My husband re-did the plumbing to our clawfoot tub 8 years ago. He put in chrome supply lines that come up from the floor. I noticed what looked like a line of corrosion going down the hot water line today. Turns out it wasn’t corroded but I think it would have eventually. It was white water stain that was a little difficult to get off. Once it was cleaned I noticed 3 tiny black marks I couldn’t get off. Then I noticed a bead of water forming on each of them. They just sit there for a long time without dripping, but no doubt that is what had been happening. As soon as I wipe the bead off another one appears. I have a couple of questions.

If I ignore it for awhile and just keep wiping them off, will it be a long, long time before it’s a serious problem and will I be able to tell it’s time to get it fixed or else it’s going to gush out?

I looked up the prices for supply lines and WOW! I don’t remember spending that much when we did it. The cold water one is fine. I don’t remember where we got them, but I know it wasn’t a Home Depot type place. We had to research hard to find the best we could from specialty plumbing places without spending a fortune. Is there anyway those holes can be patched without it looking terrible? The dots are already black and very tiny. Can I get some kind of stuff even if it’s black to put a dot over them? Would that work?

Thank you very much. Dale
