How do I know what size anode rod to buy?
As a rule you want the anode to be “tip to toe” running the full height or length of the tank. If you cant see your brand on the chart then just measure the length of the tank and pick the closest length of anode. If the anode is too long they can be simply cut to length with a hack saw.
How do I choose an anode rod for my water heater?
Aluminum anode rods are best for places with hard water. The aluminum rod will withstand harder water better than a magnesium or zinc rod. Zinc anode rods are designed to eliminate or reduce the sulphur or rotten egg smell present. A Zinc anode rod made from a combination of aluminum and zinc.
Are water heater anode rods universal?
In most cases, water heater anode rods are universal. The only exceptions are: Buderus: They use another type of threading to install the magnesium anode. Bradford White: Some model have the anode is built into the hot water outlet.
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.
Which is better aluminum or magnesium anode rod?
For harder water an aluminum anode rod is the best choice for your heater and if you live in an area with soft water then a magnesium anode rod is your best choice. Aluminum anodes tend to be cheaper than magnesium anode rods. A magnesium rod will generally last less than an aluminum rod.
How do I know if my anode rod 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.
Are aluminum anodes better than zinc?
Driving voltage: Aluminium anodes has a relatively high driving voltage. This means that it provides better distribution of the current, compared with zinc. Environment: Aluminium anodes carry a better environmental footprint than zinc anodes.
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. Softening can make smelly water much worse.
Is it OK to remove anode rod?
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.

Are powered anode rods worth it?
As mentioned, powered anode rods are well worth the cost, but may not be ideal in every situation. Additionally, you may not wish to replace a rod which is still good just to gain the benefits of a powered one.
Can I replace anode rod myself?
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.
