The electrician has come and gone.
The short was due to water collecting in the canopy for the track light. The fuse did not blow because the wall dimmer blew instead.
Now the interesting thing is our apartment is on the first floor, and there is no obvious water overhead. I noticed that there is water damage to the dining room ceiling as well which is next to the kitchen.
The question is, where did the water come from? The pipes don't need to be directly overhead. There can be a leak and the water flows over the ceiling.
I spoke to the upstairs tenant but they said nothing happened.
We had some wall board replaced in our bathroom last year due to water damage and at the time, the was no apparent leaks to the pipes upstairs.
The opinion of my contractor with the wall damage was that they had some kind of water spillage upstairs or let something overflow.
Since it was repaired, the wall has been fine. This would confirm the opinion of the contractor. If a pipe was leaking, and had not been fixed, it would continue to be leaking and we'd have water damage on that wall again.
I really don't know what to do. I have my heating guy coming today, to do maintenance to get ready for the winter and to check out the heating pipes. The closest water upstairs to the light that shorted is a radiator, and I have hot water heat. Perhaps there's a leak from the heating.
Sukie thinks that they had a spill upstairs and are embarrassed to tell us. Either that or they keep their dogs penned up in that space with 2 gates. The floors are wood, so if the dogs go upstairs, his theory is it came down.
Still, there is no proof and it is still a mystery.
The only thing I know is that leaks, once they start, continue until they're fixed. They don't mysteriously start and stop like they do here.
& it's your Anniversary... so......
