This replaces the anode that came with your tank. Fits all brands. It is 44 inches long but can be cut to fit shorter water heaters.


  • The anode will keep your tank from rusting and breaking, while reducing or eliminating odor problems because of anaerobic bacteria found in some water that react with regular magnesium or aluminum anodes to produce hydrogen sulfide gas and a rotten-egg odor.
  • The tape will enable you to remove the anode in future to check it.
  • The sticker will help you remember when you installed it.


Socket wrench and 1 and 1/16-inch socket. For further details, check out the Tools page.

Are you ordering the right anode? This anode must replace the one that came with the tank or the smell won't go away. Make sure you have a hex-head rod in your tank and not a combo anode.

If you have any doubts about what you're ordering, be sure and e-mail your questions to us at mail@waterheaterrescue.com. We want you to order only what you need!

If you soften your water and have odor, consider a powered anode. The aluminum/zinc anode might not stop the smell. We don't want you to waste your money.
