How do I replace an Electric Anode Rod in an Electric Water Heater?

Follow these steps to fix your issue:

  1. Shut off the electricity

    The two house circuit breakers are dedicated to the water heating system. You should wear gloves to protect your hands.

  2. Drain the water heater

    The water supply needs to be turned off. Attach a garden hose to the drain valve at the bottom of the unit and run it outside. The relief valve on the water heater can be opened. After opening the drain valve, close the drain valve and remove the garden hose, you will be able to drain 5 gallons of water from the tank.

  3. Remove the anode rod

    Remove the plastic cap from the water heating unit. The foam insulation on the anode rod needs to be removed. Pull the anode rod out of the tank after removing it from the thread.

  4. Install the new anode rod

    Wrap the threads of the anode rod with tape. Attach the new rod to the tank. Put the plastic cap back in.

  5. Fill the tank with water

    Allow the tank to fill with water by turning on the cold water supply. The hot water faucet should be turned off when the water starts to flow.

  6. Restore power

    The circuit breakers should be flipped to ON.

Time required:

15 minutes.

You would need the following tools:

needle nose pliers, pipe thread sealing tape, ratchet, work gloves.
