Suburban Mfg 233516 Aluminum Anode Rod 9 Inch 3/4 NPT

The Suburban Mfg 233516 Aluminum Anode Rod is a critical replacement component designed to protect RV water heaters from corrosion and significantly extend tank life. This sacrificial anode rod corrodes in place of your water heater tank, absorbing the electrolytic action caused by heating water and preventing damage to the tank itself.

Key Features:

• 9-inch length with 3/4-inch NPT (National Pipe Thread) for easy installation
• Aluminum construction specifically formulated for hard water conditions
• Replaces the standard drain plug to provide continuous tank protection
• Compatible with Suburban aluminum tank water heaters
• Also functions as the tank drain when removed

Maintenance Benefits:

• Absorbs corrosive action before it damages your water heater tank
• Regular inspection and annual replacement maximizes water heater lifespan
• Best suited for high pH and hard water environments
• Simple screw-in installation requires no special tools

Check your anode rod condition every time you drain your water heater. If the rod is significantly corroded or eaten away, replace it immediately to maintain optimal tank protection. Keeping a spare anode rod on hand ensures uninterrupted protection for your RV water heating system.
