SR-03Check for pipes and cables, and know how to isolate themRun a cable and pipe detector over each marked spot before you drill. Detectors can miss things, so still drill carefully and stop at once if you feel resistance change or see dust that looks odd. Find your stopcock (usually under the kitchen sink) and check it turns freely, so you can shut the water off fast if you hit a pipe. If you have any doubt about what is behind the wall, turn the relevant circuit off at the consumer unit before you drill.
