AB-02Check for cables and pipes, and find your stopcockRun a cable and pipe detector over the wall along your fixing line, but don't rely on it completely — detectors miss cables that are deep, in metal conduit, or behind metal-backed plasterboard. Kitchens often have pipework running up to taps and sockets near worktop height, so treat the whole area with caution. Before you drill, find your stopcock (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, turn off the relevant circuit at the consumer unit before drilling.
