Built with an aluminum body and a commercial-grade stainless steel core, it preferentially corrodes so the tank walls remain protected. Installing a fresh anode rod is one of the easiest ways to reduce tank deterioration, avoid premature leaks and delay costly water heater replacements.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the anode rod protect my RV water heater?\u003c\/h3\u003e\n\u003cp\u003eThe anode rod works by corroding before the steel tank does, a process called sacrificial protection. The aluminum alloy attracts corrosive elements in hot water, so the metal of the rod is consumed instead of the tank lining. Using the right anode for your tank chemistry helps keep the porcelain-lined surface intact longer.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum outer body with stainless steel core for reliable sacrificial action\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for Suburban porcelain-lined tanks\u003c\/li\u003e\n  \u003cli\u003eReduces rust formation and delays tank perforation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIs this anode rod easy to install in an RV?\u003c\/h3\u003e\n\u003cp\u003eYes — the 233516 is sized for straightforward replacement and fits common Suburban water heater fittings. With a 3\/4\" threaded connection and a 9\" length, it can be swapped with basic tools in most installations.
