My cottage is on well water. Several years ago we started with the dreaded sulfur smell, hot water only. I had a plumber replace the anode. Smell came back eventually. I found the model of the anode he installed and see that is just aluminum. Seems like the one I need is aluminum/zinc?

Has anyone had success with the aluminum/zinc ones and is it worth a shot?

Water heater is 9 years old but only used 7 months. a year. A friend said probably need a new tank.

I see they have these electric anodes that come highly rated. But pricey.

Let me know what you have experienced.

Thanks Ron
