Should be on both. There is a little rod of magnesium or aluminum/zinc inside the waterheater. This is called the anode rod.
It basically is a sacrificial corrosion item. Over time it will get eaten away to nothing. As long as it is in place and working, other parts of the interior of the heater will not corrode. If it gets too corroded though, it losses its effectiveness and will greatly reduce the efficiency and life of the heater. If it gets too corroded, it can even break off and fall, and then rattle around inside the heater, potentially cracking the interior lining of the heater. It also helps keep the odor down in the heater. Specially switching to an aluminum rod from magnesium. Softened water will corrode the anode rod quicker. It should be replaced a minimum of every 4 years. On 9/27/05, Dana <[EMAIL PROTECTED]> wrote: > not a clue. Didn't know I had any.
