Best Swimming Pool Leak Detection in Dallas TX

Had a leak in bathroom. Plumber came out and checked the water pressure. He said there was no indication of a slab leak. He said that we should run the test anyways. Ran it and found nothing. Cut away a few holes in the drywall (which isn’t that big of a deal to find the leak). After not being able to find anything they charged me 275. Leaving me worse off than I started.I called another plumber. He came out and found the leak in less than 5 minutes. No need to cut drywall for diagnosis or repair.The owner called me to come out the next morning, only because I was not happy with the service I received. But I had already decided to go with the company that was able to find the leak for me.I’m out the $300 but I guess I learned my lesson.2 stars because it seemed like the owner wanted to make it right. But with an active leak that’s just too late.
