Had a leak in the corner of a tile shower and didn't discover it until it had been happening for some time and water dripped out of the ceiling in the basement (finished ceiling). There are membranes that can be put under the tile during construction - wish that was done but it wasn't...
No major damage though. I plan to seal the corners with flexible caulk instead of brittle grout. This is a common problem on tile corners it seems. But I would also like to put in an "early warning" sensor (or several). The shower is adjacent to a tub so I have some access under the tub and from the basement to put some sensors there and run the cables through the ceiling to the wiring closet close by.
Looking to determine a good sensor. I saw some posts on a "leaf wetness" sensor that is a pattern on a PC board but I would like something that presses up against the wood - I don't think I can position the PCB to reliably catch surface moisture. Maybe some sort of sponge with nails in it that would absorb surface water/moisture. I know that moisture level in wood can be determined by resistance between 2 nails an inch or two apart - that's basically how wood moisture meters work. Since it shouldn't normally be wet I don't have much concern about corrosion but I could use stainless hardware.
Any ideas or links?
