Types of Water Heater Anode Rods

 
 
01
 

Magnesium

Anode rods made out of magnesium are the most common type found in homes. magnesium corrodes faster than other materials, so magnesium rods are not ideal for homes that have hard water.

 
02
 

Aluminum

This type of anode rod is known for its affordability and flexibility. These rods also last longer compared to their magnesium and zinc counterparts. Due to the durability of aluminum rods, they are better suited to homes with hard water.

 
03
 

Zinc

Despite their name, zinc anode rods are not entirely composed of zinc. Instead, they are made with a combination of zinc and aluminum. The top benefit of zinc rods is that they are designed to resist odor-causing bacteria, which keeps unpleasant smells at bay in your home.

Inspecting Anode Rods
 

Safety First: Before beginning any inspection, ensure your safety. Turn off the power to the electric water heater at the circuit breaker or turn off the gas valve if it's a gas water heater. Allow the water in the tank to cool down.

 

Locate the Anode Rod: The anode rod is usually located at the top of the water heater. It may be directly visible or hidden under a cap or insulation. Consult your water heater's manual for the exact location.

 

Drain Some Water: To access the anode rod, you may need to drain a few gallons of water from the tank. Connect a hose to the drain valve at the bottom of the tank and let out enough water to lower the level below the anode rod's position.

 

Remove the Anode Rod: Use a socket wrench to loosen and remove the anode rod. It's typically secured tightly, so some force may be required.

 

Examine the Rod: Check the rod for any signs of excessive wear. A healthy anode rod will have some minor pitting and wear, but if it's heavily corroded, reduced significantly in size, or covered in a thick layer of calcium, it needs to be replaced.

 

Measure the Rod: Use a tape measure to check the remaining thickness of the rod. If it's less than ½ inch thick, it's time for a new one.

 

Reinstall or Replace: If the anode rod is still in good condition, carefully replace it and tighten securely. If replacement is necessary, make sure to choose the correct type and size for your water heater.

 

Refill the Tank: After reinstallation, refill the tank before turning the power back on to avoid damage to the heating elements in electric heaters.

 

Anode rod is a manufacturing material
 
 

Magnesium

Magnesium is the best-performing metal for anode rod construction, but it's the least durable. It generates around 1.6 volts in the cylinder but may need to be replaced every year if your water is particularly hard or soft.

 
 
 

Aluminium

Aluminium generates 1.1 volts and is the middle ground when it comes to anode construction. You'll need to inspect it annually, but usually, they will only need to be replaced every five years or so.

 
 
 

Zinc

This is the lowest performance material, generating just 1.05 volts. It has a lifespan pretty comparable with aluminium.

FAQ

 

Q: How often should an anode rod be changed?

A: The frequency of anode rod replacement depends on several factors, such as water quality, usage patterns, and the type of anode rod installed. In most cases, we recommend inspecting and potentially replacing the anode rod every 3 to 5 years.

Q: What happens if you don't replace anode rod?

A: Anode rods require routine inspection and replacement, approximately every three to five years. Without proper maintenance, the anode rod loses its ability to divert damaging particulates from your tank and can accelerate rust and corrosion from chemical reactions, excessive heat, and imbalanced pH levels.

Q: Can you run a hot water heater without an anode rod?

A: Without a functioning anode rod, the tank itself would start to corrode, leading to leaks and system failure.

Q: What causes anode rod to fail?

A: The quality of your water supply is another consideration; harder water typically causes faster deterioration of anode rods. Furthermore, some anode rods can interfere with the function of water softeners, so compatibility is essential if you use such a system.

Q: How much does it cost to replace the anode rod in a water heater?

A: 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.

Q: Do you have to drain water heater to replace anode rod?

A: 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.

Q: What to do if anode rod is stuck?

A: Lubricate with Care. For an extra edge, use a food-grade penetrating liquid. This type of lubricant is safe for use around water systems and can help loosen the anode rod without risking the contamination of your water supply.

Q: Do all water heaters use the same anode rod?

A: All sacrificial anode rods are not the same. And, generally speaking, they are not specific to the water heater. Rods can differ in length, diameter, and composition.

Q: How are anode rods attached to the water heater tank?

A: There are two ways that the rod may be attached – by nipple type of plug type. Nipple type is found on the hot water outlet, while the plug type is on top of the tank in a separate opening.

Q: Can you have more than one anode rod for extra protection?

A: Yes! You can buy a longer warranty, which means the anode rod is going to be longer. And you can add a shorter rod as a secondary preventative measure. When purchasing a new water heater, we highly recommend buying the longest warranty available to ensure you're covered for longer.
