Most water heater tanks are steel with a thin glass lining to protect the metal from corrosion. Since the lining eventually cracks, tanks have a second line of defense against rust, a long anode rod that attracts corrosive elements in the water. When the rod itself becomes so corroded that it can no longer do its job, the tank soon rusts out, leaks and needs replacement. However, if you replace your anode rod before it fails, about every 2 years(A magnesium anode), you can double the life of your water heater.

Not detailed enough description! Faulty item.
Although the product was in fact for an RV water heater, it was straight threaded rather than tapered. Bought a 2-pack - completely unusable. Can not recommend because of this fact.
