I replaced the anode rod in my electric hot water heater because of the smell. the smell went away after about 3 weeks. two months later, the smell is back and seems to be worse. any suggestions?
Aluminum/Zinc/Tin Anode Rods
This particular combination of metal in anode rods is often used when foul odor in water is present. Zinc is a natural anti-fungal element and can help control (not completely eliminate), the growth of iron bacteria which can cause that rotten egg smell. Zinc oxide and zinc compounds are indigestible to micro-organisms such as bacteria. This combo rod is designed to fight some foul water odors that can occur in water heater systems that use aluminum or magnesium anode rods. Please read our FAQ for more information regarding water odor.
