CHAPTER 10 – MAINTENANCE
10.3.2 Buffer Tank Anode Rods
The buffer tank anode, located as shown in Figure 10-14, should be checked every six months,
and replaced once a year.
Figure 10-14: Buffer Tank Anode Location and Diameter Inspection
At the 6 month inspection, unscrew the anode from its port and check the reduction in anode
diameter. Original anode rod diameter is 3/4” (0.75”), and anode should be replaced if diameter
is reduced by 20% to 3/5” (0.60”) diameter or less. Figure 10-14 shows a comparison of an old
anode needing replacement, and a new anode.
Contact AERCO Technical Support for replacement anodes.
