I've read various thoughts on the effectiveness of sacrificial zinc anode's, and whether or not they're necessary; thinking of installing one because I figure it couldn't hurt. I've seen the recommendations for the $17 '6 lb Crab/Lobster Pot Zinc Anodes' on Amazon and the numerous posts saying to connect it tot he bonding system and bury it in damp soil, but nothing that shows pictures or really gives any details on exactly how to do that.
Our equipment room has a square cut out of the floor where the PVC lines come in; in there is also where all the grounding wires connect:
Is it really just as simple as burying the anode, connecting it to that ground stake with the rest of the grounding wires, and then keeping the ground damp where it's buried? Or is there something else to it?
What's the best way to attach it? Copper wire either clamped and screwed onto the anode or wrapped around it?
