How to Find Leaks Around a Water Heater

When you inspect a tank, inspect all around the tank. Water dripping onto it can rust a tank from the outside in, nearly as fast as from the inside out. Equally important: If water is coming from somewhere, make sure it's really from the water heater before you rush out headlong to replace it. Possible culprits: drippy drain valves and temperature/pressure relief valves, rain down vents, even broken water pipes.
