Initially, we evaluate what has been communicated to us followed by a sight survey of the pool, deck, water features and equipment. The detection process starts with “dye testing.” This process is started at the water line of the pool, working first around the pool perimeter and then downward. The tile line is inspected for missing grout and/or holes. The skimmer is checked around the opening and inside the basket area. Many leaks occur in the skimmer where the plastic skimmer meets the tile grout. The pool jets or returns are thoroughly checked where the finish meets the plastic pipe.
