Anode Rod

I am getting ready to replace abaout 3 anode rods in water heaters for rental units.
Because of clearance issues, I will need to get flexible ones. Since I will be ordering several I need to get this right.

There seem to be several material choices with some big price differences.
Which metal is best? Which is best value? I live in an area with very hard water: Does that make a difference?

Check with the manufacture of the water heater. Some are different materials

Magnesium protects the tank better than aluminum although sometimes magnesium results in bad odors to some kinds of hard water. Aluminum is better than zinc.

Choose the best anode material for the water and situation even if it costs more.
The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.
