Solid Hex-Head
Aluminum/Zinc Anode Rod

Overview and closeup of solid hex-head aluminum/zinc anode rod


  • a solid, hex-head aluminum/zinc anode rod (about 44 inches of overhead clearance needed). This anode is .75-inch-diameter.
  • pipe-thread seal tape
  • service sticker
  • instructions

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.

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.

We ship by UPS Ground to the Lower 48 states, and by Priority Mail to Alaska, Hawaii and Canada.


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 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.

If you have read our resources and still have trouble figuring out what you need, you can buy a consultation for $40 and we'll scope out your situation and make recommendations.
