I have a hot water slab leak which is found behind my bathroom vanity. We heard the noise for a week but never saw any water. Just today we saw water starting to come up under the vanity. I found the leak, my question is is it ok to run the hot water just long enough to take a shower? Does it just go under the slab? I was going to fill concrete hole with caulk to keep it from coming up. Just need hot water for day or two until plumber can arrive.
