Before replacing the anode rod in a water heater, ensure all power to the unit is turned off and the water supply is shut off. It's also a good idea to drain some water from the tank to reduce pressure and prevent any spillage during the replacement process.
Yes, it is possible to change a water heater element without draining the entire tank, but there are important precautions to take. Here's how you can do it: Turn Off Power: Ensure the power to the water heater is turned off at the circuit breaker. Turn Off Water Supply: Shut off the cold water supply to the heater.
An important part of your water heater, it moves cold replacement water to the bottom of the tank when you use hot water; otherwise, both will mix and reduce the water temperature. Anode Rod Replacement: While an anode rod costs between $20 and $50, a plumber can replace it for $50 to $150.
Poor water heater performance can sometimes stem from an anode rod that's overdue for replacement. If you notice signs of poor performance, such as discolored or rusty water, sulfuric or rotten egg smells, popping sounds from the tank, or high heating bills, inspect your water rod to determine if it needs replacement.
In other words, it “sacrifices” itself to extend the life of the 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%.
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.
Anode rods are usually installed and kept in the heater for several years, so it may be a bit hard to get loose. You can try using a "breaker bar" for better leverage or you can also try tightening the rod just a little to loosen up the threads.
Your sacrificial anode may last longer, but if it's been more than 5 years since a human being even set eyes on it then you're long overdue for an inspection. 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.
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.
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.
Best Anode Rod for Residential Water Heaters
The choice between aluminum or magnesium anode rods for residential water heaters depends on the local water quality. Magnesium rods are better for areas with soft water, while aluminum rods are ideal for hard water areas.
In general, plumbers cost $45 to $200 per hour, while electricians cost $50 to $100 per hour. Expect the following average price ranges for labor alone: Replacing a tank-style water heater: $150–$450. Replacing a tankless water heater: $600–$1,850.
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.
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.
Installation and Positioning: Anode rods are typically screwed into the top of the water heater tank. Most residential water heaters have one, but larger tanks or those with higher hot water demand may have two. It's crucial for the effectiveness of the rod that it remains fully submerged in water.
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.
Your water heater consists of a number of intricate parts that all must be maintained to ensure your system is working properly and efficiently. Anode rods, screw and bolt elements, drain valves — these are just a sampling of the water heater parts you'll find at Lowe's.
The anode rod attracts corrosive elements, such as oxygen and hydrogen sulfide, which would otherwise corrode the walls of your hot water tank.
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.
To replace the water heater anode rod, you only need to drain about a gallon of water, but this is a good opportunity to flush the water heater tank.
Water Quality Issues: If you notice rust-colored water or sediment particles in your taps, you may have a depleted anode rod and corroded tank. Age of the Water Heater: If your water heater reaches the 10-year mark or beyond, consider replacing the anode rod, even if no apparent signs of corrosion are present.
The tried and true way to remove the “rotten eggs smell” from your hot water tank is to replace your water heater's anode rod with a zinc-aluminum rod. While the aluminum will fight against corrosion, the zinc will combat the reaction that creates the rotten egg smell.
Open the hot water tank drain valve. Let the water run out the garden hose. This can take 20 to 60 minutes, depending on how big the tank is. Be careful not to damage or break the drain valve when you open and close it.
You'll need a socket wrench or breaker bar to take out the anode rod. The usual size is 1-1/16 inches, but it can change based on the heater. If the anode rod is really stuck, an impact wrench can help.
Selecting your new anode rod should be based on your water's condition and your budget. For example, to get rid of bacteria causing your water to smell foul, go with a zinc/aluminum or electric anode rod. For the most economical choice, magnesium is the way to go – but be ready to replace it again in a few short years.
