Most water mains are now plastic, but if your house is pre-war like mine, the original disused iron main still exists somewhere. I found the old pipe in 2 neighbour's gardens, and connected a 1KHz signal to each end. I then searched my garden with a multi-turn loop for maximum signal. Digging down 4 feet I found the pipe. I then made TWO connections to it, filing the pipe clean, using 2 jubilee clips, and covering the lot with grease & tape. The idea of 2 connections is that you can always check continuity with an AVO to make sure BOTH are still connected to the pipe.
