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. If you have the user manual for the water heater, it will include a diagram which shows where the anode rod is located, otherwise consult the manufacturer’s website.
How long is the anode rod in a Rheem water heater?
Rheem AP12938 Anode Rod, 0.625-Inch Diameter by 42-Inch long, Aluminum.
How often should you replace anode rod in hot water heater?
By replacing your anode rod every 3-5 years, your water heater can last well over 20 years without any risk of leaks and resulting water damage.
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.
What kind of anode rod comes in a Rheem water heater?
The Rheem SP11526C is a magnesium anode rod.
Do all hot water heaters have anode rods?
Most anode rods are sacrificial, meaning they are designed to corrode (instead of your water heater lining). Because they are meant to break down, they wear out every few years and need to be replaced. Tankless water heaters don’t have anode rods, but all standard tank-style water heaters do.
Does my water heater have an anode rod?
In most cases, the hexagonal head of the rod is visible on the top of the water heater. If you don’t see the hex head, check your owner’s manual. The rod may be under the water heater’s sheet metal top or connected to the hot water outlet nipple. (A few newer plastic-lined tanks have no anode rods to replace.)
Should you use Teflon tape on anode rod?
Yes, teflon tape may reduce the effectiveness of the anode rode by electrically insulating the rod from the water heater chassis. The chances of it completely isolating it are nearly impossible though. Use pipe joint compound if you have it, and use teflon tape if you don’t.
Do all Rheem water heaters have anode rods?
All water heaters have one Anode Rod. This rod starts to attract the corrosion (caused by the water) which minimizes the tank corrosion after the glass liner fails. Rheem Professional Grade has one Anode Rod with an optional port for a second rod. The Anode Rod is made of magnesium which corrodes easier than steel.
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 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 much does it cost to replace an 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 magnesium or aluminum anode rod?
Aluminum anode rods may not have the high-level corrosive properties to keep up with the needs of your water heater, leading to faster corrosion and deterioration of the tank. Magnesium anode rods protect against corrosion better, extending the life of your hot water tank.
Do aluminum water heaters need anode rods?
If you have a Suburban water heater, the tank is porcelain-lined steel and requires an anode rod to prevent corrosion of the steel tank. If you have an Atwood water heater, your water heater tank is aluminum and does not require one.
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.
Is it too late to replace anode rod?
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. Before changing the part, a plumbing professional can drain the water heater to gauge the extent of corrosion inside the tank.
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.
