I have an electric tank water heater. I can hear what sounds like water hammer in the walls behind it. It occurs anywhere from a few seconds to a few minutes apart. Even with no water running and I live alone. This has been happening for about 12-18 months. When I turn off the water going into the water heater it stops immediately. With the water back on, and the breaker open it continues, even after using up all the hot water left in the tank. Any ideas what this could be?
