For some time I have noticed an increasing amount of black flakes exiting with the hot water in my bathroom sink. The flakes swim on the water surface. They are very thin and tend to disintegrate when I touch them. When I try to wipe them from the surface of the sink, they become e 'smear' which takes a household cleaner to remove. After some running the tap water gets clean and stays that way for a day or two. The problem occurs only in the two sinks of one bathroom, not the other bathrooms nor in the jacuzzi of the same bathroom. Any idea what those black flakes might be and how to get rid of the problem would be much appreciated.
