Also very good advice, but possibly a little misleading.

Cathoid or sacraficial rods have impurities that are left behind, so when the rod is "half" gone, it could be next to useless. It would be prudent to replace the rod anytime you notice significant deterioration. They are not that expensive, and a whole lot cheaper than a new water heater.

I definitely jumped the gun on replacing it, it looks like the 25%. Like one of the posters said, I'll keep the old one, just in case. I paid $14 at a local RV dealer. I can't tell you how much I appreciate this forum. I subscribe to other forums(non-RV type) and this by far is the most educational, helpful and friendly.

The $15 from Amazon for an anode rod is definitely cheaper than a complete water heater replacement.

This is assuming a Suburban water heater. If one has an Atwood model, it has a different design, so no need for one.

Just make SURE to use either Teflon tape or pipe goop designed for potable water systems on the threads. Else, they will corrode-weld into place.

Hello. Remember that an Atwood water heater should NOT have an anode rod installed. Atwood will not authorize warrantee work on one of their water heaters that has an anode rod installed.
