By replacing your anode rod every 3-5 years, your water heater can last well over 20 years without any risk of leaks and resulting water damage.
In most cases, we recommend inspecting and potentially replacing the anode rod every 3 to 5 years. However, certain water conditions may accelerate the corrosion process, requiring more frequent replacements.
That's because, in some cases in particularly mineral-rich water, the anode rod will last less than a single year – although 3-5 years of life is about average.
Visual inspection. Check your water heater and water anode rod for corrosion and rust at least once per year. If the rod appears heavily worn and degraded to its core wire, it's ready for replacement.
The rods can deteriorate in as little as 3 to 5 years, depending on many factors, including the hardness or softness of the water. Without a working anode rod, the water heater tank will be vulnerable to rust, corrosion, and other damaging effects of chemicals and minerals in the water supply.
They protect the tank by attracting corrosive elements, ensuring the integrity of the water heater's interior. Even in areas with soft water, the presence of oxygen and other natural elements can lead to corrosion, making the anode rod indispensable.
You'll spend between $20 and $50 on the rod. If you choose to hire a water heater pro to get the job done, an anode rod replacement will cost you between $200 and $300. If you're not sure whether to handle this repair yourself, first examine your water heater.
Note: If your anode rod is on the top of the heater, you will only need to allow the tank to drain about a quart or 1/2 a gallon of water. If the anode is located on the side, drain the tank until the water is below the anode rod port.
Most homeowners should flush their water heaters every 6 months or so, but if you have extremely hard water, you may want to do it more often. Flushing your hot water heater could be necessary as often as every few months depending on the mineral content of your local water supply.
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.
How Often Should You Replace an Anode Rod? The longevity of an anode rod depends on water quality, usage, and the material. But generally, an anode rod replacement must be done every three to five years. Check your water heater regularly to determine whether or not your anode rod needs to be replaced.
In summary, the main difference between magnesium and aluminum anode rods is that magnesium anode rods are more efficient in soft water and have a shorter lifespan, while aluminum anode rods are more efficient in hard water and have a longer lifespan.
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.
In any case, water heater anode rods are essential for protecting your tank from corrosion, but they eventually wear out after around 3-5 years, depending on many factors including the hardness or softness of your water.
The frequency of anode rod replacement can vary based on factors like water quality, the volume of water usage and the type of rod used. However, most professionals recommend inspecting the anode rod every one to three years and replacing it every four to five years.
The composition of aluminum anode rods for water heaters ensures they last longer and are more resistant to the harsh conditions inside the tank.
If neither you nor a professional have flushed your water within the last five years, Water Heaters Now recommends not flushing it yourself.
-Reduced Efficiency: As scaling collects at the bottom of the tank, your water heater will become less effective at heating the water in the tank. -Corrosion: If your water heater goes long enough without a proper flush, you could also have corrosion attacking the tank itself, weakening its structural integrity.
It is recommended that you flush your water heater at least once per year. Doing so will help to prevent the potential problems that sediment can bring over time. Typically, it takes one to two hours to flush a water heater. The size of your tank will impact the amount of time it takes to drain.
If you suspect your water heater is more than 10 years old—it is time to consider replacing it before you're left with an emergency decision. To determine the age of your water heater, you'll need to identify the Brand Name and Serial Number for your unit.
The residential models have anode rods to extend the life of the tank portion of the heater. They also have other features that make servicing and maintaining the equipment easy, including low-restrictive brass drain valves. The unit can even be laid down, making transport easier on the machine and the technician.
Anode Rod Replacement: While an anode rod costs between $20 and $50, a plumber can replace it for $50 to $150. The job typically takes about an hour. The anode rod protects the tank from corrosive materials and needs to be changed every few years. Water Heater Tank Flush: A water heater flush kit can cost around $150.
For example, the average 40-gallon water heater installation cost runs between $1,000 and $2,500, while its 80-gallon counterpart runs between $2,650 and $3,910.
While today's water heaters are better designed than older models, they still require regular maintenance in order to prolong their lives. With regular inspection, draining, and flushing, you can expect a gas water heater to last anywhere from 8-12 years and an electric water heater to last anywhere from 10-15 years.
Anode rods are consumable maintenance parts and are excluded from warranty coverage. 3.
