Anode Inspection and Replacement
Water heater components and stored water may be HOT when performing the following
steps in this procedure. Take necessary precaution to prevent personal injury.
Step 1.
Move the gas control power switch to the "OFF" position
Step 2.
Unplug the water heater from the wall outlet.
Step 3.
Turn off the cold water supply to the water heater. Connect a hose to the
drain valve of the water heater and route to an open drain. Open a nearby hot water
faucet to vent the water heater for draining. Open the drain valve of water heater and
allow the water heater to drain to a point below the outlet connection nipple.
Step 4.
Disconnect the outlet nipple from the plumbing system.
Step 5.
With an appropriate tool, such as a pipe wrench, remove the outlet
nipple/anode from the water heater. Use caution not to damage the pipe threads.
Step 6.
Visually inspect the outlet nipple/anode. The outlet nipple/anode should
show signs of depletion, which is normal. If depletion is one-half the original anode
diameter (approximately 3/4" diameter), replacement is recommended. If any of the
steel core of the anode is exposed, replacement is recommended.
Step 7.
Upon completion of the inspection or subsequent replacement, reinstall
the outlet nipple/anode into the water
system, resume water supply to the water heater, and refill the water heater.
Step 8.
To resume operation, follow the instructions located on the water heater
lighting instruction label. Or, use the lighting instructions located in the water heater
installation and operating manual.
