CH-02Check for cables and pipes before you drillRun a detector over each marked point - cables and pipes can run almost anywhere in a wall, not just in the usual safe zones. Even with a clear reading, treat the wall as if something could still be there. 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, isolate the relevant circuit at the consumer unit before drilling.
