Suburban Water Heater Magnesium Anode Rod 233514

The Suburban 233514 Magnesium Anode Rod is the OEM replacement anode used in Suburban tank-style RV water heaters. It helps protect the steel water heater tank from internal corrosion by sacrificing itself before the tank begins to deteriorate.

The anode rod also serves as the water heater drain plug, making it a key maintenance item for Suburban SW Series water heaters. Regular inspection and replacement can help extend the life of the water heater tank and prevent costly tank failure.
