I have had the Indigo heat exchanger for a few years, and realized I need to change the anode!
When I took off the brass cap all that was there was a small wire (like a brad) and some zincy goo. Access is poor, so I could not see well what was holding the "brad" in place. I tried to unscrew what was there gripping the wire with pliers, but instead, the wire pulled straight out clean...with a fair amount of resistance.
I am concerned that the remaining anode (if any) will fall into the exchanger now that it is unsupported by the wire. Am I over worrying? I would figure that the anode was simply eroded away, but what was holding the wire in place? Seems like three paths to pursue:
1. clean out the old anode residue as well as possible in place and install a new anode.
or
2. remove the heat exchanger completely, give it a good flush and clean.
or
3. re-install the wire so it supports the remaining zinc.
Time is short before we have to be out of our dock spot!
Pencil anodes are new to me, so any advice appreciated.
