The shower arm springs a leak behind the wall. The first time I can understand since it was pretty old and got pitted and corroded. The second one is only a year old and split open right where it goes into the elbow. Both times it wrecked the living room ceiling below. This time is actually much worse since I drained more than half a bucket of water out of the ceiling before I started ripping it down.
So how can we prevent this in the future? It's a standard plumbing installation in the wall. I use Teflon tape and turn it hand-tight. I looked around and all the hardware stores sell the same crap.
The up side, if you can call it that, is that I'm getting pretty good at drywall work.
