Magnesium Anode Rod
Magnesium rods are excellent sacrificial rods, used to protect the inside metal surface of your water heater tank. The magnesium corrodes instead of your tank. Magnesium anode rods tend to be consumed quicker than Aluminum or Aluminum/Zinc/Tin anode rods due to the higher voltage they create during the sacrificial process.

Aluminum/Zinc/Tin Anode Rod
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.

Aluminum Anode Rod
Aluminum anode rods are the least expensive and create the lowest voltage during the sacrificial process. This means they will usually corrode at a slower rate than the other anode rods we offer. Actual water conditions will vary and have a direct effect on how quickly an anode rod corrodes and dissolves.

Flexible Aluminum Anode Rod
Flexible aluminum anode rods are designed for those limited spaces where a straight anode rod will be unable to be inserted into the water heater due to limited access directly above, such as low ceilings, closets, attics, under stairwells or in basements.
