Overview

The Lrichy 4.5-inch magnesium anode rod is a practical replacement designed for Atwood and Dometic RV water heaters. This 2-pack helps protect the tank and maintain efficient heating during your travels, offering a straightforward upgrade for ongoing maintenance.

Materials and Benefits

Crafted from AZ31B magnesium alloy (95.5% Mg) with a chrome-plated head, the rod delivers strong corrosion resistance and durable performance. Magnesium ions help soften hard scale, supporting easier flushing and keeping the heating element cleaner over time.

Durability and Design

Built for reliable resistance to breakage within the tank, this anode rod can extend service life and reduce the frequency of replacements in demanding RV environments.

Easy Installation

  • Includes a quick-release socket wrench for fast, tool-friendly installation
  • Teflon waterproof tape helps seal the connection and prevent leaks
  • DIY-friendly replacement that can be completed in minutes

Safety and Care

  1. Always turn off power and water, completely drain the tank, and relieve internal pressure before installing
  2. Review installation guidance and videos to understand important precautions

Maintenance and Support

Note that water quality affects corrosion rate. Regular inspections (quarterly is recommended) help maintain protection. The purchase includes a 2-year warranty and a straightforward return/refund option for a hassle-free after-sales experience.
