A friend of mine rented a new apartment and asked me to help with some shelves. We will need to drill some holes for screwing the shelves.
One of the places has a electrical socket near by and the water for the washing machine.
I am really worried that we either hit the plumbing or the power cables. I was wondering if there is any (formal or informal) rule / good practice about plumbing and electrical cabling on the walls that sets the approximate height of each? Is there any other advice that we can follow to avoid a big mess?
