AB-02Check for pipes and cables before you drillCables and pipes can run almost anywhere in a wall, not just in the 'safe zones' near sockets and switches. Run a detector over the marked spot, but still treat the wall as if something could be there — cheap detectors miss deep cables, armoured cable, and pipes behind thick plaster. Find your stopcock now (usually under the kitchen sink) and check it turns, 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.
