Mysterious water spot between slab and flooring

[rubytue]

It looks like it was the freezer afterall. We pulled it out and noticed there was a slight drip from the drain line. Not sure how it was getting under, but not over. But I am hoping we solved it. I like this much better than the idea of leaks in the slab. Keep your fingers crossed that this was it.

Every time I read about water leaks I think of a story one of my brothers told me. He was in the carpentry/building business his entire life and was a top trouble shooter for the largest local builder for years.

He was sent to a car dealer to find a water leak. The water was staining the ceiling tile in one office and starting to drip onto the floor below. The space between the ceiling and roof was about 4 feet so working up there was a pain, literally.

He spent two days tracking the water and finally started working on the roof where it was getting in. The owner of the dealership saw him and started yelling at him because he was working at the other end of the building from the damaged ceiling. The guy went in and called my brothers boss and raised Hell about it. His boss came out, was shown what my brother found, and told the dealer to let him do his job.

Turns out the water was coming in where the dealer had hired some cheapo day labor bunch to work on a drain. They didn't seal the area properly and the water, after getting through the roof was running across three separate steel beams before dropping of the edge of one and onto the ceiling tile.

The dealer paid an "annoyance" fee over and above the cost of the job.

80 feet that water ran before dripping onto the ceiling!

I had a similar problem with carpeting on a concrete slab. I suspected a plumbing or water mains leak somewhere but there was no evidence. The center of the carpet started getting an increasingly wider wet patch from what proved to be a crack in the slab and water was seeping in from the ground. It was scraped out, filled, sealed and the carpet relaid. Cost a couple hundred dollars. No problems since for nearly 9 years.

I was going to suggest the freezer as I looked at the first pic and read thru..

We have a water cooler, and one day while cleaning near it, I dropped a butter knife and my kitchen tile broke, and when we inspected further, noticed the subfloor was all rotted and deteriorated. The washing machine was fine, dishwasher too. It was then that we moved the water cooler and found that it had been leaking....no water on top of the floor though.

We had to chip up half our kitchen tile, relpace the subfloor and retile...
