I'm a little OCD when it comes to traveling. I have learned from experience that when I am away, I constantly have visions that a pipe in the wall had burst and that the water is slowly filling the house. Having been through this enough times, I am tempted to put my worries to rest by simply turning off the main water line (in the garage) before we leave. My new fear with doing this, of course, is that I will cause something else bad to happen.
So I am curious, is it bad to turn off the water and drain the pipes prior to leaving for a week? In addition, what other precautions should I take aside from turning down the water heater? A few details - our house is two story, copper pipes, and we would be traveling in the spring time so temperatures in the house would stay at around 70 F.
