We have the tru-tile system (pool installed 2009) and have a leak that we cannot locate. What do you recommend to repair? So far we have recaulked stairs and skimmers, resealed inside lights and tested the tile line (where liner snaps) for leaks. It will leak down to the bottom of the tile. Can we remove the tile or will that damage the track? Thinking of removing tile at track seams and reselling those. We are in need of any information you can provide - our pool dealer no longer installs or repairs these!
