Changing An Anode Rod In A Water Heater Changing An Anode Rod In A Water Heater
Located inside of every water heater is a long bar called an anode rod. This rod has a specific job that adds to the life of your water heater. The anode rod saves you tank from corrosion by being the first to rust. When this happens, the anode rod is no longer any good and must be changed. Replacing the rod every couple of years will double the life of your water heater and save costly replacements.
Turn off Power and Water
Start the process of replacing the anode rod by shutting off the power to the water heater. Then turn off the water valves entering and leaving the water heater.
Drain Water Tank
Near the bottom of the tank is a drain valve. Attach a hose to the valve and drain water from the tank.
Remove Water Heater Anode Rod
At the top of the water heater will be a hexagonal shaped nut. Loosen this with an adjustable wrench. As you loosen the nut, lift out the old rod.
Install New Rod
Wrap plumber's tape to the threads of the new anode rod and place into the water heater. Tighten the nut until it is secure, but not too tight. Turn on the water and power and refill the water tank.
