Water Heater Sacrificial Anode after 94 days use

[Wayne]

This anode was new before our winter trip. I am surprised how much of the sacrificial anode has corroded away in such a short time. The water in Arizona tastes like minerals so I'm guessing that's where most of the sacrificing happened. I will put this one back in and use it again.

Has anyone used a spray wand to remove the sediment from the tank? How much did you see come out?

Previous anode after about 100 days and the water heater sitting full during the warm months.

When do you replace the water heater anode?

This anode has been in use since Aug 1, 2021 and we have spent over 100 nights in the trailer since then. We don't drain the water heater in the warm months, so the anode is slowly being consumed, except when the trailer is winterized. Is this anode still serviceable or is it done?

I think the water is hard everywhere in Arizona. Our little 6 gal. water heater didn't have an anode and I discovered it didn't come with one and supposedly doesn't need it. I used a little spray wand in the heater and didn't get much out. A tip with a 90 degree bend or more to push anything out would work better.

I wonder why they say it doesn't need one? I would think the tank would be subject to corrosion like any other water heater.
