  • pipe-thread seal tape
  • service sticker
  • instructions

This replaces the anode that came with your tank. Fits all brands. Heaters of 75 gallons and more usually have larger plumbing and this anode won't work in them.


  • 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.

The shopping cart generates an invoice and response, but we will give you delivery date and tracking information within a few days of your order by e-mail. We try to ship within one business day. If there is any hitch, we'll let you know immediately. If you hear nothing, consult your e-mail junk file. It's not uncommon for spam blockers to reroute our e-mails.


The products offered here are designed to make water heaters last longer, or solve specific problems. Installation is potentially do-it-yourself, but if you have the least doubt about your abilities, we suggest that you obtain expert help.

Remember also that if you have difficulties with installation, odds are that a professional or handyman will know a way to do it.

This product will not work in Rheem/Ruud/Richmond/GE water heaters made in 2005 or later. You'll have no water pressure.

Shipping is by UPS within the contiguous United States. UPS does not deliver to post boxes. Allow up to about a week for delivery. Canada, Hawaii and Alaska are only served by Priority Mail and can use a post box.


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 combo rod in your tank and not a hex-head anode. Nearly all Bradford Whites and some A.O. Smiths employ this configuration. Also tell us the brand of your heater.

If you are using a water softener, consider a powered anode. The aluminum/zinc anode might not stop the smell. We don't want you to waste your money.


Merchandise in original condition can usually be returned within 120 days for a full refund of the purchase price, not including shipping. E-mail mail@waterheaterrescue.com for instructions and authorization.
