Water Levels. Setting levels for building foundations. I have used an age old method for setting levels using basic materials that generally are at hand. The method is using water in a garden hose and the principle is water seeks it's own level. It is very accurate way of setting levels, as accurate as the thickness of your pencil line and skill.
