AB-04Do your safety checks before drillingCables and pipes can run almost anywhere, not just in the 'safe zones' — a detector helps but can miss deep cables, metal conduit, or wiring behind metal-backed board. Treat every hole as if something could be there until you've drilled a little and checked. Find your stopcock now (usually under the kitchen sink) and make sure it turns, so you can shut off water fast if you hit a pipe. If you're at all unsure, isolate the relevant circuit at the consumer unit before drilling.
