Which is better magnesium or aluminum anode rod?
However, aluminum rods are the better choice for a water heater that heats up sulfate-tinged water. Sacrificial anodes change sulfates into hydrogen sulfides. When a magnesium anode rod is used, the level of hydrogen sulfide can get too high and cause a rotten-egg stench in your hot water.
What happens if you don't change your anode rod?
Since the lining eventually cracks, tanks have a second line of defense against rust: a long metal “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.
How do you check an anode rod?
Pull the rod out of your water heater and remember to use caution because it's probably very hot. Your anode rod should be around ¾ inch thick. If it's corroded down to less than ½ inch thick or coated with calcium, it needs to be replaced.
Can anode rod causing rotten egg smell?
Many anode rods are made of magnesium or aluminum. When these rods corrode, the metals react with the sulfates in the water, turning the sulfate into stinky hydrogen sulfide.
Should you use Teflon tape on anode rod?
Teflon tape is safe to use on anode rods to establish a watertight seal, some manufacturers even recommend it. It should not interfere significantly with the electrical contact between rod and tank.
What causes an anode rod to go bad?
Anode rods are an essential component of tank-style water heaters. Most anode rods are sacrificial, meaning they are designed to corrode (instead of your water heater lining). Because they are meant to break down, they wear out every few years and need to be replaced.
Is it too late to replace anode rod?
The downside is that if you wait too long to replace the anode rod, it may be too late. If more than five years has passed, it may be too late to save the water heater. Before changing the part, a plumbing professional can drain the water heater to gauge the extent of corrosion inside the tank.
What Does a Water Heater Anode Rod Do?
An anode rod attracts sediment and other corrosive elements that make their way into your water heater. The anode rod sacrifices itself to protect your water heater from corrosion and increases the water heater’s longevity.
How Often Should You Check Your RV Anode Rod?
You should check your RV’s anode rod at least twice a year. Because you should thoroughly flush out your water heater tank before winterizing your RV, this is also a great time to check the anode rod.
