[A/S] Black Stuff in "City" Water

[<hhamp5246@xxxxxxx>]

Hi Gang,

I'm now at the Escapee Park just north of Knoxville. I hooked up to water and
walked the dogs. Got to cleaning my bathroom inc. my toilet.  When I flushed
the toilet little black specks of something came running down the walls with
the clean water. It looked like little black rocks.

Then a little while later I turned on the kitchen faucet and just a little
trickled into the sink...very little.

I went out to be sure the water was on and it was.  I checked my water 
filter,
works fine. The bathroom sink worked fine too.

I unscrewed the kitchen faucet and the little screen was chock full of the
black speck stuff..... 

When I hooked up I ran water completely through the hose before attaching it 
to
the trailer inlet.

What's the black stuff?  Where did it come from?  Has this happened to anyone
else? It's not from a charcoal filter, the only filter I have is under the 
sink with its own tap.
