We are in the final days of our IG pool build. We filled the raised hot tub today and did not fill the pool yet as they are making a quick repair on the plaster tomorrow. This evening we saw water coming from the outside wall of the hot tub going into the pool. We have a lueder stacked spillway...could the water have found a route under the top stone and has worked it's way behind the stones? What would the next step be? I'm worried to death they'll have to tear the whole thing apart. Is this common? The water in the hot tub is on tile except at the spillway where it is on the stone. We haven't even turned the pool on yet. Thanks for any insight.
