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 your tank
is in good condition, this will probably be the last anode you
ever have to buy. For more on this, read What
Kills Water Heaters.
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. Click here
