Plumbing isn't particularly hard although it can be very hard work. However, I would disagree that the worst that can happen is a leak.
Case in point. Here where I live in the Dominican Republic, they often use PVC pipe for electrical conduit as well as water plumbing. The conduit does usually have thinner walls, but looks pretty much identical. It works fine....
One day I was rerouting some outdoor "plumbing" so I could put in a garden. I pulled out my handy dandy PVC cutters (a tool nut unlike pruning shears) and proceeded to cut through one of the pipes.
Of course, as you have already guessed, this one was not a water line, but a live electrical line. I was standing on fresh garden soil and just happened to be wearing rubber sandals (I am usually barefoot). Had I been barefoot, it is quite possible I wouldn't be writing this post since I had a grip on the cutters that wouldn't have permitted me to let go.
So, do think before you cut.
Also, remember that water leaks and electricity don't mix well. Know how to shut off your power in the event of a disaster including flooding around the electric shutoff. If all else fails, you should be able to break the seal on your meter and pull it out of the socket. The electric company won't send you and cards of gratitude though and the electrical connections in the socket will be live on the incoming side.
