Camco 11533 Magnesium Anode Rod 4-1/2" x 1/2"-14 NPT for Atwood Water Heaters

The Camco 11533 magnesium anode rod is specifically designed for aluminum water heaters with Atwood-style drain configurations. This essential component extends the life of your RV water heater by attracting corrosive elements in the water, sacrificing itself through electrolysis so your water heater tank doesn't corrode.

Key Features:

• Magnesium construction provides superior corrosion protection for aluminum tanks
• 4-1/2 inch length with 1/2"-14 NPT thread size
• Replaces standard drain plug while adding protection
• Functions as both drain valve and sacrificial anode
• Compatible with Atwood-style RV water heaters
• Easy installation - simply replaces existing drain plug

Regular replacement of your anode rod is critical preventive maintenance that can add years to your water heater's lifespan. Inspect the rod annually and replace when more than 75% of the core wire is exposed or the rod is severely corroded. This simple maintenance step protects your investment and ensures reliable hot water in your RV.
