On Board water runs black?!
We have just commissioned Mad Hatter for the new season and I have an interesting issue with the water system.
The water flows intermittently clear and clean and then goes black for 30 seconds or so, then runs clear and clean again, then back to black. And so on.
Any ideas what this 'black' colouration might be? It seems to be from both hot and cold water supplies, whether dock supplied or water tank supplied. It runs the same to sinks and heads.
I have water treatment sitting in the tank now. Any ideas are appreciated!
