How to Cut an Anode Rod?
If you have an anode rod that doesn’t fit your water heater perfectly, you can cut it down. The correct way to do this is to place it into the water heater (without screwing it in), so you can see how high it is. Then, measure the distance that the rod protrudes out of the top of the tank and add an extra inch. Use a hacksaw to cut the excess off and then place the rod back in the tank. Screw it into place, and you’re done!
How Often Should You Change Anode Rods in Water Heaters?
Water heater anode rods should be changed approximately once every 3 to 5 years, provided that the unit is functioning correctly.

What is an anode rod and how does it work?
A water heater anode rod, also known as the sacrificial anode, is the element that protects the metal tank from corrosion when in contact with the water (electrolyte).
How long does a water heater anode last?
The longevity of the water heater anode rod depends on several factors, and under normal conditions, you can expect it to last 3-5 years. If you prefer, you can buy a water heater, such as Rheem Marathon, which does not use the anode since the tank is made of plastic.
Why is an anode rod important?
The water heater tank is usually constructed of steel, and the inside metal tank surface, as it is exposed to the aggressive water action, has a glass lining bonded to the steel for protection. As the lining could have or is subject to cracks, either due to the thermal and mechanical stress or imperfect manufacturing process, water can still get in touch with the metal tank, causing corrosion. This is why an anode rod is an important and integrated part of every design.
What is an anode in a water heater?
The anode is made of steel core wire that is covered with one of three materials; aluminum, zinc, or magnesium. As the anode has a higher current potential than other metal surfaces in the water heater, the galvanic current will flow from the rod to other metal parts, preventing corrosion.
What type of anode is used for water?
The magnesium anode has the weld bead on the plug. This type is the most used, especially where water is soft. It provides excellent protection, but it doesn't last long.
How to fix stubborn anodes?

What Is An Anode Rod and How Does It Work?
An anode rod is a steel wire surrounded by either zinc, aluminum, or magnesium. It is usually about 4 feet long. It is screwed into the top of a water heater and protects the water tank from the formation of rust. It does this through a process called electrolysis. The anode rod is designed to be submerged in water to attract rust and contaminants. Since this component attracts impurities in the water, it will prevent and stop deterioration on the inner steel walls of the water tank. This self-sacrificial process of the metal rod ensures the water heater’s longevity since it won’t rust.
What does it mean when an anode rod is corroded?
However, if the rod is deteriorating and corroding, it means that it’s doing its job, which is why this is the most common problem. If the steel wire of the rod’s core is exposed, then it might be time for a new one. Anode rod corrosion starts at the top or bottom of the rod and continues on to the core. If there is more than 6 inches of deterioration, it is time to replace it.
How long do anode rods last?
