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?
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.
When cleaning anything including baby diapers, it is better to sweep off or scrape off as much solid and semisolid material as you can first. (1) Less cleaning fluid or detergent needs to be used, (2) Less of a mushy mess which in turn means that bleaches or disinfectants will be more effective.
