hi can anyone give me any advice, as i cant get i contact with my electrician with it being bank holiday weekend. Just installed a new kitchen and had to box in various pipes beneath the boiler. Before drilling the fixing holes for the boxing in i checked the wall with a electric charge and stud detector but it seemed to not pick anything up, then when i drilled through a loud bang and sparks! did'nt feel any electric shock and the drill is still working fine. Checked all the electrics in the flat appliances, mains etc and all working fine too. But when using the shower this moring i got several slight shocks which i can only describe as like static shocks which you get sometimes from door handles. Am at a loss at the moment as am waiting to tile the wall in the kitchen but don't want to start in case someone has to get in to remedy the problem and damage the new tiles. Any advice?
