As a general rule, anode rods need to be replaced about every 4-5 years. However, this can vary depending on how much water flows through your gas water heater or electric water heater. Very large families, for example, may use a lot more hot water, and may need more frequent anode rod replacement intervals.

What happens if you don’t change your anode rod?

If the rod doesn’t get replaced by the time it’s reached the end of its lifespan, the water in your tank will immediately try to corrode the tank walls. If you don’t keep up with maintenance, you may not realize this has happened until the tank rusts through and leaks on the floor.

Is it worth it to change anode rod?

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.

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.

How often should you replace anode rod?

about three to five years

When there’s no sacrificial metal left on the anode rod, your water heater tank can rust out, eventually causing it to burst. Anode rods generally can last about three to five years but it really depends mostly on the quality of your water and how much water travels through your water heater.

How long will water heater last without anode rod?

8-12 years

Diminished Water Heater Lifespan: Without a sacrificial anode rod replacement, the average tank water heater will last a maximum of 8-12 years. However, your water heater may start failing as early as 5 years old without this essential care.

How do I know if my water heater anode is 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 you flush a water heater?

Anode rods generally can last about three to five years but it really depends mostly on the quality of your water and how much water travels through your water heater.

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.

Can you cut down an anode rod?

Yes, you can cut your sacrificial anode rod, whether it is magnesium or aluminum, to replace it. To do this, use a pair of gloves and a saw and cut as you remove the old anode.

Why is my hot water black and smelly?

The incidence of rotten egg odor or black water in hot water lines is due to the reaction of sulfates and micro-organisms in the water that create Hydrogen Sulfide (H2S). This is a water chemistry condition, rather than a water heater problem.

Are anode rods universal?

Anode rods are not universal. Anode rods vary in length and material. Some anode rods are installed at the top of the water heater tank, while others are attached to the hot water outlet. The diameter of residential water heater anode rods is universal at 3/4 inches.

Should I use aluminum or magnesium anode rod?

Aluminum anode rods may not have the high-level corrosive properties to keep up with the needs of your water heater, leading to faster corrosion and deterioration of the tank. Magnesium anode rods protect against corrosion better, extending the life of your hot water tank.
