Sink stain emanating from overflow hole
This isn't a problem I need to fix, just a curiosity I wonder about.
We have a sink that is used lightly. It never has the stopper in, it is never filled, there is never a reason for it to have water enter the overflow. The overflow hole is on the near side, the faucets on the far side. And yet, it has developed a tan stain obviously starting at the overflow and extending down towards the drain. I don't see any sign water has ever come out of the overflow, nor do I see why that would happen, but there has to be some reason for this. |

Put some water down it and flush it out and it may help. |

You wash down all sort of caustic and organic materials and they sit in the trap where that overflow connects. Some washes back in the bottom of it. sits and oxidizes. Then it gives off gasses that rise and coat things. |

But doesnt move out the overflow down to the drain. The stain is exactly where liquids would flow and shaped like they would be.. But it's hard to see a backup happening out the overflow that didn't also show at the drain. I thought of fumes, but they would have to be heavier than air. I scrubbed it off this morning, too late for a photo. If it recurs I'll do that. This is the sink I use to brush my teeth, I don't think wife or daughters ever use it, certainly not on a regular basis. So it gets about one drinking glass of water per day, but that's every day. On the other hand. About ten years ago I replaced the faucets in that sink.. I don't remember why but I wouldn't have done that job without a darned good reason. I do remember the old ones didn't want to come out, I think I beat on them with a rubber hammer for a long time before they moved. I had to pull the sink from the vanity into the backyard to get it apart. So it's not impossible I screwed something up when I replaced it. But it hasn't backed up or dripped underneath, so I can't have done too badly. |

But doesnt move out the overflow down to the drain. The stain is exactly where liquids would flow and shaped like they would be. Thats the crucial detail that needs to be explained. But it's hard to see a backup happening out the overflow that didn't also show at the drain. That might well be due to how the overflow comes into the drain before where the plug goes in the drain hole. I thought of fumes, but they would have to be heavier than air. And wouldnt produce a stain that looks like liquid running down. The stain would be much wider and less defined even if the fumes were heavier than air. I scrubbed it off this morning, too late for a photo. If it recurs I'll do that. This is the sink I use to brush my teeth, I don't think wife or daughters ever use it, certainly not on a regular basis. So it gets about one drinking glass of water per day, but that's every day. Since you never put the plug in and never fill it, I'd block the overflow with something and see the stain never show up again and then block it permanently but so that the block can be removed if you sell the place or start using it as a filled sink again later etc. On the other hand. About ten years ago I replaced the faucets in that sink. I don't remember why but I wouldn't have done that job without a darned good reason. The usual reason is because you cant stop it dripping and cant work out how to replace the washer seat etc. I do remember the old ones didn't want to come out, I think I beat on them with a rubber hammer for a long time before they moved. Yeah, they can seize quite easily with some poor designs with no way to get enough leverage. I had to pull the sink from the vanity into the backyard to get it apart. So it's not impossible I screwed something up when I replaced it. Yeah, maybe so a backup ends up with enough backing up the overflow to be enough to stain the sink with that dirty backup. But it hasn't backed up or dripped underneath, so I can't have done too badly. But might have ended up with some sealant etc that you used to stop it dripping redirecting a backup up the overflow accidentally. |

If you have the bowl filled with water and suddenly open the drain, the pressure of the water at the drain will surge water into the overflow drain tube, perhaps enough to splash some out through the drain hole or above it where it can then run down and out. |

I now have new information.
I did not know my daughter hand washes some types of clothing in a big tub and dumps it into that sink. I'm guessing that may be the source. |
