Enough water had dripped to soak three large boxes down one side and make the cardboard start tearing, so quite a bit of water. It seemed to drip a drop every 5-10 seconds.
I got up there to see what was leaking, and it is a long yellow pipe that seems to dip in spots, more like a hose than a pipe. Google tells me yellow = high pressure gas pipe. But the water seems to come from next to the pipe where it is pressed against a support beam. There is no water above that spot, and the entire beam has moisture spreading down.
Assuming that is the source of the water, it is then dripping onto a white PVC pipe, spreading out about 8-inches, and then falling to the ground.
Near this gas pipe IS a small, copper water pipe that provides water to our refrigerator above. But it is over 6-inches away from the wet beam, and the pipe bends BELOW the beam, so the water pipe in close proximity doesn't seem to be a logical culprit.
Now the next guess might be condensation but Dr. Google doesn't really tell me that gas pipes are prone to condensation. More, it's only happening RIGHT HERE at the baseboard. I walked the entire length of the pipe (about 40 feet or so) and there isn't any evidence of moisture except at this one spot...so I don't know why condensation would happen only at one point along a 40-foot pipe. The pipe is bone dry in the other spots so it's not like water is condensing along the entire pipe then just flowing along the pipe until it drips in the lowest point.
Some images are here in case they're any help:
Hoping the hive mind can help me diagnose and figure out who to call if repairs are needed (do plumbers do gas?)
