AC-03Check for pipes and cables before you drillAiring cupboards often have hot water pipes running close to the walls, so run a detector over your marked lines before drilling anything. A detector helps but does not guarantee safety, so still treat the wall as if something could be there. Find your stopcock now, usually under the kitchen sink, and check it turns freely so you can shut the water off fast if you do hit a pipe. If you have any doubt at all, isolate the relevant circuit at the consumer unit before drilling.
