How often should you change anode rod in water heater?

Most water heater manufacturers will recommend inspecting the condition of the sacrificial anode every one (1) to three (3) years and replacing it when it has been consumed more than 50%. This is especially true if you have hard water or use a water softener.

Should I replace the anode rod in my water heater?

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 water heater anode rod before it fails, about every five years, you can double the life of your water heater.

When do I need to replace the anode rod on my water heater?

Go you for researching how to replace your water heater anode rod! Maintenance on a water heater is one of those items that, in all honesty, generally doesn’t make the to do list. We all expect to have hot water in our houses and then one day a leak occurs or some other dire circumstances requiring a new water heater.

Why does my water heater have a sacrificial anode?

Water heaters are designed to corrode this piece of metal extending down through the tank. Rather than corrosion building up on the outside of the steel tank it attacks the anode rod instead. Hence, the label “sacrificial”. If the sacrificial anode rod is not replaced the water eats all the way through it and then starts corroding the tank.

Which is the best anode for a water heater?

The zinc anode works better where the water heater smells like rotten eggs. These all anodes work better in removing smell from water tanks. The anodes are in the wrong way into the tank’s highest point and stretch out almost the whole way to the base.

How often should you replace the sacrificial anode rod?

The even bigger maintenance item is replacing the sacrificial anode from every three to five years. Changing out this one rod extends the life of your water heater to almost double the average lifespan. $30-$50 and a little elbow grease to keep yourself from buying an extra $700-$900 tank water heater?!?!

Where to buy anode rod?

Aluminum anode rods are a common type used in new water heaters. There are both health and performance concerns associated with aluminum anode rods. You can purchase an aluminum anode rod online, at plumbing and home supply stores for around $20 to $25.

Do powered anode rods work?

Powered anode rods are non-sacrificial rods (meaning they don’t degrade like a normal anode rod) which use electrical pulses to deal with corrosive elements in your water. These pulses scatter the harmful electrons, preventing them from accumulating along the lining of your tank. Overall, there are quite a few advantages to using powered anode rods.
