I was asked to look at a re-model today where, the water heater anode is corroding. The water service is copper and bonded correctly at the service with a #4 solid CU to the main panel. There is a ground rod at the main also bonded correctly, then the electrician went a step further and ran a bond wire from the main panel to the water heaters and jumped the Hot, Cold, and Gas pipes. All the neutrals and grounds are correct and only bonded at the main panel. So all the plumbing and electrical look good, and are installed correctly. There are two 50 gallon water heaters side by side, and the entire water system is copper. The anodes in both water heaters are degrading so fast(less then 3 months) that when the home owner fills the bath tub there is a residue in the tub after draining. These are new heaters and have magnesium anodes not the normal aluminum ones. When they are removed from the tank they look like they are 20 years old.
Has any one else run into this problem, and what did you find ?
P.S. the water quality in the area is good and no water softeners needed.
