I’ve been drilling into walls for years and never once hit a pipe or electrical cable*, by following a bit of common sense. Check where radiators are. Never drill directly above or below an electrical socket or light-switch, those kinds of things…
but i dio the same and have drilled a cable, that was run diagonally accross a wall, and saw an electrician drill a stud wall, after checking with his detector, straight through a water main made from pdfe, blue plastic, then had a customer drill through his skirting board,and into the radiiator pipe hiden behind it, he didnt believe me the pipe went behind it, he thought he knew better, then there was the carpet fiter who drilled for the new threshold strip and went straight through the underfloor heating electric cable, thankfully it was off,but when it clicked in that night huge bang.Then there was a customer who was having sky installed, asked the sky man to borrow his long drill bit as i didnt have one,while we had a cup of tea, the customer drilled from outside to inside wall, and straight into the back of his radiator,
Can you pick me 6 numbers between 1 and 49 for this weeks lottery seeing as you have so much luck.
