How often should I replace the water heater anode rod and are they pretty much all the same when it comes to purchasing one? Thanks

On my last fw I replaced mine with a plastic plug.

It all depends on water quality and the quantity used. I replace when it is about half depleted or the wire looks weak near the fitting.

This is the first RV that I’ve had that has an anode rod our other campers/motorhomes just had a plug. I took the anode rod out to drain the water heater and I thought it looked pretty ate up after only one season. Is this normal?

This is a good method. According to Suburban you should drain the heater when not in use, so plenty of opportunities to check it. The rods are cheap as is teflon tape around the threads, and I suppose Suburban has a good reason for using them in their water heaters.

Yes. I consider replacing it just a part of annual maintenance. And this is my first MH with a Suburban heater. All the others were Atwood. This will also be my last MH with a Suburban.

If you have a suburban WH you MUST have an anode rod. If not your tank will destroy it'self. Anode rod is sacrificial. you wanna spend $15 or $300.00

Weak at the fitting is not a problem. When it all looks a think as a pencil it's time to change.

Yes. Change if the rod looks like a pencil. Atwood is SS and needs no rod. Suburban is glass line steel and need an anode rod.

Atwood is aluminium. needs no rod. Suburban is glass lined steal and must have a rod.You must drain the water in the winter to prevent freezing and breaking the tank.
