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 do you know when to replace an anode rod in a 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 do you test a water heater anode rod?
- Turn Off Water and Fuel Supply (Gas or Electric) Locate the gas line near the bottom of your water heater.
- Drain Some Water.
- Locate Anode Rod.
- Loosen the Hex Head and Remove the Anode Rod.
- Install New Sacrificial Anode Rod.
- Turn Off Water and Fuel Supply (Gas or Electric)
- Drain Some Water.
- Locate Anode Rod.
How often should water heater anodes be replaced?
about every five years
When the rod itself becomes so corroded that it can no longer do its job, the tank soon rusts out, leaks and needs replacement. However, if you replace your water heater anode rod before it fails, about every five years, you can double the life of your water heater.
What happens if you don’t change your anode rod?
The rods can deteriorate in as short a period as 3 to 5 years, depending on many factors that include the hardness or softness of your drinking 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.
Do all hot water heaters have anode rods?
Anode rods are an essential component of tank-style water heaters. Most anode rods are sacrificial, meaning they are designed to corrode (instead of your water heater lining).Tankless water heaters don’t have anode rods, but all standard tank-style water heaters do.
How much does it cost to replace 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.
Is it too late to replace anode rod?
Anode rods are relatively cheap, usually costing between $30 and $40, and a plumbing pro can install them safely and quickly.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.
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.
What size socket do you need to remove an anode rod?
4 Use a ratchet wrench and 1 1/16-inch deep socket to unscrew the anode rod from the heater.
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.
What causes hot water heater to corrode?
There are different types of corrosion, but when we’re talking about a residential water heater, it’s the corrosion that occurs because of the mix of oxygen and water in contact with metal. A water heater is designed to resist corrosion through a number of methods.
Can anode rods be cut?
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.In confined spaces, cutting the anode rod technique is often used.
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.

How do I know if my 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.
Can I replace anode rod myself?
How to Remove a Water Heater Anode Rod. Water heater anode replacement can be completed by homeowners. If you’d like to inspect or replace your water heater’s anode, follow these steps: For electric water heaters: Turn off the water heater and cut power to the unit from the circuit breaker.
Why do I need to keep resetting my water heater?
When your thermostat stops working correctly, it can fail to regulate the temperature in your electric water heater properly. This, in turn, will cause your water to heat up to dangerous levels, which will cause the reset switch to trip.
Do anode rods work?
As long as the anode rod is degrading in the tank, the tank lining will be protected from rusting. This is accomplished through a process called electrolysis, by which the metals in the anode rod attract ions that normally cause rust in iron and steel.
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.
What is Mg anode?
What Does Magnesium Anode Mean? A magnesium anode is used as a sacrificial anode in cathodic protection. Magnesium has the highest driving voltage of all the materials used for sacrificial anodes. Magnesium is low on the noble scale, and therefore corrodes easily.
