Product Details
✓🏆【Extend Service Life and Soften Hard Scale】This Lrichy 1/2" x 4.5" magnesium anode rod is suitable for Atwood/Dometic RV water heaters and is the perfect replacement for the original drain plug. Magnesium ions soften hard scale for easy flushing, keeping the heating element clean and efficient while sacrificially protecting the tank liner from rust, avoiding costly repairs
✓🏆【Durable and Reliable】Crafted from premium AZ31B magnesium alloy (95.5% Mg)and chrome-plated at the head, it offers exceptional strength and corrosion resistance compared to standard rods. Enjoy a longer service life, reliable resistance to breakage within the tank, and fewer replacements. (Note: Water quality affects the rate of corrosion. We recommend quarterly inspections and replacements for optimal protection
✓🏆【Quick Installation】Equipped with a quick-release socket wrench and Teflon waterproof tape, installation is simple and fast, and can be completed in minutes even when installing it yourself
✓🏆【Critical Safety Precautions】Before starting installation, ALWAYS turn off the power and water supply, completely drain the hot water tank or wait for the water to cool (to prevent burns!) and release all internal pressure via the pressure relief valve. It is recommended to watch some videos and review materials to understand important precautions
