I have a heat exchanger custom made by Sendure. When it was being
designed I was asked if I wanted a fitting for a zinc. My old heat exchanger
had one so I had them put one in.
Now I'm wondering just how important that zinc is. It's in the salt water
flow and gets eroded somewhat quickly. The heat exchanger is
mounted on a bulkhead, so the only "electrical" connections to anything
are the fresh and salt water lines.
Should I keep replacing this pencil zinc or not worry about it?
