I had to put a gfi outlet outside of one of my customers house, no biggie,right? Well when I was taking my measurments inside the house, I noticed a heat line going to the 1st floor, in which I thought I had enough clearance. I proceeded to drill my holes, the first hole thru the brick with a hammer drill, then an auger bit thru the joist, up against the brick to get inside. The auger got stuck, so I pushed it a little. Don't you know I hit that heat line. It was so close to the to the holes that I drilled, that the whole heating system emptied into the driveway with not a drop of water in the basement! Lucky for me that my brother-in-law, who is a plumbing contractor, was in the area and he came out to repair it. Believe it or not!
