Replacing a water heater anode rod is an important maintenance task that can help extend the lifespan of your water heater. In recent years, powered anode rods have become a popular alternative to traditional sacrificial anode rods. Powered anode rods use electricity to generate a protective field that prevents corrosion, making them a potentially more effective and long-lasting option. If you’re interested in replacing your water heater’s anode rod with a powered anode rod, here’s what you need to know:
Gather Your Materials and Tools
To replace your water heater’s anode rod with a powered anode rod, you will need the following materials and tools:
- Powered anode rod
- Teflon tape
- Anode rod socket wrench
- Flathead screwdriver
- Wire stripper/crimper (if not included with the powered anode rod)
Turn Off the Power and Water Supply
Before you begin replacing your water heater’s anode rod, turn off the power to the water heater at the circuit breaker and shut off the water supply to the tank.
Drain the Water Heater
To replace the anode rod, you will need to drain the water heater. Connect a hose to the drain valve at the bottom of the tank and open the valve to allow the water to drain out.
Remove the Old Anode Rod
Once the tank is drained, use an anode rod socket wrench to remove the old anode rod from the top of the tank. If the rod is difficult to remove, you may need to use a breaker bar to provide additional leverage. Use a flathead screwdriver to remove any insulation or debris from the opening.
Install the Powered Anode Rod
Follow the manufacturer’s instructions to install the powered anode rod in the opening at the top of the tank. Be sure to use Teflon tape to seal the threads and prevent leaks.
Connect the Wiring
If your powered anode rod comes with wiring, you will need to connect it to a power source. Follow the manufacturer’s instructions to strip and crimp the wires and connect them to the appropriate terminals. Be sure to connect the ground wire to a grounding screw on the tank.
Refill the Water Heater
Once the wiring is connected, close the drain valve and open the water supply valve to refill the tank. Allow the tank to fill completely before turning the power back on.
Test the Water Heater
Once the tank is full and the power is restored, test the water heater to ensure that it is functioning properly. Check for leaks and monitor the water temperature to ensure that it is heating properly.
Replacing your water heater’s anode rod with a powered anode rod can be a more effective and long-lasting option for protecting your tank from corrosion. Be sure to follow the manufacturer’s instructions carefully and consult with a professional plumber if you have any questions or concerns.
