We came home from out-of-town to find a puddle of water in our basement. With the help of friends, we tried to locate the source but without success. The licenced plumber from Ben Huston used something like a medical stethoscope to detect a pinhole leak in the ceiling our our basement bathroom, directly above the shower enclosure. He was able to fix the problem promptly, using materials from his van and, although he had to cut a hole in the tiled ceiling of our shower enclosure, he left it in a state that was easy for us to repair.
