Eliminates smelly water issues caused by sacrificial magnesium anodes.
Protects for years; no maintenance required.
Great for softened water applications.
*Protection is maintained as long as the control module remains connected to a power source.
Smelly water conditions typically occur in private wells located within the high water hardness areas shown above.
In areas with sulfides in the water, there is a reaction with magnesium anodes which creates hydrogen sulfide gas that produces a rotten egg smell in the water. Smelly water conditions typically occur in private wells located within the high hardness areas shown in the water map below. In other areas with high conductivity water, aluminum anodes create an aluminum hydroxide gel that decreases the efficiency of the heater and quickly depletes the anode leaving the tank unprotected. This next generation of anode provides consistent protection that extends the life of your water heater tank. Since no chemicals are added to the water as with sacrificial anodes, the Powered Anode System will not create smelly water or aluminum hydroxide.
