Where Is the Anode Rod on a GE Water Heater?
GE Water Heater Anode Rod Location
In most GE hot water heaters, the anode rod is located on the top of the tank. Depending on the model, it may be directly under a hexagonal plug or built into the hot-water outlet connection.
- Standard GE electric and gas water heaters: Look for the rod near the hot-water outlet.
- GE hybrid water heaters: The rod is usually recessed on top of the tank.
- GE GeoSpring water heaters: The rod is often under a removable cover plate.
Knowing the exact location makes it easier to inspect or replace when needed.
How to Replace an Anode Rod in a GE Water Heater
Replacing a GE water heater anode rod is manageable with the right tools and a few simple steps.
Step-by-Step Instructions
The following steps apply when the GE water heater model has the anode in the dedicated anode port, which is the case for the majority of them. If your water heater has the anode in the hot water outlet, follow the installation guide for the hot water outlet instead.
Step 1
Turn off the power or gas, and water supply.
Step 2
Relieve pressure and drain water.
Step 3
Locate and remove the old rod.
Step 5
Install the new rod.
Step 6
Restore service.
For more detailed instructions and the necessary tools, refer to our Regular Model Installation Guide or your user manual.
Comparing Replacement Options
Traditional anode rods are made from magnesium or aluminum, but they both have limitations. A powered anode rod is a modern alternative that eliminates many of those issues.

Why Powered Anode Rods Are the Right Choice
While aluminum and magnesium rods can temporarily protect a GE water heater, they often lead to odor problems and require frequent replacements. A powered anode rod provides a permanent solution to the issues usually associated with traditional rods.
The advantages include:
- Eliminates sulfur and rotten egg smells.
- Protects tanks in all types of water, including well and softened water.
- Reduces maintenance and replacement costs over time.
- Backed by a 20-year limited warranty when registered.
For GE water heaters, including GeoSpring and hybrid models, a powered anode rod offers the best long-term value and reliability.

Summary
- Most GE anode rods are located on the top of the tank, often under a hex head plug or near the hot-water outlet.
- The anode rod in a GE water heater protects the tank from rust and corrosion.
Over time, the rod deteriorates and must be replaced to keep the tank protected.
- Traditional aluminum and magnesium rods need regular replacement and may cause odor issues. A powered anode rod offers long-term protection, eliminates rotten egg smells, and is maintenance-free.
FAQ
Traditional aluminum or magnesium anode rods typically need to be replaced every 1 to 5 years, depending on water quality and usage. However, if you notice rust-colored water, leaks, or a rotten egg odor, it may need replacement sooner. With a powered anode rod like Corro-Protec, there’s no need for replacement, and it eliminates the rotten egg smell from your hot water.
In most GE water heaters, the anode rod is located on top of the tank, often under a hex head plug or integrated into the hot-water outlet connection.
