Flexible Combo Aluminum/Zinc Anode Rod, SKU14
This is a flexible combo aluminum/zinc anode with a 4-inch PEX-lined pipe nipple that requires about 14 inches of clearance. It’s .75-inch diameter and 48 inches long. Includes pipe-thread seal tape, service sticker and instructions.
Most Bradford White and some State, A.O. Smith and Reliance heaters use this type of anode.
It will keep your water heater from rusting while reducing or eliminating odor problems because of anaerobic bacteria found in some water that react with regular magnesium or aluminum anodes to produce hydrogen sulfide gas and a rotten-egg odor. It’s most likely to solve this problem if a water softener is NOT being used.
