If your water heater doesn’t have a separate hole for your anode rod, it is most likely attached to the hot water outlet. Unscrew the flex supply to the hot water outlet, which should enable you to unscrew the anode rod and pull it out to check.
Can you run a water heater without an anode rod?
Without a working anode rod, your water heater tank will be vulnerable to rust, corrosion, and other damaging effects of chemicals and minerals in your water supply.
Where is the anode rod in a water heater?
The anode rod will be located on the top side of the unit. In some cases, it may be directly connected to the hot water outlet line on top of the heater.
Is anode rod necessary?
Yes, an anode rod is necessary. It protects your water heater from corrosion and extends its life. However, once the magnesium or aluminum from your anode is dissolved, the steel walls of your water heater will start to rust.
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. The diameter of residential water heater anode rods is universal at 3/4 inches.
How long will water heater last without 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.
Do stainless steel water heaters have anode rods?
Unlike glass lined water tanks, stainless steel tanks do not need a “sacrificial anode” in order to prevent corrosion on its surface. This means there is no need for inspection or replacement of anodes, saving time and cost in maintenance over the life of the water heater.
Do Bradford White water heaters have anode rods?

How do I know which anode rod to buy?
Magnesium anode rods are expected to work better in a home with soft water. Aluminum anodes are appropriate for homes with hard water and a high PH. Zinc anodes work best if a home is starting to smell like rotten eggs and is best for replacing water heaters that already dissolved.
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 you check a water heater anode?
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.
How often replace anode rod in water heater?
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. Very large families, for example, may use a lot more hot water, and may need more frequent anode rod replacement intervals.
Are all anode rods the same thread size?
All anode rods are made to fit in a ¾” NPT socket. Some replacement rods might only come in one length, but if it’s too long, you can cut some off. You won’t hurt it a bit. If you are working on a newer water heater or one that’s 20 years old, the procedure is no different.
Are anode rods standard size?
An anode rod measures up to 40 inches long, depending on the size of your appliance. Sacrificial anode rods should be replaced on a routine basis.
