A hissing sound like a running tap has revealed a leak somewhere under our tiled kitchen floor or possibly tiled hallway/downstairs toilet. There is no visible evidence of a leak, just the noise, which the plumber says shows there is a leak in one of the pipes connected to the mains (noise stops when water turned off). We cannot access the pipes unless we dig up the floor, units etc (aaarghh!). To make matters worse, there is underfloor heating down there too... The plumber professes himself baffled and says he doesn't know if any equipment that would allow him to locate the leak more precisely. He says pipe-sealing products only work on heating systems and this is definitely an issue with the mains. Help! Any advice or similar experiences?
