A galvanic anode is the main component of a galvanic
cathodic protection (CP) system used to protect buried or sub-
merged metal structures from corrosion.
Anodes are made from a metal alloy with a more "active" volt-
age (more negative electrochemical potential) than the metal
of the structure. The difference in potential between the two
metals means that the galvanic anode corrodes, so that the
anode material is consumed in preference to the structure.
Anode
The loss (or sacrifice) of the anode material gives rise to the
alternative name of sacrificial anode.
As this device is made to deteriorate, it begins to "die" the
minute it is placed in the water. To be effective, it must have
good contact with the material you are protecting, and have
good exposure to the water. With this in mind, remove and
clean the contact surfaces. A wire brush works well for this.
If the anode looks like swiss cheese, it has lived its useful life
and needs to be replaced.
Replacement anodes available at j&j. # 37398101
To remove, clean, or replace the anode, remove the bolts
Apply silicone to the bolt threads before installing anode.
