High-quality magnesium anode rod made from magnesium AZ63-alloy which is non-toxic and entirely safe for the human body. Replace the anode rod in your Suburban hot water heater every season or every 2-3 months before it has fully corroded.
* Compatible with Suburban water heaters
* High-quality magnesium anode rod
* Prolong the life of your hot water heater
* Protects your tank better and lasts longer than aluminum/zinc rods.
These need to be replaced every 1-3 years depending on how often the tank is used. If you check your anode rod and notice that it's heavily corroded, then it's done its job of protecting your expensive tank, and it needs to be replaced.
The 4.5" x 1/2" NPT works with Atwood and Dometic water heaters, and the longer 9.25" x 3/4" NPT is compatible with Suburban water heaters.
