Where Is the Anode Rod on a Ruud Water Heater?
Maintaining your hot water heater is one of the most effective ways to extend its lifespan and prevent costly repairs. The anode rod, a small piece of metal, plays a significant role in protecting the tank from corrosion.
In this guide, we will explain where the anode rod is on a Ruud water heater, how to check and replace it, and why upgrading to a powered anode rod from Corro-Protec can save you time, money, and hassle.
Where Is the Anode Rod on a Ruud Water Heater?
On most Ruud water heater models, the anode rod is located at the top of the tank. When you are facing the front of the unit, it is usually found under a small plastic cover on the right side.
Some Ruud heaters may have more than one anode rod, or the rod may be combined with the hot water outlet. Checking your owner’s manual is always a good idea, but in most cases you will find the rod in the top-right location.
How to Inspect and Replace the Anode Rod
Inspecting the anode rod every one to two years is recommended. Here are the basic steps for checking or replacing the rod in a Ruud water heater:
Step 1
Shut off the cold water inlet.
Step 2
Release the pressure from the tank.
Step 3
Locate the anode and Inspect it: If it’s heavily corroded, rusted, or reduced to a thin core wire, it needs to be replaced.
Step 4
Remove the plastic cover and use an impact wrench or ratchet bar to loosen the hexagon-shaped head of the anode rod.
If you choose to install a powered anode, the process is similar but requires connecting the power supply. Corro-Protec offers a clear step-by-step installation guide to make this process easier.

Why Choose a Powered Anode Rod for Your Ruud Heater?
A powered anode rod offers several advantages for Ruud water heater owners:
- Extended Tank Life: The powered system protects all areas of the tank, including weld seams and weak spots.
- No Rotten-Egg Smell: If your hot water has ever smelled like sulfur, a powered anode can stop that reaction.
- Low Maintenance: Once installed, there is no need for regular replacement.
- Universal Fit: Corro-Protec rods are designed to fit a wide range of water heater brands, including Ruud.
- Energy Efficient: The system uses only a small amount of electricity each year.
By upgrading, you reduce the risk of leaks, odors, and premature tank failure.
