Camco 11553 Magnesium RV Water Heater Anode Rod, 1/2-Inch NPT for Atwood-Style Drains
A magnesium sacrificial anode sized for the 1/2-inch NPT drain opening used on Atwood-style RV water heaters: 4.5 inches long, 0.5-inch diameter. Camco lists it as Atwood-compatible. Atwood's own manual specifies only a nylon drain plug for its aluminum tanks, so treat this as the optional upgrade for that port and the direct replacement for a rod that is already in place. Suburban tanks use a 3/4-inch port and a 42-inch rod instead.

Outdoor adventures come with unique gear challenges — space, weight, durability, and weather resistance all matter.

🏆 How It Compares
Compared to alternatives in the rv accessories category, the Camco 11553 Magnesium RV Water Heater Anode Rod, 1/2-Inch NPT for Atwood-Style Drains excels with fits the 1/2-inch npt drain opening on atwood-style heaters: 4.5 inches long, 0.5-inch diameter and magnesium is the faster-sacrificing alloy, which is what you want as a direct swap for a rod already corroded to its steel core. However, keep in mind atwood's manual calls for a nylon drain plug only, so on an untouched atwood tank this is optional maintenance rather than a required replacement and will not fit suburban heaters (3/4-inch port, 42-inch rod), and magnesium is consumed faster than aluminum in hard water — consider whether these factors align with your specific needs before purchasing.
