Think about any time you’ve seen water leaking in a home in a television show, a cartoon, or a movie. Leaky pipes are not the most exciting event, until water is bursting up through a pipe, blasting right out of the sink handle, or filling up the home. It usually comes at one of the most inopportune moments, all at once.
Of course, plumbers know that leaks and other plumbing problems don’t usually act this way. Rather than a flood of water in your bathroom, you may only notice a slight drop in water pressure. But one of the worst signs of a potentially problematic plumbing system is a wet or dark spot on your walls or ceilings.
