I've seen some differing opinions. Our new to us Winnie is a 2000 and this is something that probably should be checked. I'm wondering what is the worst case scenario if I don't check it and do they REALLY work?

All input appreciated. In East Texas IT'S WET...but it's still a great day!

The worst case scenario would be a rusted out tank. Normaly the anode will last 3-4 years but I check it annualy when doing routine maintenance. It also helps to keep minerals from building up on the electric heating element and reducing its efficiency.

Is this an item that can be cleaned and reused or does it need to be replaced?

THANKS!

Hi Mike,

The anode material erodes over time. I'd replace it with a new one and monitor the loss of material on a yearly basis. Rate of loss depends on how many minerals are in the water supply. Where I live my house hold water heater anode needs replacement about every 18 months.

I replace mine every year and it usually needs it.

Whenever there are disimilar metals, and moisture...galvanic action takes place. It will consume the least noble metal. That's why sacrificial anodes are used. They get eaten away...so you cannot refurbish or clean one...it has to be replaced.

I'm guessing you would rather spend $12 on an anode than $225-$500 on a new RV water heater??

I replaced the rod in my home water heater about a year ago. My water heater is WAY past it's warranty date...and will probably last a very long time if I keep up with replacing the anode in it every 5 years or so.

Chump change maintenance.
Less than 5 minutes to check and change...$12 bucks.

The water heater should be drained anyway before storage and removing the rod is how the tank is drained.

YES, they do work, Are they needed, that depends, if you have an ATWOOD Heater, then NO you don't need an Anode Rod, (although they do make a rod for them) just something drain your wallet for no reason. If you have a Suburban water heater, you better have an Anode Rod, as was said, way cheaper than buying a new heater.
