I just installed a new Kohler cast iron/porcelain kitchen sink and have discovered a hairline crack in the porcelain about 2 inches long running out from under the drain collar. How bad is this? To be specific, is it so bad that I should replace it, as this would entail pulling and then reinstalling all the plumbing as well at the countertop? (It's an undermount sink, of course). The Kohler warranty would only cover the sink itself and none of the labor, so swapping it out would cost me a bunch. And I need to decide soon, since putting up the backsplash is the next project, and that will further complicate the process by making it harder to pull out the countertop.
Right now, the crack isn't getting worse, and it isn't that unsightly. I can live with it, but if it's going to get worse, or if it's going to cause the sink to rust out in the next, say, 10-15 years, I'd probably want to replace it. Also, is there some compromise solution--some way to seal the crack so that it won't seep and cause damage to the cast iron below?
