RV Water Heater Anode Rods

Anode rods are a proven way to protect the water heater's tank from internal corrosion. Made of magnesium or aluminum, an anode has a lower electrochemical potential than a steel tank and can shield it through the process called galvanic corrosion, when low-voltage current comes from the anode to the tank. Gradually, the anode is ruined; it sacrifices itself to keep the tank in good condition. But when the anode is almost consumed, corrosion starts to eat away the tank. To prevent it from happening, don't miss the time when the anode should be replaced.

Its service life depends on its material and water hardness, and many experts recommend checking this part visually at least once a year. Therefore, you will see how long it lasts and know which material works best. While magnesium models are usually the most reactive and effective in all cases, aluminum ones can serve much longer in harder water while providing adequate protection as well. Besides, the market offers zinc anodes which, in fact, are made of aluminum alloy with a portion of zinc to combat the smell of sulfur in the water.
