When to replace an anode rod on a water heater?
The anode rod protects the tank of electric water heaters & signs it should be replaced are a rotten egg smell, no heat & strange sounds. In the electric water heater tank type units, the anode rod plays a key role.
What happens when an anode rod goes bad?
A bad anode rod can cause discolored water, a rotten egg smell, air in the lines and intermittent hot water. The anode rod protects the tank of electric water heaters & signs it should be replaced are a rotten egg smell, no heat & strange sounds.
How often should an anode rod be inspected?
Annual tune-ups are recommended. You should also have the rod inspected, by a professional, every three years. Anode rods are located in an awkward spot, usually right under components like the water inlet valve. Removing a rod in a safe manner demands specialized tools only we have access to.
Why does my water heater anode rod smell Rotten?
Certain water conditions will cause a reaction with magnesium or aluminum anode rods to produce a “rotten egg” smell. By replacing the magnesium or aluminum anode rod with a combination aluminum/zinc/tin anode rod you may help decrease this smell, but it may not eliminate it completely. How Do I Choose the Right Replacement Anode Rod?
How long does an anode rod last on a water heater?
The anode rod is “self-sacrificing” and will continue to corrode until eventually it must be replaced. When there’s no sacrificial metal left on the anode, the tank can rust out. Anode rods generally last about five years but it really depends mostly on the quality of your water and how much water travels through your water heater.
Can a water softener cause anode rods to corrode?
When sodium is added to the water (such as when a water softener is used), anode rods can corrode more quickly. Water softeners can help reduce scale build-up and sediment, but anodes can corrode in as little as six months if the water is over-softened.
What does sacrificial anode rod on water heater do?
A water heater sacrificial anode rod is a metal rod and is generally screwed into the top of the tank. It’s job is to attract corrosive elements in your potable water. Over time the rods get “sacrificed” for the healthy survival of the heater’s tank and the result can lead to smelly water.
Can a powered anode be used in a sacrificial tank?
Because of the long lifespan, you can use a powered anode rod to preserve a tank well past its warranty, without any signs of corrosion to the lining or anode itself. They tend to be quite a bit more expensive than sacrificial rods, so they may not be the best choice for every home.
If your hot water begins to smell bad, replace the anode rod with a less reactive zinc-aluminum rod to help combat the smell. Use these steps to replace the anode rod in Kenmore, State, A. O.

Why does my water heater anode rod smell bad?
Natural micro-organisms and sulfates that exist in some water can react to the aluminum or magnesium anode rods in the hot water tank, creating a rotten egg smell. If your hot water begins to smell bad, replace the anode rod with a less reactive zinc-aluminum rod to help combat the smell.
Which is the best material to replace an anode rod?
There are several options for replacing your anode rod, with magnesium, aluminum, or a combination of aluminum, zinc and tin being the most common anode rod materials.
What is a water heater anode rod and when should I replace it?
An anode rod is a sacrificial steel core wire that is wrapped with aluminum, magnesium, or zinc. Anode rods work by attracting corrosive particles found inside your water heater tank to protect the tank liner and reduce the risk of explosion. Anode rods should be replaced every 3 to 5 years depending on your water quality.
Why do water heaters need an anode?
Powered anodes are also recommended when odor-causing bacteria infect a water heater tank and send noxious fumes running up water pipes, although special sacrificial anodes made from zinc and aluminum are also effective at counteracting this particular problem.
When is it time to change the anode rod in your water heater?
In most cases, you will need to change your water heater anode rod approximately once every 6 years so long as it operates under normal working conditions. However, depending on the composition of your water, you may need to change the anode rod more frequently.
Why do you need an anode rod in your RV water heater?
An anode rod is a solid metal cylinder that gets screwed into a water heater’s drain plug to prevent the steel water heater tank from rusting inside . They are made from aluminum, magnesium, or zinc, all metals that will “sacrifice” themselves through electrolysis and save the exposed steel water heater tank from a similar fate.
How do you change the rod on a water heater?
This Old House plumbing and heating contractor Richard Trethewey shows a simple way to add years to your water heater, by swapping out the sacrificial metal rod that prevents rust inside the tank. (See below for a shopping list and tools.)
What can I use to remove an anode rod?
The anode rod can be removed with a boxed end wrench or socket. If it will not turn using a wrench, use a socket and breaker bar. Tightening the anode rod slightly will help break the threads loose, making removal easier.
