Locate the anode rod port on your water heater (refer to the water heater manual).
Use a ratchet wrench and 1 1/16-inch hex-head socket (or appropriate socket) to unscrew the anode head. In some water heaters, the anode head maybe below the surface. In this case, you may need to unscrew the tank cover and/or remove insulation foam before you can reach the anode head. |
