Eleventree 2 Pack RV Water Heater Anode Rods, Anode rod for RV hot water heaters,Replacement Suburban Part 232767-3/4"NPT threads 9.25 length-Magnesium

1.How does the anode rod work?

We all know that the iron tank will be eroded by oxygen and water or other corrosive elements. And the increase in temperature will accelerate this reaction. 

If your water heater has installed a anode rod, the rod instead of your tank will be corroded. The principle of this reaction is that magnesium metal is more active than iron.

2.Why should I replace the anode rod?

Your water tank would be corroded faster when the anode rod has been consumed. The tank is in danger of leaking water and you are in danger of being shocked!

3.How long does the anode rod need to be replaced?

1~2 years. It depends on the concentration of metal ions in water, the temperature, the contact area of water and exposed iron, the model of your water heater, and so on.

4.What is the difference between magnesium anode rods and aluminum anode rods?

Magnesium rods are more active than aluminum rods. It means that magnesium rods will be corroded faster but work & protect better.

Safety warning:

To extend anode life, drain water from tank whenever RV is not being used.

Avoid any extended time of non-use with water in tank.
