AB-03Check for pipes and cables before you drillRun a cable and pipe detector over the marked spot, but still treat the wall as if something is there until you have real reasons to think otherwise — detectors miss cables that are deep, in metal conduit, or outside the normal safe zones near sockets and switches. Find your stopcock now, 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 at all, isolate the relevant circuit at the consumer unit before drilling.
