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.
What happens if you don’t replace anode rod?
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, eventually causing it to burst.
How long will a water heater last without an anode rod?
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.
When should anode rods be replaced?
Check The Anode Rod Once a Year & Replace It Every 5 Years 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.
How long does it take for an anode rod to go bad?
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 often should you change anode rod in 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%. This is especially true if you have hard water or use a water softener.
How much does it cost to replace a water heater anode rod?
An anode rod costs about $50. Some homeowners may feel comfortable replacing it themselves. If not, call a professional plumber, who can assist. The cost of having it replaced professionally may be around $250 or $300.
What are the signs your hot water heater is going out?
Delivering Rusty or Cloudy Water Rust deposits or a metallic odor coming out with hot water can signal either rusty pipes or rust inside the water heater. If corrosion is eating away the metal from the inside, leaks are inevitable. Murky water from the tap can also be signs that the water heater will fail soon.
How do you check the anode rod on a water heater?
Open the spigot and drain a little water to relieve some pressure and heat inside the tank before opening the top for the anode rod. Next, go to the top of your water heater and look for a hex head bolt. If you don’t see the hex head, it’s likely built into your water heater system.
Do hot water heaters come with anode rods?
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. Tankless water heaters don’t have anode rods, but all standard tank-style water heaters do.
Can anode rod causing rotten egg smell?
The most common cause of smelly water is anaerobic bacteria that exist in some water and react with the magnesium and aluminum sacrificial anodes that come with most water heaters to produce hydrogen sulfide gas, making the classic rotten egg odor.
Can I use impact driver to remove anode rod?
To loosen the rod, you’ll need an air compressor, a 1/2-in. -drive impact wrench and a 1-1/16-in. If you don’t have an impact wrench, go buy a cheap one for about $30. Even with a breaker bar, it can be nearly impossible to break the anode rod free.
How often should you flush a water heater?
Tip: To maintain the upkeep of your water heater, flush your water heater every six months or so. If you have harder water, or water that contains more minerals, you may want to flush it more often.
How do you know if anode rod is magnesium or aluminum?
A magnesium rod will generally last less than an aluminum rod. One issue with aluminium rods is that the corrosive material that is formed on the anode tends to harden and sink to the bottom of the water tank.
Why does my hot water smell like rotten eggs?
The most common odor problem from water heaters is a rotten egg smell that comes out of your faucets and fixtures when running water. This smell is typically caused by sulfate bacteria that can develop within the tank. The soft water breaks down the magnesium and creates sulfate gas within the water heater.
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. However, the length and type of the anode rod may not be the same.
How do you clean an anode rod?
You cannot clean your anode rod in your water heater . However, it is important to inspect the sacrificial anode rod every 1 to 3 years and replace it after more than 50% of its wear and tear to avoid corrosion of your tank.
