Corroded Boiler part?

lowwater Member Posts: 41
I have a Weil-McClain cg-25-spdn boiler which works fine. Upon annual

cleanup (which I always do) I noticed this part corroded which I believe is the automatic vent. Is it normal and I should have this replaced? What are your thoughts? Much appreciated!

    Most definitely

    have that vent replaced. I think that's a Maid-o-Mist- there are better ones out there.
