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.
Which anode rod do I need?
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.
Are all water heater anodes the same 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.

Does the length of an anode rod matter?
The length of the anode rod is important in the case of a sacrificial anode. Indeed, as its name suggests, it sacrifices itself to protect your tank from corrosion. As a result, the more magnesium or aluminum there is on the anode, the longer the protection time of your water heater will be.
How do I know if my anode is magnesium or aluminum?
Aluminum and magnesium anode rods are more reactive than water heater metal. Magnesium is more reactive than aluminum. Thus aluminum is good for hard water. Magnesium is good for soft water to keep up with the many corrosive elements.
Are all RV anode rods the same size?

What is the best anode rod for smelly water?
zinc anode rod
Preventative method #1: Use a zinc anode rod
One way to prevent the hydrogen sulfide smell is to use a zinc or aluminum-zinc alloy anode rod. The reason is that zinc doesn’t react the same way with bacteria as magnesium or aluminum (by itself).
Can you cut an anode rod to fit?
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.
Should you use Teflon tape on anode rod?
Teflon tape is safe to use on anode rods to establish a watertight seal, some manufacturers even recommend it. It should not interfere significantly with the electrical contact between rod and tank.
What size socket is anode rod?
4 Use a ratchet wrench and 1 1/16-inch deep socket to unscrew the anode rod from the heater.
What size is Rheem anode rod?
This part is exactly what the Rheem specs call for. The key here is : Anode Rod – 0.900 in. diameter x 44-3/8 in.
What kind of anode rod comes in a Rheem water heater?
Rheem water heaters have an anode rod to protect the metal storage tank unless they are plastic or tankless models. Aluminum and magnesium rods are popular, suitable choices for Rheem heaters, but some better fit specific water conditions. It’s relatively easy to find, detach, and replace the rod.
Which anode rod is in Rheem water heater?
The anode rod in your Rheem water heater is located on top of your tank. More precisely, your magnesium or aluminum sacrificial anode is visible through a hexagonal head located in the center of your tank under a plastic cover.
Does Rheem use aluminum anode rods?
Rheem 0.625 in. Diameter x 42 in. Long Aluminum Anode Rod for Water Heaters AP12938.
Does Walmart carry anode rods?
Camco 11582 42″ Aluminum Anode Rod – Features a 3/4-inch OD Aluminum Anode – Walmart.com.
Are powered anode rods worth it?
Overall, there are quite a few advantages to using powered anode rods. They don’t degrade, prevent smelly water (by killing anaerobic bacteria that leads to that rotten egg smell), and protect your hot water heater from corrosive elements in the water.
