Rheem SP11309C R Tech Magnesium Anode Rod – 44in x .700in

Overview

Rheem SP11309C R Tech magnesium anode rod is a purpose-built sacrificial component designed to shield your water heater tank from internal corrosion. Produced by Rheem, a trusted name in home heating and water heating, this rod is sized to fit compatible Rheem systems and repair kits, helping you maintain steady hot water delivery and system reliability over time.

Choosing the right anode rod matters. Magnesium is known for its strong sacrificial action, reacting preferentially to corrosive elements inside the tank.
