O.K. guys and gals, here, I believe, is a new one...

I've never seen this problem posted before so...here goes: When the coach has sat unused for a few days and I then turn on a water faucet - kitchen or bath, it runs pure black water for a couple seconds then clears up. It seems that when water sits in the piping, it becomes black. As soon as the water that was sitting in the piping runs out and water begins coming from the holding tank, it clears up. Is there black piping that might be deteriorating causing the black water? Will appreciate any thoughts about this...whatever it is! / Larry

Its the guts to your charcoal water filter dieing. Flush everything and install a new filter and reprogram it.

That, or if you have a filter on the fresh water tank water system, that has a charcoal filter that is dissolving.
