The Tank Help confirming correct approach of rotten egg odor Reply To: Help confirming correct approach of rotten egg odor

Just for fun, though, you might consider pouring two pints of drugstore peroxide into the heater. One week doesn’t seem very long for it to be a stagnation issue, but since you haven’t had odor before, there is a slim chance that’s all it is. If the odor comes back, then yes, a powered anode.

Since you just bought the heater, you ought to remember whether it’s a six- or 12-year warranty. Only the latter is likely to have two anodes.

As to voiding the warranty, yes, if they find out you switched anodes. The reason, though, is that all the manufacturers’ policies are that any equipment they have not tested voids the warranty. That makes sense, since they don’t want add-ons causing trouble for them.

I’m working to get the anode tested and change that, though. The anode works fine and is a solution to odor that the manufacturers don’t offer. They really don’t have a viable solution to offer their customers who complain about odor after buying a new heater. A.O. Smith does have two or three high-end models with hard-wired powered anodes.

That said, they won’t know you put one in unless you tell them. Keep the factory anode somewhere so that if the tank proves defective, as some number do every year, you can put the anode back before turning it in, saving the expensive powered anode for the new heater.
