This kind of anode screws into the hot-water port and can either replace another combo rod or augment a hex-head anode. Fits all residential water heaters with 3/4-inch plumbing. Heaters of 75 gallons and more often have larger plumbing and if so, this anode won't work in them.

IMPORTANT: BEFORE YOU ORDER
If you contemplate adding an anode to a new tank, things have gotten complicated recently. The combo anode will not work in heaters made in 2005 or later by Rheem/Ruud/Richmond/GE.
Also, if there are two anodes in a tank, they need to be of the same metal. Otherwise, the magnesium rod will be consumed more rapidly in the presence of an aluminum one and you won't get as long a life. On the other hand, if the tank is five years old or more, having dissimilar metals is less of an issue, since the original one will likely be largely consumed.
All the lower-end heaters by A.O. Smith, American, State, Kenmore, Whirlpool and Maytag have aluminum anodes. We've thought about stocking aluminum combo rods, but we've preached against aluminum for 15 years and won't change now just to make a buck.
You still have the option of removing the aluminum hex anode that comes with the tank and installing two magnesium anodes. A plus is that ours are thicker than factory ones.
Also tell us the brand of your heater.
