Hidden leaks often reveal themselves through unexplained increases in your water bill, wet spots on floors or walls, the sound of running water when all fixtures are off, or patches of unusually green grass in your yard.
Check your water meter when no water is being used in your home. Wait an hour and check again—if the reading changed, you likely have a leak somewhere in your system.
Don’t ignore these warning signs. The EPA estimates that the average household wastes nearly 10,000 gallons per year from leaks, and hidden leaks can run for months before being discovered. By then, you’re not just dealing with the leak itself, but potentially mold, structural damage, and insurance complications that could have been avoided with early detection.
