Anode rods are a cheap way to protect an expensive water heater tank. This magnesium rod attracts the corrosive elements in your water supply, letting the rod corrode away instead of the steel tank walls — and it's sized specifically for Atwood-style 10-gallon RV water heaters.
Checking and replacing the anode rod on a regular schedule is one of the simplest maintenance steps you can take to extend the life of your water heater.
Swap it out at the start of the season or whenever the rod is visibly eaten away.
