The bronze seacocks on our CD28 develop a green crystalline residue on them, especially the head intake cock. I'm assuming the crystals are salt and the green is the result of some sort of reaction with the bronze. There is no evidence of leakage or weeping around the seacock. Should I be concerned about this? Is it indicative of a problem. What can I do to prevent it?
