Black/Gray Water
Author: co2mc (MN) Hi I'm in a rental and some work was done to the bathroom sink. It looks like the j-trap was replaced. When we first turned the sink back on the water ran black/purple and then finally clear. Now it is pretty much clear but sometimes black/gray... especially if we turn the shut off valve. Why is this? Is it safe to drink? Our landlord is no help. Thanks

Author: steve (CA) That's a common occurrence when an older angle stop is closed and opened. It's from the rubber seals that are deteriorating. I would just allow the water to run until clear.
