The Suburban Aluminum Anode Rod is a replacement anode rod for Suburban RV Water Heaters that will preserve the life of the water heater by corroding themselves, so the water heater doesn't get corroded.

The RV water heater anode equalizes aggressive water action. All Suburban water heaters are protected by a magnesium or aluminum anodes to prolong the life of the tank. Under normal use, the anode rod will deteriorate. Because of this, we recommend it be replaced annually or when consumption or weight loss of the rod is greater than 75%.
