I was drilling the holes for a shower screen when water shot into my face... I had hit a pipe that supllied the electric shower. I had checked using the pipe/wire detector and it had found nothing. Luckily i have DIY accidental damage cover, but i now have a shower screen i cannot put up as i will still need to drill fixing holes. Once the pipe is repaired could i put a batton in the wall, repair plaster and re-tile then screw into the batton using shorter screws? Any advice would be greatfully recieved. Thanks
