    What if the pool’s underground plumbing leaks?

    I know it's an old thread but did you find your leak? A couple thoughts for you based on my recent experiences: - Do you have a hydrostatic relief valve? Could it be letting water out? - In my area, American Leak Detection (a franchise company) charges maybe $450 to try to find your leak...
