How To Replace The Anode Rod In Your Hot Water Heater

Quick guide on how to replace the anode rod in your hot water heater..

If you’re not much of a handyman you can of course ask a plumber to help out. However they will charge $100 for labour (give or take) – it really is a simple job on most brands of hot water systems and once you know what you’re doing it takes 5 minutes.

Here are the steps you need;

  1. Turn off the power/gas and water
  2. Drain some of the hot water using the drain valve on the side of your hot water system
  3. Take off the top covers using your Philips head screw driver to get to the top of the tank.
  4. Cut away some of the insulating foam if need be to get access to the top of the tank.
  5. Then use a 27mm socket (for majority of units) and a “breaker bar” – which just means a really long wrench to give you some leverage. Or you can put some piping or similar over your standard wrench to make it easier.
  6. Unscrew the old anode and discard
  7. Put some Teflon tape around the new anode thread and screw in securely.
  8. Replace covers and turn on power/water/gas
