Powered Anode Combo, CerAnode

For Water Heaters With Combo Anodes Such as Bradford White and Some States and A.O. Smiths

  • a powered anode
  • pipe-thread seal tape
  • instructions
  • a galvanized steel tee
  • a 3-inch PEX-lined steel nipple
  • a 4-inch PEX-lined steel nipple

This replaces the combo anode that came with your tank. Fits all brands of all sizes of glass-lined steel residential heaters with 3/4-inch ports and a combo anode in the hot port of the heater and hanging straight down. If a tank is larger than 80 gallons, tell us. The anode may need some adjustment of its output. This is for use with Bradford Whites, and some A.O. Smiths and States.

Don't use in stainless steel or galvanized tanks, or the A.O. Smith Vertex. Not recommended for multi-anode indirect heaters.

IMPORTANT! If you have an electric water heater made after April 2015 by A.O. Smith, Lochinvar, State, Kenmore, Reliance, American, Maytag or Whirlpool, let us know because you'll need a pipe nipple longer than four inches.

The anode will keep your tank from rusting and breaking, while alleviating 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.

In water heaters with softened water but no odor issues, it provides a permanent replacement for sacrificial anodes, which are often consumed rapidly in softened water and thus, require frequent replacement.

It IS possible to use in any heater, but if you replace a sacrificial anode in a tank without a softener in hard water, we strongly recommend also putting in a sediment flush kit -- and actually flushing the heater every six months. Sediment buildup can bury the bottom of the heater, cutting it off from the anode's protection.

If you have a vacation cabin where the water heater sits idle, it may be that, no matter what anode you put in it, the water will still smell bad. We don't want you to buy a powered anode if it won't solve your problem. You might do better to replumb your water heater to allow hydrogen peroxide to easily be added. That WILL solve the problem.

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.

Prices include shipping by UPS Ground. Allow up to about a week for delivery.


This anode must replace the one that came with the tank or the smell won't go away. If your tank has two anodes, the second one must also be removed.

If you have a power vent heater, the power connector will stick up 4-5 inches above the top of the tank and may prevent reinstallation of the vent housing.

If you install this device in a way significantly differently from the instructions and intended use, you may void the warranty. Contact us if you have an unusual installation problem, or any doubt at all, and we can probably help.

If you have read our resources and still have trouble figuring out what you need, you can buy a consultation for $30 and we'll scope out your situation and make recommendations.
