At 42 inches in length with a 3\/4-inch hex connection, this rod threads directly into the water heater tank and undergoes controlled electrochemical oxidation in place of the tank wall. It is also formulated to reduce hydrogen sulfide odor, commonly experienced as a rotten egg smell, that can develop in water heater tanks with certain water chemistries. Licensed plumbers and water heater service technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis anode rod is used in residential water heater applications where the existing magnesium anode has depleted or where sulfur odor problems require a switch to an aluminum\/zinc alloy formulation. The 42-inch length suits standard tall tank configurations. The 3\/4-inch hex end allows installation using a standard socket wrench. It is sold as a direct replacement part for water heaters originally equipped with a comparable anode rod of the same connection size and length.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum\/zinc alloy construction provides sacrificial corrosion protection for tank interior\u003c\/li\u003e\n  \u003cli\u003eFormulated to reduce sulfide-related odor in water heater tanks\u003c\/li\u003e\n  \u003cli\u003e42-inch length suits tall residential storage water heater tanks\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch hex connection for standard socket wrench installation\u003c\/li\u003e\n  \u003cli\u003eReplacement part application — direct drop-in service for depleted or failed anode rods\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement anode rod for residential storage water heaters equipped with a 3\/4-inch hex anode port accepting a 42-inch rod.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber. Before servicing, shut off the cold water supply and power or gas to the water heater, and relieve tank pressure at the temperature-pressure relief valve. A 1-1\/16-inch or 1-1\/8-inch socket with a breaker bar is commonly required to break loose the existing anode rod. Apply thread sealant tape to the hex fitting threads before installing the replacement rod and tighten to snug — do not overtighten, as tank threads can be damaged.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum\/Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 42 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Replacement Part\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: AO SMITH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 100108571\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TAILWIND","offers":[{"title":"Default Title","offer_id":51149916078386,"sku":"100108571","price":94.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305987628.jpg?v=1778602445","url":"https:\/\/voomisupply.com\/products\/ao-smith-100108571-anode-rod-42-in-aluminum-zinc-3-4-hex","provider":"Voomi Supply","version":"1.0","type":"link"}
