I went to fill a water bottle from the kitchen tap and was amazed at what came out. The bottle was loaded with black flakes and the water seemed discolored. I touched some of the flakes and they just smeared and appeared to be a bit greasy. I ran the water a bit more and it got better a short time later. The water in the bathroms and the laundry room sink are all fine, as is the water from the hose hook-ups outside. Does anybody know what this was or where it came from? The laundry room sink is closest to the water heater and is ok so I don't think the heater would be it.
We had a new faucet installed about 10 months ago.
Any help/suggestions appreciated.
Walt.
