Lochinvar water heater shows signs of rust around the anode rod port or hot outlet connection.

Safety: Turn off power or gas and allow the tank to cool. Relieve pressure by opening a hot water tap before removing the anode.

Steps:

• 1. Inspect anode rod: Remove the anode rod from the top of the tank. If it is less than 1/4 inch thick or heavily pitted, replace it.
• 2. Clean threads and port: Remove rust from the anode port threads and apply pipe sealant to the new anode rod threads.
• 3. Install new anode: Install a Lochinvar-compatible anode rod (magnesium or aluminum/zinc depending on water quality).
• 4. Schedule maintenance: Plan to inspect the anode every 2–3 years to prevent future corrosion.
